How can I play standard PC games in 3D?

How to fix pc screen to play downloaded games?

• So lately i have been trying to play downloaded games like left4dead or something like that. But when i try to open the game then my pc screen will turn crazy i will see like different colors every time but i still hear the music of the game. So my first thought was that my pc couldnt handle the graphics but the 2nd time i tried to play maplestory and it wouldnt even show those graphics!?!? and i mean maplestory doesnt even have nice graphics, its not even 3D lol. So about my pc its not even that old. My parents bought it last year and it was all new. Its windows 7. This is all i know about the pc the brand is a ACER I am sorry about the lack of inofrmation i have but i hope you guys can help me.

• Answer:

  There could be a problem with the video card. I had a problem like this one time. Turned out the fan on the card was jammed with dust. Since games will require more from the card, it will cause more heat output. If the fan is not working correctly you will have issues and will most likely have to replace the card.
