I have an HP Pavilion dv7-1245dx that I recently installed a new battery for. I booted up the laptop and it (I think?) failed POST. The Caps Lock and Num Lock keys flash four times and after a while it powers off. No display, not even when hooking it up to an external monitor. I looked through the guts of it and made sure everything was hooked up and connected properly. Nothing seemed wrong, but I did find a missing HDD. The Pavilion comes with two, and after looking through the other one, I can confirm that the hard drive I still have is the boot drive. Is there something I'm missing?

Hey, Ive recently created a post about a booting problem: In a nutshell, i forced the PC to turn off during boot cycle. Afterwards I kept stuck booting with no post (r5 7600, 32gb Flare X5 6000Mhz ram, B650i Lightning). On this mainboard, the Power LED kept blinking at a frequency of ~ 2Hz. Going into manuals, this led me to a failure in Ram OC. Since no one was able to help, I ordered a Mainboard (MSI B650i edge wifi) and a spare pair of RAM to troubleshoot. Now, as stated. DRAM and CPU debug LEDs are led. I used the new RAM and Mainboard. Only the CPU (and my SF750) is from my build. Since the problem seems to consist, is my CPU dead? And if so, how in the world did that happen? To rule things out, i let the test system do its things, as I know DDR5 can take some time upon first boot, but after 30mins no change in sight. I have tried the old RAM on the new Board and the new RAM on the old Board. Just to be clear, as some of you may not want to read my old article, the problem ist definitely not solved by clearing the CMOS. I ruled that out. One last step I could try is to use the Bios Flashback on the new Board to load the newest BIOS. But the button does not trigger the flashback process, though the name of the file, the slot and the stick was formatted correctly. Furthermore, I doubt it will help since useing BIOS Flashback didnt help on the old board neither. By old I mean a four months old system consisting out of only new parts. As I did all testing without a GPU. So a GPU problem can be ruled out (same for my ssd). I hope someone has a tip. I was hoping the Debug LEDs could help me figure out the problem, but I find it hard to believe the CPU just died. Cheers

Hey, Ive built a PC approximatly four months ago. But today I ran into a problem which I could not resolve by my own. I have noticed on this AM5 system that every 2-3 weeks, the boot cycle takes 5 minutes. I always thought thats because of the new platform. Usually I wait this time or it also worked to press the power LED one time more, then the system would power down and I can start again with a normal boot cycle that time. Same happend today. I turned it off and started again. But now the power led of the mainboard (Asrock b650i lightning wifi) keeps blinking at around 2Hz. Goining after the manual, that means "blinking till BFD" with the discription "DRAM overclocking failed" (page 40 of the manual). First of all, what is BFD? Secondly, I waited ~30 minutes without anything happening. I started my usual troubleshooting steps (which is extremly painful in my SFF build by the way). This consisted of trying out single ram (32GB Gskill Flare 6000Mhz, EXPO ready), resetting BIOS ~5 times via jumper and battery and running of onboard graphics (r5 7600) without a GPU in the Pcie slot. I dont think its a problem with my power supply, because its a fresh SF750, which is a good psu in general. I honestly dont know what to do next. My only idea is to just let the system do whatever it is doing for a long time and hope its gonna fix itself. Ive heard that in rare cases DDR5 takes longer than half an hour to boot after a BIOS reset. On first boot four months ago I think it took about 15min in my system I would be grateful for any help you can provide. Cheers

Just finished my new build and it won't post. No signs of life after i try to turn it on; no mobo LEDs ever come on, no fans spinning, no other RGB come on like from the ram, except the Mobo RGB that's near the back IO does come on when the PSU is switched on, not when turning on PC. Seems like this this RGB is always on even if the computer is off. I've tried updating bios using my 32GB USB and following ASUS' guide and two PC YouTubers very cautiously. But, the green light in the bios USB header never stops shining (no flashes, just a constant, solid green light) I do have to admit that my case, p400a, front panel IO cables felt a bit weird and that im not 100% sure the way I connected it is right, even after staring at the mobo manual for an hour, if that's the case that might explain why I'm not getting any LEDs when attempting to turn on computer because the power switch is connected in a wrong way. I've read many others recently have had the same problem as me with the same motherboard, not sure if it could be incompatibility with two parts, like maybe the new corsair RAM and the mobo?

