I have a custom built gaming computer and it has been freezing up on me. It is only like a month old and I have had to reset it a # of times because it will lock the pc up to the point that I cant even get into task manager. Also GTA 4 glitches out real bad even on the lowest graphic settings. I KNOW that my computer exceeds the requirements for all my games but it just isn't performing. I tried reinstalling game, running game in compatible mode, defraging hard drive, and updates. Nothing helped at all. Friend suggested reinstalling windows but that is going to be my last resort. don't want to have to take all my music and crap off of it. If anyone has an idea it would be greatly appreciated.
