Awhile back i had this same post about my computer randomly crashing. I somehow managed to fix it. I installed a xaser 11 fan and decreased core voltage by .1 . Now though i have reformatted my comp and guess what its back!! Now im at a complete loss of what to do. The fan is still installed and running perfectly, the core voltage is still -.1 and everything else on the computer seems to be running fine. Ive also tested the ram and its fine.. Xp 2000+ 640 mb ram Samsung 52X cd-rom Lite on 52X cd-rw Xaser 11 heatsink Acoustic ede psc706 sound card Geforce fx 5200 ultra Biostar m7vib motherboard and i think thats it... The only thing taking up my usb slots is a cable modem but ive had this problem before i got cable.

Its a 400 watt automatic fan power supply... But if i somehow fixed the problem before, i dont think it oculd have been power supply..

Does this happen even before you put any programs on it?

Yea it has once in awhile frozen on start up... it freezes randomly at different intervals of time. Sometimes within 5 minutes other times after 30 min

What I mean is that you said you reformated, I was wondering if you had installed any programs other than XP itself? Also I have had ram that was not compatable with other ram but it didn't show up on the ram test. I don't know how many banks of ram you have it might be one 512 and one 128 or it might be two 256 and one 128, try taking out one at a time and see if that helps.

In response to my earlier post about a power supply. There is no way to test a power supply. You will have to get another one to replace it with. Just because a power supply puts out voltage and seems normal does not mean that it is normal. You might have a ground loop or some other weird thing going on in there that you will not see any sign of but it will affect the operation. In the analogue days if you had a bad ground on a power supply the worst you would get is a 60 HZ hum. This is digital now and if you get a bad ground there is no telling what the results will be. To make a long story short,I stand by my earlier post. Bite the bullet and replace the PS. That is the only way you can eliminate that component. Beleive me I have been there several times. I keep a known good PS around for servicing purposes.
