please help... intel cpu + winXP
I'm looking for help troubleshooting an odd situation.
OS: winXP pro (legal copy)
main board: ASUS p4c800 deluxe
cpu: intel 3.0ghz, hyperthread, 800mhz fsb socket 478
psu: thermaltake silent purepower 480W
memory: 1gb kingmax (2x512mb)
hdd: 120gb maxtor SATA
video: geforce 6800 GT
sound: sb live 5.1
I power up computer, and when it starts loading winxp - ie blue bar cycling - it will sometimes turn itself off. Sometimes. If not, it will turn off within about 2 minutes of use. I mean turn itself off as in it reached out and unplugged itself. I have tried a friend's 2.0ghz (no HT) cpu and it works just fine. I have downclocked my cpu to about 2.0ghz, and this seems to work, as long as I turn off hyperthreading.
This computer used to work perfectly for over a year, and now this. I have had my MB and CPU replaced through ASUS and Intel's warranty, tried different video cards, power supplies, even cdroms and hdds, and still cant get the 3.0ghz I paid for to work again - with WinXP Pro.
One more thing, I write this from my computer - fully functioning at 3.0 with HT enabled, with firefox and Fedora Core 4 installed. Seems like some sort of software issue with XP, an update bug maybe??
Has anyone else had this problem? I have heard of the hyperthread issue, which is why the 1st thing I tried was turning it off. This still wont explain why it worked for over 1 year then stopped. I'm really stuck on what to do next.
Any help or link(s) to help would be much appreciated.
