I still haven't been able to get my new system running. I have eliminated everything except for the processor. The computer turns on, I can go into the bios and stuff but as soon as it trys to load windows right where the windows logo would show up the computer reboots. I have tried 3 kinds of ram of different manufacturers and speeds, PCI-E video card and onboard video, 3 motherboards, and 2 hard drives that both load windows fine on my other computer and they all have had the same problem. I have a great power supply and the temps aren't getting hot so could it be a bad processor or something with it being dual core? Its a used D805 that I bought until my E6600 gets here.
