Specs: Windows XP, P4 2.8HT + 2X 1G pc3200 DDR400
System was running ok before upgrading the CPU from CELERON 2.53 to P4 2.8HT on ASRock P4I65G BIOS 1.40.
After the upgrade, XP wasn't booting at all on the old OS, nothing happenned between the OS and system so I had to do a fresh install of XP sp3 + updates. I installed a ATI 9200 AIW card but removed it after the problems occured. I did a MEMtest+ for the RAM and they were ok.
The CPU temp is arouns 38c and the MB temp 60c (but can't where to tweak that). All two fans are running at 2,5000rpm.
Now, at random, the pc do this;
-starts normally but after a while (during game or installing a sofware), it reboots
-Sometimes, the pc won't boot, no power but the cpu fan is running, the power led is down and it is impossible to boot for log minutes (10 to 15)
-After few minutes, lights are back and pc starts again...

I guess its the power supply (Thermaltake2).

ps: after the first bug, I reinstalled the old CPU but same thing happenned so I putted back the new one.

Merci for your help!

I forgot to mention that after the fist CPU ugrade, I rebooted the pc which entered XP, recognized the new CPU under ACPI, installed it then rebooted but never got into XP again. Thats why I decided to reinstalled XP.

Second, when the power was down, I thought the MB was dead but lights reopened after few minutes...

"The CPU temp is arouns 38c and the MB temp 60c"
was this when you first boot??

"starts normally but after a while (during game or installing a sofware), it reboots"
maybe the temp is increasing as time goes on and, is now increasing faster.
Describe how you applied the thermal compound.

Temp are from a normal booting, after few minutes of running the pc under Speedfan. Not much programs are open, Firefox, DSL and Speedfan to test. I tested when running NFS-Porsche 2000...

The grease was apply as usual, after cleaning the cpu and the base of the fan then putting the fan over and clipping.
