I hava a P3 500mHz with 512Mb Ram and two 40Gb HDD Running WinXP Home. In the last few days I have had a problem with the OS Freezing, no mouse, Keyboard or CTRL/ALT/DEL response. At first this would happen almost straight away and on reset it will freeze solid on the XP load-up screen.
Once I leave the PC for a while (4-6hrs) it will reboot normally, and if I switch off as many running processes as possible it will run OK for 2-3 hours before becoming jerky and then freezing completely again. The PSU Fan appears to be running but I don't know about the CPU Fan.
Normally the processor runs at pretty much 100% as I run [email protected] in the background so I am assuming it is either the processor or it's fan/heatsink that is the problem.
Would this behavior be seen if that were the case?
number 1, stop running seti at home for a while (theres nothing out there anyway) then strip your machine right back, hardware and software, clean everthing again hardware and software, then buildit all ack up slowly bit by bit. buy a new power supply as your system is old and your present one is probably getting tired.