I'm currently working on an older build for a friend which I've completed and tested for several hours last week with these specs. i7 7700 H110M 8GB DDR4 2666Mhz GT 610 (As a test GPU) Today, I tried to turn in back on to check if everything is ok before he picks it up, and to my surprise it doesn't post and for some reason started boot looping indefinitely when I tried to restart it by unplugging the power. I removed the graphics card and for some reason the PC boots up as normal, loads into windows and works perfectly fine. I then reinstalled the graphics card to see if it was dead and for some unknown reasons, it still turns on and works as normal. Is this quite normal or is there something that I should be aware of? Any help would be appreciated.

Hello everyone. My system with specs listed below has been running into error code 0d with no post. The system has been offline for 8 days as I have been out of town. Before I left, I shut the system down and shut down the UPS the system was connected to. Prior to leaving, the system did not experience any issues and was fully functional. All the fans run continuously and RGB lights do power on including the keyboard. But the lights for caps lock and number lock do not illuminate. In addition to the error code 0d, the post code does occasionally cycle through codes as shown in the video below.

I have a old Asus X99-Pro board that has worked great for years. On the morning of Jun 23rd I discovered the machine restarted overnight and was stuck with post code 00. I tried restarting the machine multiple times and still had post code 00. None of the fans were spinning. I had a i7-5820K installed in the board when this happened. I updated my BIOS from 0401 to 3801 on June 16th to do a RAM upgrade. The machine had no issues after the update until Jun 23rd when this incident happened. Asus support said I had a dead CPU but I am not very confident in ASUS support due to my experience with a issue with a different board on my newer machine. I just installed a used Xeon E5-2683 v4 into the board that I got from a surplus seller on eBay. The new CPU is on the QVL list for my board. My board still has post code 00. I have tested this board with nothing installed in it and got post code 00. I also tried with only each CPU installed and still got post code 00. I also tried with a CPU and a single stick of RAM and still post code 00. In all of my testing I was not able to get the fans to spin. I do have the power and reset LEDs on my motherboard when my PSU is on. I have tried using USB Bios Flashback to install BIOS 0401 and 3801 on my board with no improvement. The bios flashback function appears to work but I still get post code 00. I am wondering if there are any other tests I can try? I do not want to spend $200 on a new X99 board but I am willing to spend money on tools (Like a PSU tester). My PSU is a Corsair RM750 so the PSU fans do not spin when I use a jumper on the PSU. I was able to power a CD drive with my jumped PSU. Any advise is appreciated.

I recently build a new pc and i put it all together and it didnt boot I realized that i messed up when i put the cpu in and took it out and had 9 bent pins i fixed the pins and put it back in and it booted but not fully but had a yellow ram light flashing but no post or display so i tried reseating the ram stick and just using one and nothing so i wrnt and bought a new cpu thinking the old one was dead and it still didnt do anything so i tried a ram stick that i knew worked and it booted fully everything was on but it didnt post or have a display and the yellow light was solid now and it had a red cpu light flashing every 3 seconds my last option it to get a new motherboard but if anyone had any suggestions please let me know the specs of the build are a ryzen 7 5800x and a nvidia geforce rtx 4060 with 2x16 3200 ram and 2tb 3600mb/s crucial nvme

