So i'm building a computer for my friend from spare parts. Just as a preliminary test, we set up an i7 920 @ stock on a MSI X58 Pro-E motherboard, with 4gb kingston ddr3 @1333mhz, and an old geforce 9600GSO. The rig is running off a Maxpower Vortec 750W psu (overkill, i know - but as i said, spare parts).
We connected one of his notebook harddrives (hitachi 5400rpm 320gb SATA2 i think) with windows 7 installed, but upon the "starting windows" screen it freezes then reboots - indefinitely. Not sure if his is 64-bit or 32, but safe-boot doesn't work either, the computer simply crashes and reboots when loading the files.
Curious, I connected one of my notebook's drives (seagate 160gb SATA2 5400rpm) with windows vista 32-bit installed. The computer booted fine, and after various cpu and gpu stress tests I concluded that the components seem to be working properly and the PSU is not faulty.
I then connected a third notebook drive of mine (not his) that had windows 7 x64 installed, but the exact same crash happened again!
So for some reason, it seems windows vista 32-bit boots fine, but both drives with windows 7 x64-bit crashes indefinitely on boot.
Any ideas?
