Hi everyone! So, I changed my components to a new case, and when I turned the pc on it was boot looping. I saw it was an orange led, I thought it was a RAM issue. Took one stick out, leaving only a stick on the slot farther from the CPU, and the system booted up no problem. Thought it was issue with the RAM stick I took off, so I tried swapping them, and the system booted up as well. Placed both sticks back in, not in dual channel, so side-by-side, and system booted up too... Only when in dual channel it does not boot. After all this, I tried to clear CMOS. This is what I did: Turn PSU off and unpluged power cord, and every other thing plugged to the pc. Removed the CMOS battery from the motherboard and shorted the 2 pins that are related to the clear CMOS, according to the boards manual. Holded the power btn for 1 min. Then waited 10 mins and plugged everything up, and inserted the battery. Turned pc on and still found it boot looping, or powering on but not showing anything on screen, and displaying the orange led... What am I missing here?

Hello all! I recently got a used Gigabyte mATX h110m-a motherboard off eBay to start my own dedicated linux server. I already had an i5 7400 laying around, and found it useful for such an occasion. I ordered some cheap ram from crucial and a corsair psu (cv series), both of which seem to work fine. The motherboard arrived today, and I checked to see if everything was working before putting into the case. However, I ran into an issue where the fans would power on, but there would be no display output. This would happen repeatedly until I turned off the power supply. After replacing the CMOS battery, and resetting it, I ran into the same issue. I suspect that the motherboard may be to blame, but I did not want to jump to conclusions yet. The CPU is known to be working, I took it out of an old PC we used for the business and kept it for personal use. Any ideas on what I could do to solve this issue?

Laptop : HP omen 15 Dh0138TX Okay so an extended cut of what happened. I was playing a game on my laptop called The Ascent, ran fine at 80+fps. No issues. Did the same last night, no issue. After playing the game for a while, I shut it down, opened up opera and started to watch some videos on YouTube. While I was watching videos my laptop just suddenly turned off. Not like a proper shutdown, but just a tak and boom, no light, no display. When I pushed the power button, no response, the battery charging light wasn't even starting up, the laptop was... Dead sort of. I looked up a few articles, I disconnected the battery, tried just ac power. No luck. Did the reverse, just the battery. No luck. Then I did that power button holding thing for 1 minute and then plugged in ac, no luck. Then I just kept the laptop as it is, went to sleep. Woke up like 3 hours later and now it's runs fine again??? It showed a CMOS checksum error 502 on the start, but told me to just reboot the computer. I did. And I am not getting that error anymore. Now the laptop runs fine on battery and on AC power. What exactly happened here? And should I be worried that it might happen again in the future? Thanks for the help in advance! -
when i turn on the computer, the press f1 shows up, then i configure the bios and unplug and re-plug my pc(drain the power on the PSU capacitors as well) when i turn it on again still shows the press f1 tried *check and reseat cmos reset pin *replace new battery *reseat ram *reset bios *reseat power connectors still not working tried *bios flash *bios reprogram *bios reprogram using external flasher (CH341A programmer) *change bios chip this is no software fix, only hardware can fix this, either replacing a chip or something i have a air solder station here so i can do a bit of smd rework if needed i dont have or cant find any free schematics and soldering is only my hobby, i just need guide on how to fix this stubborn thing -
Hey LTT Forums ! So i need to replace the battery on the motherboard I am thinking of ordering these - > Toshiba CR2032 Battery Are these safe for the motherboard CMOS ? would be great if you can advise thanks ! -
Hi everyone. Due to the new update of the valorant anti cheat, a friend of mine needed to enable tpm 2.0 and secure boot, once the computer restarted it showed black screen and no POST, so we tried to unplug the cable from the power, turn off the power supply from the switch, remove the CMOS battery for 30 seconds and put it back, once restarted nothing has changed. So we tried to remove the battery for about 30 minutes and reset the CMOS from the clr_cmos jumper. Always black screen. Any type of help is appreciated.

