Hello, I have a rather unusual problem I replaced a GTX 1650 with an RX 6700xt. After replacing the card I uninstalled the nvidia drivers and then installed the drivers for the amd card and updated the drivers on the chipset but had problems with games having slight stutters every few seconds. I decided to repeat the process of uninstalling and then installing the drivers. This fixed the problem but some games still had the stutter problem (I didn't have them with 1650). So I decided to remove and insert the card from the slot. After doing this, the computer turned on, but gave no picture (the VGA light was on). So I decided to remove one of the two RAM sticks and the comp booted up normally. After turning off the computer again, I put the other ram stick back in. The computer booted up without any problems. Being convinced that I would solve this by completely uninstalling windows I did so. This did not help. There was still the same problem, that when I remove the card and put it back in, it would not boot up on two ram sticks. After booting on one stick, turning off and inserting the other it works normally as it did before reinstalling windows I would like to add that the bios was updated before I started the replacement process. The Last thing I did was resetting the bios(didn't help). In general after reseating gpu pc turns on but no display. It only turns on after removing ram stick from second slot. After that It boots normally. After shutting down and putting in the second stick everything works just fine. It ONLY happens after gpu reseat. Specs: MOBO: B450 aorus elite v2 CPU: R5 3600 RAM 2x16: Corsair vengance pro rgb 3200mhz PSU: Be quiet straight Power 11 650w The rx 6700xt is from sapphire

Hi there. Maybe the community can help with my problem. I had a working PC Specs: Asrock B550m Pro4 (BIOS v 2.50), AMD Ryzen 5 5600G, Corsair Vengeance LPX 16GB DDR4 (2x8GB) 3200, Crucial P3 SSD 1TB M.2 NVMe PCI Express 3.0, Nvidia GTX 1050ti. I wanted to remove the dedicated GPU and use the CPU's one. I Downloaded DDU, rebooted to safe mode, nuked nvidias drivers and selected shut down afterwards for GPU removal. When removed the GPU, plugged DP cable to MOBO and pressed power btn, MOBO's BOOT red led is on and system cannot boot not even into BIOS settings. Removed the m.2, same. Plugged in GPU again, the same. Any Ideas???

Hi there! This is my first post on the forum. I’ve got a HP Elitebook 2530p (i know, it’s very old but for my laptop needs it’s enough) that’s been acting very strange in the last months. Sometimes, when I boot the machine up, after the HP bios screen, the OS doesn’t start up (I’ve got Ubuntu 19.10 on it) and it stays on a black screen. After I force shutdown a couple of times and try to start it again it boots up. BUT another problem it’s when I try to restart it or wake up from standby it gives me a ram error (the caps lock and block num flash on the “touchbar”), but I’ve already tried with known good ram sticks from other machines and it always gives me the same problem. Did somebody have the same problem? If yes, you know how to solve it? (Trashing the laptop is not a accepted fix ?)

Hi I'm New here. Hi there, I have been experiencing an increasingly serious bootup problem with my Lenovo G500 laptop. Both the hard disk and the DVD drive are not showing up in BIOS, so it appears that there aren't any bootable devices. But other times they appear out of thin air, and the computer just boots up and Windows starts. Unfortunately, this happens only after 1-2 hours of switching it on and off, and this tiresome ritual is getting longer every time. . Notebook: Lenovo G500 (i7-3520m, 16 GB ddr3 ram, Samsung 500 GB SSD 750 EVO) Bought in early 2014. Condition: Thermal paste was applied about 1 year ago. There are no heat issues. What I have tried so far: I tested the computer with different hard disks, but nothing changed. I tried to use another Lenovo power adapter, but nothing changed. I run the Windows memory diagnostic (when successfully booted). I tried inserting a disc into the DVD drive, it spins, but it didn't appear in Windows. USB boot doesn't work, but it never worked. What I haven't tried so far: Lenovo System Recovery, but I want to leave this option as a last resort. My questions are: What could be the root cause of my problem? What can I do? What else to try? Any guidance and help would be appreciated. Thanks in advance for your answers

Hello, after changing thermal paste on my ASUS fx505dy, Windows 10 seems to not load anymore! It would turn on but after the boot screen which says ASUS, a black screen appears and disk light seems to not blink anymore I suspect that I may have damaged a component while cleaning the thermal paste off with a cloth, and it's probably the GPU, since booting with safe mode (which I assume uses the integrated GPU) works fine. Steps I've taken: rechecking and recleaning thermal paste going into safe mode and turning off all non Microsoft services troubleshooting with system diagnostics (shutting down again and again to get the checking for errors screen). using a restore point sfc/scannow and dism check integrity and chkdsk /f /x unplugging all USB devices as well as plugging them all in connected PC to another monitor what I am looking into is trying to boot with just the internal GPU from the cpu; maybe a way to disable the dedicated gpu help would be appreciated! thanks!

