Random restart @ XP x64

[xtraLONG]

Hi all! Recently i bought a 3700+, Asrock dual sata, 1gb Geil and everything works FINE but now i have a little stupid problem, sometimes i'm surfing in the internet and this ''s***'' restart, or doing anything that don't use 100% CPU, CABUM restart, but only occur 1 time per day!!
I don't understand, i allready run memtest 6h, primetime 6h, OCCT, and no error at all!
I play CSS for several hours no restart, play GT Legend no restart!

The message is this: The computer has rebooted from a bugcheck. The bugcheck was: 0x000000be (0xfffffadfe1d70720, 0x00000000d8086001, 0xfffffadfe1483e60, 0x000000000000000b). A dump was saved in: C:\WINDOWS\Minidump\Mini042806-01.dmp.

Any solution?
Thx in advance

According to this:

The bugcheck is caused by a driver trying to write to read-only memory. Since you're running XP64 the most obvious thing to do would be to verify that ALL your drivers are indeed 64-bit compatible.