So today (5mins ago) I started one of my pcs and it didnt do anything, I pressed the power button and nothing, unplugged the power cable, waited 10 seconds plugged it back and nothing. Then cleared CMOS and it booted. MB: Asus P6T SE CPU: I7-920 2.67Ghz @ 3.8Ghz RAM: 4x4Gb DDR3 1600Mhz Yesterday I tried to set the Uncore Clock a bit higher than double the Ram speed (since someone said on a forum that he got more performance with setting it much higher (but it was a 4. gen I7)) and it corrupted the BIOS. Not sure how but it booted to "Boot Block Compatible version ....." and I couldnt do anything, I shorted the CMOS pins to reset BIOS and it worked. After that I set the Uncore Clock to Auto, since I dont want to kill this PC. So, anyone knows whats happening? Am I killing the BIOS chip or the CPU? But to me this seems a software issue because I can fix it with a CMOS reset. But im not sure if this will do that every single day.

So About a week or two ago, I realized My computer booted straight up to windows, No bios, no boot logo, nothing. Also I realized the time was keep resetting after I turn off my computer, so I took out the CMOS battery and tested it, and it still has a pretty good charge on it. So my question is why in the world is my computer showing signs of a dead CMOS, when it really isn't dead??? Please help some one xP

Hey guys I really need some help I moved my pc In to a new case and now my motherboard has the boot and vga lights on for about a minute and then they shut off case fans run but gpu wont turn on and the fans don't either I took it apart to clean and added more thermal paste after I removed the old thermal paste I used a non conductive paste (tm30) and sometimes the other lights turn on such as ram and cpu and other times they all turn on is this a motherboard issue or power supply everything worked before I set it up in a new case I plan on resetting the cmos when I get home I added pictures any help would be appreciated

Hi All, I finally decided to take the leap into overclocking today, and it hasn’t gone well to say the least. I used 1usmus’ DRAM calculator to come up with some RAM timings and voltages. Unfortunately, after plugging these into my BIOS, my system got stuck on the MOBO logo screen and failed to progress to booting. To fix the issue, I force powered off the system by holding the power button, unplugged it, and cleared the CMOS by jumping the clear CMOS pins. I was able to get back into BIOS and revert my changes. On my next attempt, I adjusted some timings and upped the SOC voltage to 1.1V. This time, on powering up, my system did not output any video signal and did not reach the MOBO logo screen. I noticed a small amber light on the MOBO, which I assumed was indicating another RAM issue. Planning to try again, I powered off the system and re-jumped the clear CMOS pins. This time though, the system did not reboot, and I still receive no video output from my graphics card. The RAM and graphics card light up normally and the fans spin. There is no amber light on the MOBO. This is where things get more weird. Oddly, when I tried to force power off the system by holding the power button, the system does not shut off. Instead the power button starts flashing until I release it. The system will only power off when I switch off the PSU or pull the plug out of the wall. I’ve tried cleaning the CMOS several times now, to no avail. I’ve also reseated the RAM and attempted to boot with only one stick. Does anyone have experience with something like this? I’m fairly sure the CMOS clearing is not the issue, given that it worked the first time. Could there be damage to the system hardware? How might I go about determining if that’s the case? Thanks for any help in advance!

Ok so I have had my pc for quite some time, and it never has any problems. Sometimes on games such as Fishing Planet or Train Sim World 2, the whole thing shuts off. Today, on train sim world 2 it shut off and would not post until I cleared CMOS. What could cause this?

Hey guys. I've been having this problem ever since I got my Pc and it happens at least once a month. i press the power button on my pc case and it won't turn on. So I have to unplug the pc, take the CMOS out and put it back in, then if I turn on the PC it turns on and boots up normally. I don't really know what the problem is and i hope you guys could help me out because I know there are a lot of people who are WAY smarter than me when it comes to PC's. My PC specs are 3900X with the stock cooler, RTX 2070 super from EVGA, 32 GB of G Skill Trident Z DDR4 ram, 500 GB NVME SSD and a 1 TB SSD. My motherboard is a Aorus B550 Master. -
So a while ago there was a black out after the blackout when I turned on my computer it lit up the tower RGB and the fans started spinning at max. But the monitors and the keyboard aren't working. I was told to take out the CMOS battery and put it back and that worked for the several next blackouts ( yea they happen fairly regularly here). Today it happened again but when I took out the battery and put it back it nothing got fixed. I took a CMOS battery from my old rig. (Same battery) and replaced it it still didn't work. Any idea what's wrong? Should I try to get a new battery just incase both of them are dead? Also the pc doesn't post even without the battery in.

