I did my first build about 9 months back and have tried a ton of different fixes for a problem i have been having since day one, my computer freezes after a little while when I play videos fullscreen and when I play games. Sometimes it will work fine for hours or even days without a problem, but other times it will freeze everytime i open a video and full screen it, be it on hulu or with vlc. At first I thought it was he operating system, I tried xp, ubuntu, and now i am using windows 7, it has happened on all of them. I thought it was the drivers for my graphics cards so I made sure they were all updated, I thought there might be a cooling problem so i got a huge cpu fan and my case has 5 fans, I got a new hard drive. I think the problem is either with the graphics cards themselves or with the RAM, iv run memtest84 and its come up with nothing, im running it again and im gonna run orthos. I want to be sure that it is a problem that can only be fixed by replacing the graphics cards before i drop $200 or more on a new one. Windows says that there is a video hardware error. When it freezes the screen doesn't go black, everything just stops. Also happens during file conversions occasionally.
