hey, i recently installed a new Motherboard, cpu, and video card in my computer, and didnt reformat or anything before hand. and now when i run any program, the computer freezes up completely after about 5 minutes. the motherboard is an Msi k8t neo-f2, the cpu a socket 939 winchester 3000+ amd64bit, and the video card a sapphire tech x800xl. i cant find my windows professional OS cd, so i wanna fix this without reformating if possible. im thinkin it has to do with all the old drivers interfering with the new ones and stuff like that. thanks for the advice.
