Pc won't work after cmos reset
Pc won't work after cmos reset
I understand this thread is likely from earlier, but the links I found are from 2008. I’m not sure if overclocking fits the right category, but it seems closest.
I removed the CMOS using the pins and since then nothing worked — no display, drives spin up, fans run. I tried connecting the motherboard to a breadboard without RAM or GPU, and even after removing the battery for about 30 minutes before reinserting it, there was still no success.
Here are the specs I can see:
Mb gigabyte GA 78GB S2 (rev1.2)
CPU and FX 8320? It’s an 8-core processor
GPU: ASUS GTX 770
RAM: balisticX Sport 16GB
And a Corsair CX600M
I’ve owned this PC for over two years, built it myself as my first build, and never had issues. The only time I reset the CMOS was when I attempted an overclock, but received a boot message stating the MB couldn’t handle it.
I understand this discussion is from a different time, but the ones I found are from 2008. I’m not sure if overclocking fits the right category, though it seems closest to what you’re describing.
I reset my CMOS using the pins, but nothing has worked since then. Peripherals won’t display, the drives spin up, and all fans operate. I’ve tried connecting the motherboard to a breadboard without RAM or GPU.
I removed the power beforehand, not the battery, because I thought you didn’t need it. After about 30 minutes I reinserted the battery and still had no success.
The components I can confirm are:
- MB gigabyte GA 78lmt S2 (rev1.2)
- CPU and FX 8320 – it’s an 8-core processor
- GPU: ASUS GTX 770
- RAM: balisticX Sport 16GB
- Corsair CX600M
I’ve owned this PC for over two years, built it myself as my first build, and never faced issues. The only time I reset CMOS was when I attempted an overclock but received a boot message stating the MB couldn’t handle it. It was underclocking that caused the system to fail.
Here’s a video I posted on YouTube showing me trying to shut down the system: https://youtu.be/ry-Zc8gUo-Y
When removing the battery, take it out for 10 seconds, put it back in, then reset CMOS. Make sure everything is unplugged during this process and avoid working on carpet.
I've attempted that.. I've returned to breadboarding... everything is missing from the case. I have a test setup on the case switches and a mb speaker. There are no Beebs with or without RAM in every configuration. I don't see it being PSU-related, as the whole system worked fine this morning. I just wanted to reset the BIOS so it wasn't underclocking. I'm assuming the MB is toasting, so I'll leave the battery out for a few hours before reinserting it.

I'm guessing it just toasted the mb I'm going to leave the battery out for a few hours before putting it back in.
I would check my 2 x 4 pin and 24 pin connections. If a flux is laying around i would check the power the psu is putting out.
Consider swapping the battery, as I experienced the same issue recently—my motherboard's battery failed.
Ordered a battery just in case, and by checking the PSU connections do you mean to inspect them or actually verify the voltage? I don't have the tools, and I know it was working perfectly this morning.
I considered another issue. Over the past days, my PC has been crashing while playing games. I thought it was due to overheating, so I cleaned out the fans and removed dust this morning. There was a lot of dust inside. I also reset the CMOS at the same time. Now I’m questioning if my PSU was the cause of these crashes or reboots.

There was a lot of debris inside. I also reset the CMOS at the same time. Now I’m wondering if the PSU was the cause of the crashes or if it was something else. Did the PSU make unusual sounds? Also, did you reposition the CMOS pin back to its default position and ensure all connections from the PSU to the motherboard are secure?
No unusual sounds, just a black screen and reboot. It didn’t bother much because it takes around 30 seconds to boot and about an hour to rejoin a game, making it more of a hassle. There are only two pins on my motherboard—just need to connect them together?
