Desktop randomly shuts off

[gmaesplayer]

Hey guys~

The other day I decided to clean my computer, and so I got out the canned air and a brush and got the dust out. Then, I took it back upstairs and downloaded some programs. However, as I was installing Tor all of a sudden my computer started shutting out randomly. It would show "No Signal" on both monitors, but the LED's inside the case were still on and the fans started going max speed. Tried turning it off and back on, and then it worked fine...that is until a few minutes later when the same problem happened again. Not sure what is wrong, everything should be fine...I tried starting up a game and the game worked fine until the computer shut off. Any more info needed? Also, any ideas on what happened?

Are you sure that all the power cables are connected correctly. Maybe you pulled one off while cleaning.

It sounds like it has something to do with your graphics card.
