Been having this problem a while now and can seem to solve it.
PC Reboots randomly, either when im there or overnight, nothing seems to be a particulat cause.
Its not a Toshiba PC and i dont have Lexmar Media USB which seem to be the only thing the microsoft knowledge base lead to.
If i set my PC to blue screen, its blue and blank so i cant get the info from there
Error code 100000d1, parameter1 fffff782, parameter2 00000002, parameter3 00000000, parameter4 f73b2883.

Radeon X800 GFX
Kingmax Hardcore 2x512 (new memory, same prob with the old)
Asus A7nx Deluxe 2.0 (latest bios put on but didnt help)
Loads of HD Space
All the latest drivers
On reboot the message says recovered from a serious error.