So my old pc is a kid from 2013... it's a basic basic thing which I had assembled(not exactly) 'cause I wanted a reliable machine... something that was not as unstable as Vista or 2000 Me... anyways... that dude has a basic h61 chipset motherboard and a stock pentium g2010 processor(I didn't need more than that back then)... I've used two operating systems on that machine... it originally had windows 7 and after about 3 years, I had to replace it with windows 8.1(it was not lookin' good) in 2018, I started experience something strange... the screen(and the cpu and literally everything) would freeze, all at the same time and the screen would show nothing but different colors(such as red, white or blue) and as I Saud before during that time the entire thing would be completely unresponsive...and believe it or not, this happened even at idle.... it was frustrating... so few months back, I asked a computer guy to scrape off the 8.1 and restore it with windows 7 repairing the disastrous freezing thing at the same time... he did as I asked him to... he said that he cleared and restored the bios(that was quite unsuspecting) but I literally didn't see how that could help... and that problem returned once again, creating major instability in my life(that was too drastic) to this day, even though I have a new friend (with i5 10600K), I still need a reliable thing and everyone knows that nothing can be more reliable than an old school windows 7 pc... I think I have explained myself enough... please enlighten me on this matter

I put together a budget system for very little money and everything worked out quite well, but whenever I wanted to restart the computer, I only got a black picture, but all the fans were turning and I could even blindly use the keyboard and mouse to use. After I shut down the PC using the off button in the front panel and switched it on, everything went back to normal. I was also able to shut it down and start it again as normal. I thought it wasn't a problem, but you have to restart the PC for certain games, a normal shutdown and start was not enough. So my friend came up with the idea to reset the bios above you CMOS batteries. We did this, the computer started normally, but Windows just didn't work (after I had to select the boot device again), the screen stayed black and the DRAM led lights up red. I have already tried to put the two RAM sticks in all possible positions in the 4 slots, but nothing happens, the LED is always red and there is no picture, I can't even go to the BIOS. The mem OK! Button does nothing. I really need help! My hardware parts are: Intel Core i5 3570k ASUS H77V-LE Kingston DDR3 1333mhz RAM Radeon r9 280X (Asus design) Samsung QVO 1TB Corsair 220T -
Hi all I've been wondering about something with the CMOS battery and with resetting CMOS, if a PC have issues and so on... I've tried two times now with my own system, when I turn on my PC, all fans spin up, GPU fans aswell, RGB lights up, you know, the PC's powers on but no POST. Then what I did was to reset CMOS by removing it from the motherboard for either a couple of minutes, and/or pressing the power button while the battery is removed. But this didn't not work. What ended up working, both times, was starting my PC WITHOUT the CMOS battery installed - instant POST. Afterwards I just power off my PC normally, reinstall CMOS battery and then my PC turns on normally - POSTs and everything. Can anyone here explain to me what the difference was between resetting CMOS and not having the CMOS battery installed? Should both equal the same result? Faulty CMOS battery? Faulty motherboard? -
Need help with itx build. Recently transferred my PC from a mid tower to itx build. Only thing that was changed from my previous build was my motherboard from an MSI B550 Tomahawk to ASUS B550i-strix and the case. I am having a very interesting issue. When enabling DOCP to get my Geil ram to run at 3600 mghz everything seems to be fine and the system runs ok for the rest of the night. Then the next day when I try to boot I get a black screen, pc lights up keyboard and mouse light up, however no signal to monitor. The DRAM error light on the mobo lights up as well. In order to fix the problem I clear the cmos. This problem has repeated itself many times and I have not been able to replicate it aside from trying to turn my pc on the next day. I tried turning off the pc unplugging the psu and turning it back on, it boots perfectly fine. Only when I leave it overnight does this problem come up. I tried lowering the RAM speed to 3200 mghz and the problem came up again. The only time it has not come up is when I run the ram at default speeds 2133 mghz. I have also tried updating the BIOS to the latest version and it did not fix the problem. I do not believe it is faulty ram since the ram worked fine in my previous build. This problem has been very difficult to figure out the solution to as I do not know how to replicate the problem. Any help is appreciated. Also not sure if this is related at all. But when we first assembled it and tried to get it to post, I plugged my ps4 controller into the bios flashback usb port and the system did not post and we had to clear the cmos. Doubt this is related at all but wanted to throw it in there. Not sure what is causing this problem. (Mobo, RAM, SSD, PSU, CASE?)

