After cleaning & blowing out all the dust etc, my old faithful pc now shuts down usually while XP (32) is loading. I tried entering the bios to look around for something wrong.....but after a minute or two it shuts down while in bios. So I don't think it's OS related.
I started looking for loose connections etc. The only thing I could find that was loose is my LGA 775 stock fan/heatsink. I removed it, cleaned off the old paste etc, re-installed with new thermo paste.
But after trying for hours....I simply cannot get the stock fan/heatsink to fit tight with no movement.
I got it better than it was, however the pc still shuts down during boot up. I tried pressing down firmly on the cpu fan/heatsink while booting. PRESTO! it boots up fine. I kept it running several minutes, and all worked normaly....until I released pressure on the cpu fan/heatsink,......it only lasted for about 2 minutes after releasing the pressure, before shutting down.
Am I right in assuming I need to get an aftermarket cpu cooler? One that has a better installation method than the stock cooler?
