PC fails to boot following a BIOS update attempt
I realize now that I should have let someone handle this professionally, even though I thought I was tech-savvy enough to tackle it myself. My old PC has been acting up with frequent crashes over the past two weeks. After trying various fixes, I discovered an outdated BIOS update. Once installed, the system froze during setup, but eventually I could move my mouse despite the stuttering. A restart later revealed a short beep from the motherboard, suggesting a parity circuit issue. I attempted to replace the CMOS without success, but based on what I learned, the problem likely lies with the motherboard or RAM. I’m seeking advice on whether to give up or try further repairs to avoid buying a new machine.
Usually it's recommended to refresh quite outdated motherboard BIOS updates in a specific sequence; rushing to the newest release might cause issues. However, let's assume that happened and proceed regardless. To reset CMOS correctly: disconnect power from the PC, remove the CMOS battery, keep the power button pressed for 30 seconds, swap the CMOS battery, then reconnect the power source.
