For the last two weeks I have not played Blockland or other computer games. Finally it's fixed.
The first week my family tried figuring out what was wrong by themselves, which they had no idea what they were doing.
Finally we bring it to this awsome computer guy who makes custom computers and works on computers. He figures out that the graphics card we had burned out from me playing games like Blockland, TF2, Half-Life, etc. So I have it back now.
Discuss computer problems you've had.
