Issue Overclocking causes system failure and motherboard display as dead.
Issue Overclocking causes system failure and motherboard display as dead.
I slightly increased the overclock settings for my CPU, RAM, and GPU, along with adjusting the voltage for each part. I followed the recommended steps when overclocking. After saving and exiting, the system attempted to boot multiple times—everything lit up and fans started spinning—but it kept showing a black screen whenever I pressed save or exit from BIOS. Each failure led to shutdown, then another attempt until I flipped the power switch. I looked into the issue and decided to reinstall the CMOS battery. After removing it for about 20 seconds and reinserting, the motherboard appeared completely dead—no fans, not even CPU fans. The only sign of life was the GPU. What should I do? Could this mean the system is down? Maybe I accidentally shorted it; I wasn’t grounded, though I didn’t touch the motherboard except for the CMOS battery. I’m unsure what to do next. Please advise, thank you for your help.
Initially, the solution was to reset the BIOS, which required removing the CMOS battery. To properly reset the BIOS settings, you need to remove the battery for a minimum of 5 to 10 minutes, not just 20 seconds. Are you certain you placed it correctly? You might try removing it again and wait at least 10 minutes, also unplugging the power cable from the PSU. Additionally, try closing the power from behind and press the power button for a few seconds.
So here’s an update if someone else encounters the same issue in this thread. I swapped the battery completely to a new one, which somehow caused the board to display vital signs and all the fans are spinning. The only remaining clear issue is that there’s still a black screen, maybe the GPU failed by all the OCs.
The exact amount of voltage increase needed is unclear. From what I know, a black screen and only fans spinning suggest damaged capacitors on the motherboard. A black screen can occur when BIOS settings fail, but it's often fixable by removing the battery for 30-60 seconds or shorting two pins for 15 seconds if the motherboard supports it. If these steps don't resolve the issue, it's possible something has been damaged. Does your motherboard have Debug LEDs?
Latest update, the fix came when I swapped out the battery entirely—maybe it resolved an issue like shorting or breaking it during installation. Damaged capacitors might be involved; I’ll check that and see if the motherboard is okay.
