So I bought a new computer, high end. AMD 6 core, Nvidia gtx 470, 8gb 1600 RAM, Thermaltake case w/ liquid cooling ..... Among other things (I don't know where to copy/paste all my system info from and I don't feel like typing all of it (other specs available on request)). So my PROBLEM is that occasionally, actually very seldom at all, I'll try to open a program and it will open fine except the screen will go black and I'll have to force SHUTDOWN. It happened 2 or 3 times when I launched the game Elder Scrolls IV Oblivion, once when I pressed ctrl+alt+delete to get to task manager (there weren't any problems at the time, I just wanted to check my CPU performance). Then once when I was on the phone with Microsoft Tech Support. That time the guy was using remote access to VIEW my computer from where he was and right when I clicked the "Start Sharing" button it went black. I restarted and did the process again and it worked fine but clicking the button made my whole desktop the remote access black desktop (which is normal). It changed what the screen looked like, for lack of a better word. So I'm guessing that it's a graphical error related to my video card but I'm worried that if I send my computer in for repair then they won't be able to recreate the problem. If anyone knows of this problem and can be like "oh yeah, that happens because of this and that." Or "Yeah that's called the ... whatever."  That would be awesome. I just want to be able to reference something, like the name of a problem or be able to state the problem in a way where the tech support at the company that I'm gonna send it back to knows what to look for and how to find the problem other than just trying a bunch of irrelevant fixes that don't work and charging me for shipping. Any help would be appreciated. Thanks in advance.
