Hi - I have just built a new i7 920 for a mate, he does graphic work so he needed XP 32 bit OS so as to be compatible with his current software(he will upgrade in the near future).
I used a Gigabyte EX58-UD3R board with 6GB of PC3 12800 OCZ Gold memory, a Zalman 750Watt PSU, CPU is i7 920 with standard cooler, 7200rpm Western Digital Cabiar drive, LG Dual layer +/- burner and Quadro 4850 graphics.
My problem is that the system starts up and seemed to run fine but then simply would reboot. It stays running fine in bios, and I have tried a Windows repair and a full fresh re-image. These haven't worked, the system kept running fine whilst it was loading the OS, then when I loaded all the drivers all was well, but then it crashed and restarts when Windows is simply starting and running for a minute or a few seconds, or before it even fully starts. The OS is Service Pack 3......
Pls note, it is not blue screening, it's as if some one has hit the reset button....
Am I missing something important about compatability of the OS here with the i7 ??? pls help - desperate to get this fixed asap!
