I recently upgraded my CPU using a Powerleap PL-P4/N socket 423 to 478 adapter with an intel Pentium 4 2.8 Ghz with 400Mhz FSB (SL7EY).

motherboard : Asus P4T-M
Geforce Ti4200
on board sound
768mb PC800 RDRAM (samsung)

when I run Windows XP the computer keeps resetting spontaneously. but always within about 10mins. I have Windows ME running on a second hard disk, it runs this okay but cannot do Direct 3d and I get errors when trying to run games to do with the graphics, which all worked fine with my old CPU.

I was told the adapter does not have a pin for CPU temp so I disabled this in the bios (temp monitor) the bios reports a cpu temp of 59C I have been running the machine with the side off and an extra fan. I also told windows XP not to reset automatically on errors, but it still resets.

not sure what to do and would appreciate any help.

Thanks.
