Alright... Recently my office got brand new Windows 7 computers, Dell computers. Ever since I got mine, it's been randomly shutting down for no reason. The computer screen goes blank for about a minute or two and then it shuts down fully. It doesn't give a warning or a reason why this is happening, and my computer is the only one of 15 that's doing it. I only work four hours a day there and I'm the person who gets the least hours. I had the IT guy look at it and he supposedly fixed it. It worked fine for about a week, then it started shutting down on it's own again. I don't think it's the power cables, I checked the back of my computer and screen and both seemed fine. I also noticed the IT moved the computer back there also. Anyone have any idea what the hell's going on with it? I am not going to any new sites that I did before we did the transfer.