Hey guys, recently ive upgraded my cpu to a ryzen 7 7800x3d. Naturally i bought new ram (corsair vengeance ddr5 2x16) and motherboard (ASRock A620M Pro RS) as i was upgrading from an i7 with ddr3 memory. When I put everything together i get no post whatsoever. The only thing that happens is rgb on the back of the motherboard turns on (it stays on constantly as long as the 24 pin is connected). Anything else such as fans, cpu cooler, power supply, gpu fans stays off. There are also no sounds or error leds turning on, as this motherboard has a couple leds. Things I've tried so far: -Graphics card (4060ti 16gb) and power supply (corsair cx750) work fine when plugged into the old parts) -Re seated cpu -Tried powering it without the graphics card plugged in -Returned and ordered brand new ram sticks, plugged one stick at a time, checked the manual for the right sockets -Tried shorting the power pins for the front pannel, the power button works fine on the old mb -Tried plugging the cpu cooler in the other cpu cooler socket, cooler works fine on the old mb Does this sound like a dead cpu or dead motherboard to you? Personally im down to these last 2 options but im open to other suggestions. I dont have any other am5 socket cpu or motherboard to test either of them so id rather get another opinion before returning one or the other. Thanks in advance Detailed parts list: -MB: ASRock A620M Pro RS - 90-MXBLN0-A0UAYZ -CPU: AMD Ryzen 7 7800X3D 8x 4.20GHz So.AM5 -RAM: CORSAIR Vengeance DDR5 RAM 32GB (2x16GB) 6000MHz CL36 AMD -PSU: 750 Watt Corsair CX Series CX750 Non-Modular 80+ Bronze -GPU: 16GB MSI GeForce RTX 4060 Ti Ventus 2X Black OC Aktiv PCIe 4.0 x16 (x8) -Cooler: be quiet!

Hello LTT community, I'm reaching out for help regarding an Intermittent issue I've been experiencing with my PC. Here are the details of my system: PC Specs: Phanteks Evolv Shift Air CASE Ryzen 1800x CPU AMD 6750xt GPU (with Phantkes riser cable) Deepcool 850 ATX PSU Aorus B450i Mini ITX MOTHERBOARD 8x2 (16GB) DDR4 Corsair Vengeance RAM 2133 500GB NVMe DRIVE Noctua NH-L9i CPU Cooler No keyboard or mouse Software Information: Windows version: [Latest] GPU Drivers: [Latest] BIOS F61 (2021) The Issue: Sometimes my computer fails to POST. When this occurs, the fans and lights turn on, but there's no display on the screen. However, there are instances when the PC boots and functions normally. Troubleshooting Steps Taken: I've already tried the following solutions without a consistent fix: Replaced PSU (Seasonic 650w previously) Replaced RAM (TeamGroup previously) Replaced GPU (GTX970 previously) Cleared the CMOS BIOS defaults Tried HDMI and DP outputs on GPU (Various cables) Tried running with one stick of RAM Added a "motherboard speaker" (error beeps: LONG SHORT SHORT SHORT, indicating a problem related to the video card - AGP error) Various actions like powering off the PSU, turning the PC on and off, waiting, clearing CMOS, reseating RAM/GPU, and unplugging/plugging DP or HDMI cables. Checked that all PSU cables were properly connected. Ensured GPU and RAM were fully seated. Noctua NH-L9i CPU Cooler is installed properly. (Temperatures are normal when PC boots) Different wall outlet Fresh Windows install Additional Notes: The motherboard speaker beeps indicate a video card problem, but the issue is intermittent and challenging to pinpoint. Occasionally, the PC boots after powering off the PSU, turning it on and off, waiting, clearing CMOS, reseating RAM, and unplugging/plugging the display cable. (one or a combination of these) Notably, the beeping error does not always prevent the PC from booting. Plugging the DP/HDMI cable after the beeps sometimes causes the PC to boot and function normally. Steps Not Yet Tried: Update to the latest BIOS version for the Aorus B450i Mini ITX motherboard. Consider testing with a CPU with onboard graphics (if available) to eliminate potential GPU-related issues. Thank you in advance for your assistance! Best regards,

