I got a computer from a friend who said it continually crashed on him or froze. He said he was going to throw it away so I stepped in and said id take it and of course I did, due to it having substantially better hardware than my current rig(his and my specs below). The issues I had experienced when I got it was extremely similar but the main one was freezing at the bios splash screen and maybe every 10th reboot I may have been able to get through to windows where it would work fine but this was a while back so I may miss some details like whether it crashed on me or not. From what I remember it never did, anyway getting to the point. My diagnosis was that the motherboard or the bios chip[ were dead or something along those lines. I see no reason the CPU shouldn't work but I am also not an expert or have a lot of experience diagnosing PC issues. I just would like some advice on if I should put the money in to buy a motherboard to use this CPU or if I should save time and money and get better which I assume is most people's answers.
