Okay...I was previously running a (unbeknown to me) cracked copy of Windows 7 Ultimate on my computer...had had a friend custom build it for me and that was put on there.
The computer, after about six months, began to behave very erratic-like. It would freeze me out of doing any web based download/installer, and Flash Player and such uninstalled themselves. I ran a virus scan (from 3 different programs) and they all came back clean. I figured it was that I was running a cracked copy. So I purchased and installed a clean copy of Windows Vista Home Premium SP1. Also did a full partition deletion before I did this, to kinda give the computer a fresh slate to fix whatever the issue was.
Now, it will randomly freeze every five minutes to an hour like clockwork...any ideas as to whats going on?