Hello community, I've upgraded my CPU, RAM, MOBO and CPU Cooler. Therefore, I gave my old gear to my younger sister. Here are the components I gave her: - Intel 8700K (CPU) - G.Skill Trident Z RGB 3000MHZ 8GB x2 (RAM) - MSI z370 Gaming Pro Carbon (MOBO) - Cpoler Matser MasterAIr MA610P (CPU Cooler) Here are the rest of her specs: Previously, as I had upgraded to an RTX3080, I gave her my old GPU: an AMD RX 5700XT. She has an LC6550GP2 550w PSU, a 120gb SSD, a 500gb M.2 nvme SSD that has not been initalized yet, and a 1TB HDD. Windows is currently installed on the 120gb SSD. Here's the issue: No post. It boots, everything lights up (cooler, mobo, gpu, RAM rgb, case fans), all the fans are spinning (except for the GPU fans that has a silence mode built-in). When plugged to the monitor, the light indicator switches from orange to white showing that the monitor detects a connection - then it promptly goes to orange again and the monitor goes back to sleep. The monitor works with my PC. The motherboard signals a red light on the DRAM indicator. Further context and details: - Thermal paste is applied. - The system used to house a 4th gen i5 CPU and a GTX960. The case is pretty small and the new components are a very tight fit. (Picture: GPU removed for more visibility). The motherboard is fixed on the case with stand off hex screws. - The components worked with no issues on my PC. - The RAM sticks seems intact (see pics) and the rgb lights up when booting the system - The PSU has a 550w capacity but comes from a Noname brand and hasn't even got a Bronze certification - Her system worked fine with the Intel 4th gen and the AMD GPU rx5700XT I intend to remove all the components and build a cardboard bench outside the PC case. I would love to hear your thoughts about the possible issues and how to address them. I have my own computer at hand, so I can use my own components to see what is happening. Thanks for the help, cheers!

Hi all, I noticed some artifacting and crashing applications earlier today and decided to take apart and clean most of my PC, figuring it was dust causing connection issues for my components. I put everything back together and am now getting hung up on the CPU debug light and my PC now cannot even boot to BIOS. I have tried: Removing all but 1 stick of ram Clearing CMOS, and subsequently replacing the battery Reseating all components and repasting CPU thermal paste Flashing BIOS via USB drive to both the current version it was on and the most updated version I am about out of ideas and would super appreciate any input! The only thing I can think of at this point would be going to the store and buying another GPU to test if that's the problem. Because of the artifacting, it's seeming to me like that's the most likely culprit. I would warranty the GPU, but because I bought it during the crypto mining peak, it came from China. MSI China won't recognize the warranty because it was used outside of their region and MSI USA won't recognize the warranty because it's "not from their region".

Hey, I am having a really weird problem with my pc which I can not figure out from 3 months now, so I am posting here if someone can help. I have a i79700k processor, I am trying to use it on gigabyte Z390 ud motherboard, the pc doesn't boot/post when I setup my pc and the processor gets really really hot in a couple of seconds. I took the motherboard and the chip to gigabyte server center, they tested the board and it worked with their processor, it posted and I saw the bios myself, they tried with my processor, it didn't work. I sent the processor to Intel, got a call from them that the processor is completely fine, they have tested it on multiple board, with stress testing it for 12 hours. I got my processor back and the motherboard, they still didn't work. Processor still over heats, motherboard lights up, ram lights up. There's little lights in bottom right corner of the motherboard it tells that it has detected ram, cpu, gpu but no boot. Now I wonder if the processor is fine, the motherboard is fine why does it not work. It's supposed to be working fine on this motherboard. Thanks for reading! I hope I can get some help.

Hi, Here is my comp-list: cpu: i5-12600k mobo: Asus Rog strix b660-i gpu: rog strix 2060 S ssd (OS): samsung 980GB 970 m.2 ssd: samsung 870 EVO psu: Cooler master V750 SFX Gold Rev.2 chassi: NR200P cooling: H100 240mm rad with total of 4 120mm fans in chassi. (Cooling is no issue) So here is the issue: I just swaped out my GPU to a Asus Rog Strix RTX 3080 TI and now i run in to all sorts of problem. If i unplug the gpu i can use integrated graphics so the computer works fine. But when i plug in the gpu everything goes to hell. No video, no boot device, video thru cpu but it freezes after 5s of usage. When i use integrated grsphics i can clearly see the gpu, it is detected and no errors. But as soon as i change cable from integrated to the 3080 all cinds of issues appear. So my question is. Is this a bad gpu? Or is my power supply simply to weak? The CPU goes up to 80W during boot. please help.

