PC overheated, now won't boot

November 27, 2010 at 11:55:45
Specs: XP Pro SP 3, Pentium IV 3.2GHZ/3GB
My PC overheated from the heat of the wood stove and suddenly shut down. The cooling fans were running very fast for several minutes before shut down. On my first boot attempt, nothing happened, blank screen. Power was on and case and CPU fans working. I unplugged the PC from the wall, pressed the power button several times, and cleared the CMOS by removing the battery. Now it boots to the BIOS, but cannot load the configuration screen. It just hangs in BIOS for a few minutes and then the PC shuts down.

I was able to get through BIOS, but got CMOS checksum bad, overclocking failure, and CPU overtemp error messages. Then it booted to Windows. Everything normal for a few minutes, then PC suddenly shut down.

You've got to get the PC away from the stove & give it a chance to cool down. Also, by resetting the BIOS, you lost any custom settings you may have configured & are now running with defaults. Deafults are NOT good performance settings & should only be used as a starting point.

You need to do more than just move away from the stove. The CPU is overheating even in BIOS so it is likely the heatsink is clogged up with accumulated dust. You may also need to remove the heatsink, clean off old thermal compound from it & CPU and apply new thermal compound.

I let things cool down overnight before attempting anything. PC is 12+ ft from stove, but gets quite hot 80 or so in the room. I put the BIOS back to custom settings, and now PC been running fine all day. However, during subsequent boot attempts system hangs and shuts down at various points of BIOS load.

Thanks for your help.

I clear the heat sink of dust regularly. I'll plan on applying new thermal compound. I'm scratching my head because it ran fine all day, but now shuts down during BIOS load. Looks like the initial overheat/shutdown may have cooked the compound.

Thanks for your help.
