Yesterday, I was playing a game on my computer. After I exited, I got a blue screen. The message had like 5 paragraphs, and it lasted like 3 dang lousy seconds. But I managed to get "Problem with video card or something, to prevent any harm, windows is shutting down. if this is your first-" That's all I got. This is my second blue screen. The first one was a few months ago. My computer used to make humming noises, but I was able to clean some dust by the fan on the outside, and it stopped. What I think I should do, is buy a can of air cleaner, take off the computer cover, spray a few times, and take a paper towel or Q-tips or something, and clean the parts that the can can't get. And then buy some dust covers. is there anything else I should do, or anything I just said I shouldn't do? What I think happened, is that the computer over heated, dust got inside over time, and made it worse because of the dust. This place is pretty dusty. I have been using the plastic it came with as dust covers, but there's a couple holes in it. I'm going to be buying some soon. Please respond, and gimme some advice. thanks.

you can use hair dryer (without hot air) to take away the dust. Take your PC outside and do it. Make sure you put a pencil inside each fan before blowing on it. Because the fan might break if its turned by high pressure air. Leave the lid of the computer away and try it. If it crashes, it might not be the heating after all. Update your graphic card drivers. Update your game
