Win 7 Freezes After Startup Okay so I when I startup Windows I am able to login but after about 3-10 min it will just lock up and freeze and I am forced to restart by pressing the button. This has just started happening recently about 3 weeks after I put my new RAM in. (Went from 2gb to 4gb) Windows Vista works PERFECTLY fine. Specs: OS: Dual Boot Win Vista Ultimate x64 + Win 7 Ultimate x64 (Both Full Retail) Proccesor: 3Ghz Intel Dual Core Ram: OCZ Reaper 8500 DDr2 2x2gb sticks. Graphics Card: Nvidia 8800 GTS HDD 1x500 GB 7200 RPM with Win Vista + 1x1TB with Win 7 Anyhelp would be Greatly Appreciated!!!
