I just recently built a new computer. I have vista home premium. Vista is constantly freezing, or getting a blue screen. It runs fine for a while then freezes or blue screen. The problem report says that it is possible that it is caused by my CPU, Ram, motherboard, or PSU. How do i go about finding out the true cause of this problem. All 4 of those a brand new, and are compatible with each other. I have installed new drivers for each that has drivers. please help.