Bought another CR2032 battery, it was stable for a day or 2 and today i mean a few hours ago its started to happen again. Every time i clear the cmos, after a min to 10. it shuts down (as if the motherboard loses all power). Switched the ram to the other slot (just a single dim) and cmos'ed and it worked for an hour, played games and suddenly while i was writing- it dies. -
Hey there! First post here, massively urgent issue. - Just got a new EVGA 3080 XC3 Ultra with (I believe) a factory overclock on it. - was replacing a GTX 1080 Founders edition which worked fine - GA-AX370-Gaming K7 (rev. 1.0) had bios f2 on it when I installed the new GPU - would not boot, gave me error 05 and then 05 after a n attempted power cycle and CMOS clear (via the button). - Cleared CMOS w/ the button (I dont have a jumper), Flashed the BIOS, and proceeded to try and do all the updates and follow given instructions provided by Gigabyte to make sure it was being done correct. - As I did this, I realized the pattern that it would not let me in unless I cleared the CMOS, power cycled, switched to backup BIOS (which gave me errors still), and flashed the bios. EACH TIME I shut it down. - I decided to update the BIOS, and followed the instructions, but no dice. Still getting 00 and 05 errors mixed with the occasional AA an AB (8?) or A0 which I could get it to boot. - XMP is not working at all, and old gpu wont get it to post either. - I am on my backup bios now, its F10. I think if I shut it down I will find myself doing the same cycle again. The default settings are loaded on both, but even that seems to be an issue.

When is it nec4ssary or important to clear the CMOS? Before or after a build? I know It helps when playing around with memory, but Is that when manually adjusting timings? -

Overclocking went wrong, my CMOS doesn’t want to reset
TraffyLawOP posted a topic in Troubleshooting
So, yesterday I decided to overclock my i7 3770k. It just went wrong because I changed the core ratio to 4,7, and ofc it was too much. The first time it shut down I just removed the cmos battery for a few minutes and everything was fine. Then I decided to use only 4,2 GHz on my cores. But it seemed to be still too much because it shut down again. But this time it wouldn’t boot up. After trying many times and clearing the jumper, removing cmos, ram, etc... it worked again but without the battery in. So today when I put my battery back in again ( I guess the cmos battery changed to over clock settings again) it wouldn’t boot up. I checked everything and I’m 100% nothing is broken or damaged. I always changed things with the psu power off, left hours ( more than 5) to try again and reset the cmos. But the pc just runs normally without recognizing the monitor/keyboard/mouse. So I can’t get to the bios and change it again. I really tried everything (using cpu only, 1 ram at a time, with/without battery, with/ without jumper) and nothing seems to work. I know for a fact that nothing is broken because yesterday after 3 hours leaving it with no power it worked and I even played Warzone. The problem was the reset didn’t save because it had no battery cmos, so as soon as I put it l, it overclocked again... The last thing I can try is just leaving it till tomorrow and try again... my pc: -HP mobo z75 Pegatron -rtx 3060 ti -i7 3770k -12gb ram