Hi guys and girls, I have just bought an intel q9550 (cost me £10 from a friend) to replace an e5500 in my friends google docs machine. However when I inserted the new processor and booted the machine, and it powered on but no video signal. The old e5500 works fine, and the q9550 was tested a few days ago on my friends machine and was ago working fine. Upon inspection of the cpu socket I noticed some small anomalies (picture attached) to some of the pins, is it possible that these pins are damaged and the e5500 doesn't use them and the q9500 does. And if not, what else apart from broken cpu could be causing this issue. Here's the cpu compatablity list for this computer model, so I don't think it's that. http://global.shuttle.com/news/productsSupportList?productId=1382

Hey, I just bought a new pc case and replaced everything from the old one to the new one. So if have done this before and it is still the same hardware so it all worked before. But this time when it supposed to load windows it gives me a blue screen with the usual thing and it says critical service failed. Does anyone now how to fix this or is there something broken when it does that?

Hi guys well i am very very upset cause i havent been able to figure out what is going on with my laptop. I own 2 Lenovo L420 they are exactly alikenothing is different i5-2520M at 2.5ghz (3.0 ghz TB) 4 gb ddr3 1333mhz (2 x2gb Samsung) 256gb toshiba 2.5 hard drive. Windows 8.1 single language Ok so both have the same OS, the same specs and everything. One day one of the laptops stopped working. I mean it boots but it wont get past windows logo. I tried everything. I reinstalled windows even tried with linux ubuntu. It installs then it wont get past the logo(windows or linux) and it stays there. I switched memories from pc to pc to see if maybe there was an error. nothing. I bought a new hard drive a SSD 200gb EVO from samsung. Same thing. I changed the cpu even added some thermal paste and checked on temps. Everything worked on first pc but not on the other one. I am starting to think that maybe the mobo is not working. I dont really know what to do.

I built my first PC and (I made a topic on this yesterday) it won't boot up completely. The power supply (CX600M) turns on, then turns off, then turns on again. This happens over and over. First, we thought the power supply was bad, so we got another one, but that still didn't fix the problem. The monitor isn't getting a signal when plugged up to the computer, and the LED on the power button turns off, then on, then off again, just like the power supply. And everything was plugged into a surge protector. And we checked the voltage and that was right as well. What's the problem? We check all the cables, reseated the RAM, and changed the power supply. What's the problem? Do I need a new motherboard? Because when we jump start the power supply without plugging it into the mobo, the fan stays on.

I had a Seagate Firecuda SSHD because I wanted the boot speeds of a SSD, but wanted the storage of a regular HDD. It was great at first, but it only saves the most frequently used programs in its SSD portion, so after playing multiple games etc, it felt like my Windows boot times were starting to creep back towards regular HDD speeds. So I bit the bullet and bought a 128GB ADATA SSD I think I made a mistake when installing my OS onto my SSD. I left my old SSHD as is, because there was a lot of important stuff on there that I didn't feel like copying over and just wanted it all to be saved. However, while preserving my old files - I neglected the fact that Windows was on my old SSHD while installing it onto my new SSD. From what I can tell, I boot from my SSD - however, when I boot I'm greeted with a blue screen asking if I want to boot from "volume 1 or volume 3" Volume 1 boots in just fine, and volume 3 doesn't - which I'm assuming is my old SSHD. However, when in bios and I set my boot priority to my adata ssd and disable the other one, I fail to boot and am asked to please insert a bootable device. If I have it set to boot from the SSHD, it boots and I'm able to boot back into Volume 1. To test out the issue I'm having, I completely unplugged my old SSHD and unfortunately was unable to boot at all with it unplugged. However, I'm still relatively confident that "volume 1" is my SSD, because when I go to my %SystemRoot% folder, it indeed takes me to my C drive which is my SSD, whereas my SSHD is my E drive. Can anyone give me any input regarding this issue? It certainly "feels" like I'm booting off my SSD, windows loads in about 3-5 seconds minus the time it takes to get to the screen asking which volume I want to boot from, but I am just completely unable to boot without the old drive plugged in which is making me question if I'm actually booting from that instead... Any help at all would be appreciated. Oh, and it's Windows 10 Home 64 bit by the way.

Hey community! After formatting two of my Seagate hard drives in my PC to raid 1, my computer started having problems. I have a 960 Evo, and the boots were quick with the hdds unformatted, but after using windows to format them to raid 1, my computer took longer to boot and wouldn't shut down. I eventually had to hold the power button for a few seconds to get it to turn off. Help!!!

