Well, I had a thread with this problem before, but i have an update and would like to start a new thread. The deal is that when I try to boot into any os or try to install a new os, the computer locks somewhere during the process. So I was told that it was the hard drive from a tech guy, so i RMAed my hard drive only to get it and it did the same thing. So now, im not sure what the problem is. It has to be something hardware related, right? The hard drive is new. I tried setting the BIOS defaults. What else is there to do? and how can i find out if it is a hardware problem?
