Random Crashing, Need help..

[CrockSmoke]

Ok, so about 2 hours ago I was playing M&B Warband, and listening to some music. My computer then randomly shut down as I tabbed out, black screen, just figured my windows crapped out or whatever. Power still running, fans still going, just black screen. So I shut it down by holding down power button, and restart the computer. Computer boots up into the "Windows did not shut down properly" prompt, which I select "Start Windows normally". After which it starts booting windows. A second or so later my screen is all red and yellow, maybe some blue. It was like a mess of blocks. So I shut it down again and let it cool off. Start it about 5 minutes later to no input detected through to the monitor.

It was pretty dusty so i figured I'd just clean it out and get dust out. Put everything back in, dust free, and restart. Now I'm getting the same issue. Did another shut down and reboot it a bit later. Now the computer wont even start. But it is getting power to the GPU because the PCI-E plugs are lit up green like normal. Is my GPU fried? Did I kill my computer?

It sure sounds like the Video card is tired. but it could also be the MB PCIE socket. Have you tried the Vid card in another PCIE slot? according to the specs for the board, it says that it has 2x16 and 2x4. It might be an idea to try another slot.
When you were cleaning the machine out, did you check to see if the video card fan/s worked?
Are any of the components in warranty? if so, you might be able to get a replacement?
Try those checks first and while you are at it, try loading the machine with 1 memory chip at a time and see if you memory is causing you grief?

Hope that helps