Hey guys im trying to boot my pic for the first time but I keep on getting the message bootmgr is missing if you need my computer specs just ask

Acer Predator G3-710 GTX 970 8GB Ram i7-6700 unknown motherboard Okay here's the deal: I tried dual booting windows 10 and Linux Ubuntu, when something went wrong; i couldn't go back to windows 10, so i thought: "Why not just format my ssd and my hdd and make a bootable usb drive. (I was aware that i was going to loose all my data)" However i think i formatted it in the wrong format since i haven't been able to boot it from a bootable usb drive. What I've tried: Switching from UEFI to Legacy Multiple ways of making the USB bootable Turning off safe boot and fast boot Where I am now: Whenever i'm trying to boot from either the SSD, the HDD and my SanDisk bootable USB, all that happens is a blinking cursor on a black screen.

Alright Ladies and Gents.... im a software and coding virgin to an extreme degree... (as a example i have updated my bios once since i built my pc in Nov of 2018) Im having issues booting into windows because windows defender software is corrupted somehow.... whats the fix for this? fresh windows install? id REALLY rather not do that... if i need to i really dont want to loose all the data on my PC and have to re-download everything... particularly password, OBS settings.. etc.

I have a ho pavilion, model number in the title. It came with a m.2 with windows 10 pro installed. There is a spare slot inside the laptop for another drive. But the open ribbon cable sad hdd. Will an ssd work in that? I installed a 860 evo v-nand 500gb ssd with the proper ribbon cable L23889-001. Installed it reboot and I’m met with black screen, cannot enter bios and 5 quick blinks and four rapid from the caps lock. I reset the cmos ( windows key+b+power) and reboot everything works fine. I have files on the drive windows sees it in device manager. But I have to rest cmos ever my time I reboot. Any ideas?

I helped a friend updating his work PC/casual gaming and we went for a Ryzen 5 3600, MSI B450 Pro Carbon AC (which has BIOS flash without a CPU installed to update it), RX580 and a 1TB PCI-E SSD. The only things that were re-used from his previous build (I5-6600 / R9 ...380 something?) are the case, ram (DDR4-2400 FuryX) and PSU (CX750M). All components re-used were working. Done building it, I got a bad feeling immediately as no power was actually going through the PSU to any other component. Had to take out and replug all cables to make it "boot" (black screen, but needed to flash the bios) and also had to remove the secondary CPU 4-pin cable completely or it would start. After flashing the bios the PC booted and windows was installed just fine. However, during the setup and from there on, sometimes (even during the reboots of the installer) the "EZ Debug" lights on the motherboard start to signal problems with CPU/VGA (cycling through them also, sometimes, but it's 8/10 times the CPU that keeps being undetected) and only after you forcing it to shutdown it can boot again correctly. Tried to run a few tests around in windows after installing the drivers and pretty much everything works correctly once it boots.. So I wonder were the problem might be. Faulty motherboard? Faulty PSU? Both? Any ideas?

Im having a problem, so my pc is one month old and I know it’s should be working properly...every time I turn it off and then turn it on can’t get monitor to display....this is my second time getting this. First time I resetted CMOS and it worked fine then but I want it to work with no hardware resetting...is possible that PSU is not working properly?

Hi, I have a custom built nas, but after a power loss it doesn’t boot anymore, when I connect it up to vga I see a screen that displays an error, but all the letters are scrambled and I can’t read it. 59345087620__955EF93B-A282-484A-B052-F4E34242D3A1.MOV

Hi all, Pleaseeeeee help I have an HP Z230 workstation that was given to me and for the life of me I cannot find a fix for this. As soon as I turn on the computer it is stuck on the bios HP logo. I have tested the cpu and the ram and both are fine. I took the hard disk out and stuck it in another pc and it's fine. Took my existing hard disk and put it into the z230 but then the same thing happens. However, when I turn it on and for the duration of the pc being on, there are no lights on the keyboard nor can I get them on by pressing the caps lock/num lock keys. It's as if the whole computer just freezes up. Stuck a USB with windows 10 hoping it will boot but nothing happens. The cpu fan does spin and the CD drive does open and close when pressed. I just cannot get any further than the logo screen no matter what I do or press. The thing I can do is switch it off by hitting the power button. I would really appreciate any help! Thanks in advance!

