Recently my bro's computer started having problems. Errors kept popping up such as explorer or registry. So I reformatted the computer, and after I reformatted...the same errors popped up. And then it decides to shut itself down. I waited a few minutes, turned it on....errors showed up again and restarted itself. This time it turned on but a black screen with the mouse pointer. This computer is pretty old it's about 7-8 years old, I was suspecting it's too old and just about time to give up. What do you guys think?