Folks I goofed up. Was moving my current rig into a new case that would fit the 7900xtx i bought myself for my birthday. Consiquently i upgraded my psu to a Coursair RM1000e fully modular psu. The smart move i did was just move the mobo and gpu to the new case with the new psu, test boot to make sure all was good then install the 7900. long story short no boot on the test boot. No psu fan spin, no debug leds on mobo, no visible smoke or sizzling noise. Decided to swap new psu for old and discovered i put the Cpu 8pin into the (old)Gpu and one of the 6+2 pcie cables to the cpu socket. Pretty sure the old setup is toast. Plan going forward take m.2 from old mobo put in m.2 to usb adapter and check if it is still good. if so build new 5950X system once last of the parts arrive Wednsday. Was not expecting to dip into savings but oh well. Boot in safemode since going from a Asus Tuff Gaming to an MSI mobo. Copy last of the files off that m.2 then burn install media for proxmox and win 10. then use that m.2 as a secondary to the new one incase it decides to crap out. Build new vm's for win 10, Linux, and Android-X86. Given the oopsie i just did and the plan i have does anyone see any holes in that plan?

New PC won’t turn on after RMAing half the parts I first tried to assemble this pc about a month ago now and I haven’t been able to get it to turn on once. I’ve sent it to the local pc repair place twice now and I’ve had the mobo and cpu RMAed from Newegg and back and it still is giving me the same issues. Today was my last attempt at rebuilding it and now the Psu is making a weird wurring sound.

Hey guys, and gurls, so, i am currently building a pc for some home lab experiments. Just starting so looked what i could get my hands on for cheap. Installed all the parts, everything went great. PC posted and i installed Ubuntu on it (i know distro choices are something people can get verry woked up over, but i have a lot of experience with ubuntu, so that is what i felt comfortable with for the start). After about two weeks of installing programms, restarting the pc on ocassions and everithing going i restarted the pc once again, but it just did not post. It was stuck on the DRAM debug LED. Half an hour later and some tryling later i had to go somewhere. When i returned and tryed to turn the PC on, it just worked again. But from this point on it would sometimes outright completly freeze and sometimes not boot at all. The problem seem to get worse and currently i can't get it to post.

No POST after updating to windows 11 Decided to update to windows 11. When the update was finished installing, it prompted me to restart my PC, when I restarted it, it wouldn’t boot. I tried power cycling, clearing CMOS, flashing bios, nothing works. Have a green BOOT light on my motherboard. Before I updated the bios, the motherboard lights and light strips connected worked but after the bios flash, no lights or connected lights on the motherboard work besides the debug lights.

Computer won’t post at all. VGA LED is on and won’t go away. Computer was running fine until I cleaned it a few weeks ago and didn’t use it for about another week. When I tried to boot it, the system wouldn’t post. I have tried unplugging everything from the system and replugging which includes: two hard drives, an SSD, 2 system fans, CPU fan, front panel connector, CPU power, motherboard power, VGA power, HD audio, and still, no post.(I kept the CPU and NVME SSD in). I have tried two other video cards as well which includes my old MSI VENTUS 2060 6GB and my first R7 250 series. I have cleared the CMOS several times and I have even changed the 2032 battery.

Recently I updated my desktop to Windows 11 and this has exacerbated an existing issue with the machine. Occasionally when restarting, most often while applying updates, the computer will lock up just before POST and be stuck in this state until I force a shutdown. This same behavior happens if I attempt to power on shortly (within about 30 minutes) of a shutdown. When the PC boots with the BIOS in safe mode after the force shutdown it will boot without issue. It will also boot without issue after resetting the BIOS or simply saving and exiting after entering the BIOS from the safe mode boot. The computer also simply boots if I've left it to sit overnight after a shutdown. I shutdown my PC for the night once I've finished and it nearly always (99%of the time) boots right up so long as it's had time to "settle." About the only thing I can think of is that the motherboard is getting on in age and may need replacing but it seems to do just fine and hasn't given me any sign other than this issue that it could be failing.

The MSI one displayed for a sec but we missed bios and turned it off only for vga led to turn on. Same problem I had on the first board. The first board which the initial crash happened on first lit up on VGA and after hours of trouble shooting it went to boot. We tried with one ram, reset the cmos, tried hdmi on the first board. We moved everything over to the new board and same problem VGA. Pretty bummed out, we’re gonna try to trouble shoot again tomorrow but it’s not the gpu or mobo, I doubt it’s the cpu because it’s brand new and worked fine. Maybe it’s the psu but everything lights up all the fans spin and rgbs light up. Any help would be really appreciated.