Hi LTT community. I'm having an issue with my drives booting. My operating system is stored on my SSD and the SSD has been set to the #1 boot priority. However, unless I select my hard drive by using f11 to get to boot order, the display says "operating system not found. Try unplugging drives without an operating system". Yes, I have done that, no it did not work. Some important information is that I recently changed cases so as such unplugged everything including SATA cables and rebuilt. The SATA cables for the SSD and HDD are not in the same place as before but as far as I know that shouldn't have an impact. To clarify, I can use the computer, but only by selecting the HDD in boot selection. The HDD does not appear in the BIOS boot order, and the SSD registers as a hard disk, though I believe that's normal. Please let me know any ideas for a solution. Thanks

Hi guys, I recently upgraded my dad's PC from an i3 530 to an i7 860 and from a gt 730 to a EVGA gtx 570HD. Now I was trying to boot the system for the first time after the upgrade, everything seemed to work in the case (all fans blowing also from GPU an CPU, etc.), but my moniter told me that it wasn't receiving any signals from the GPU. I've tested this card in another system with the same psu and worked just fine, do you guys have any suggestions on what to do?

Hello! Im having problems installing OSX El Capitan. First of all, when I run Unibeast, It takes ages and I end up with two volumes, one called USB (The one I named in Unibeast) and "EFI". I've watched videos and read posts and no one seems to have the second one.Then, when I try to run it on the pc in clover, the apple logo appears and it loads half way and then it black screens. It's very frustrating because just a few months ago I got it to load the os and install everthing... (Then I screwed it up somehow.) I tried booting in verbose mode and took a pic, but still don't understant it.I have two drives a 500gb ssd and a 1tb hdd. Also, ive heard that it's a good idea to use a 2.0 port but my motherboard and case only have 3.0 ones. A few months back I installed linux to make sure the hardware is fine (and it is.) but after that I took the ssd and formated it on this pc. I was tupid knowing that when installing osx it formats it anyway but I have a feeling I may have formated it badly. Any Ideas?

Hi, so I recently bought a new pair of RAM sticks to add to the ones I already had installed (I had 2x4GB, now I have 4x4GB). They are not exactly the same but the computer-parts-store-guy told me that there should be no problems, and they are pretty similar: -("old") Corsair XMS3 Vengeance DDR3 PC12800/1600MHz CL9 2x4GB (CMZ8GX3M2A1600C9B) -(new) Corsair Vengeance DDR3 PC12800/1600MHz CL9 LP 2x4GB (CML8GX3M2A1600C9) So you might see they are pretty similar (same speed and class, CAS latency, size, same company, I mean the only thing that differs them exept for apperance is the "B" in the end of the product number). So I thought I simply had to put them in, and thats it, right? Full system specs: Here is when the problem starts: After installation of the new RAM sticks I Get into BIOS and check that everything looks fine, and it does, everything is as I left it and the system memory shows the correct 16 gigs. How ever when I try to boot into windows some kind of Windows repair thing comes up and tells me something along the lines of "boot failed, repair failed or needs the insert installation disk or USB key" and some options to get to the windows boot menu. I restart the PC (not following what the text on the blue background is telling me, get into BIOS and reset to default and boom - the pc boots just fine. In windows nothing seems to be wrong, the built in "troubleshooter" nor sfc /scannow nor bitdefenders registry scan thing manage to find any problems, and the same goes for me. All 16 gigs of ram are visible and usable. So the thing is I had a pretty nice OC on the CPU (4.5 GHz, +0.075 V, stable max measured temp 60 ° C (with both prime 95 and furmark running so some heat from GPU gets to the CPU cause no rear exhaust GPU; prime95 only max temp 53 ° C) The ram ran in XMP mode so that they would reach their rated speed of 1600MHz (they default to 1334MHz). I've had no system or program crashes (that could be blamed on the OC) since the first successful stress test. Now I've only managed to boot with no OC (default settings in BIOS) and XMP disabled. No OC and XMP did crash. Haven't tried OC and no XMP, it just hit me so I'll try it soon. Not having my OC does not make me happy. My original (OC) settings: (please comment if you see something you would have differently, even non problem related) So my questions are: Is this to be expected when more RAM is added? Is there something wrong with having non-identical RAM sticks/my BIOS settings/other? How should I "combat" this? Should I return the RAM sticks and get identical? Or? Something else? Please help! General tips regarding my hardware or BIOS settings are also appreciated. Thanks in advance /Rinkana (Sorry if I posted in the wrong place, new to this forum..)

I'm not sure if this is the right section to post this but I am having a lot of trouble booting up my new computer. essentially what happens is I turn it on, the LEDs and fans spin, the hard drive boots up, then after about 15 seconds it will turn off and restart again. I don't think it is a short because i have reseated the mobo among other components and i can keep the everything inside the PC running if I press the case's refresh button every few seconds. I have only tried booting it with a HDMI cable because i can't find a VGA so could this be the problem? any help would be greatly appreciated. Thanks, Hugo P.S. I have tried a few troubleshooting guides but nothing seems to have worked.
