Ok so I just built a PC, with an i7 950 10 ddr3 corsair a gtx 480 video card on a sabertooth x58 MB and a LSP PSU of 650 watts, all this I have it on a cooler master Haf case with 3 fans on it. My problem is that since I hooked it up, when I try to sing in into wins 7 64bit, it starts loading and then it restart by it self. I uncheck the auto restart option, I tried every ram one at a time to see if they were all fine and I even switch my video card to a different pci slot. On my BIOS I have everything on Auto, and nothing is overclocked. CPU is still running at 3.06ghz. I ran an anti virus and my hdd is fine. going insane here... PS. I am able to go in safe mode and it runs fine there, well up to its limit on that mode.
