After I did a clean install of Windows 7 Ultimate, the system runs slow. It takes a long time to install programs & runs slugish. I have a new Seagate 1.5 terabyte hard drive, Intel q9400, 4 gigs Patriot Viper memory, Zotac GeForce 480 video card, X-Fi Falaity Titainium sound card, Pioneer Blue ray burner, Sony dvdrw, Thermaltake Spedo full tower case. The temperatures are fine. If you have any questions just ask.
