Hi guys, I recently bought a new motherboard and new ram and a new CPU all compatible as far as I know. However the hard drive I am using is an old 300gb hard drive. It's transfer cable was a 1.5 gb/ps sata cable. However since the new motherboard only has a 3 gb and 6 gb sata cable, I plugged the 6 gb one into the hard drive. I also tested the 3 gb one and I got the following problem. It would start up and I could get into the bios, but when I want to start windows, it will say "starting windows" for a couple seconds, then restart the computer. Someone told me that if I put a clean version of windows on it that my problem should be fixed. Can anyone verify that please? Here are my specs: Asus p8z68 m-pro Intel i7 3770k Corsair vengeance 4x4gb ram Maxtor 300gb hard drive 350 watt power supply Any help would be greatly appreciated. Thanks!
