I have been having problems with my graphics card lately. I just recently was having issues with it. I would be playing a game and everything would run great untill randomly one day, random colored squares appeared on my screen and flashed my monitor off then back on. When it flashed back on it was fine for a bit then it did it again. The next time i turned on my computer, i cheked my driver settings and it said it has stopped working, error code 43. I called geek squad, which is where my warranty is at, and took my computer in. They took the computer for 3 weeks, replaced the graphics card, and ran diagnostics. When i got it back, which was the other day, i turned on a video game. It ran fine for about five minutes then the screen turned itself off and went into power save mode. I could not turn it back on unless i restarted teh computer. After doing so i checked the driver settings again and the error code 43 was back. Anyone have an idea of what could be causing this. I have tried taking the card out, cleaning it and have followed steps that have been posted on this site for similar graphics card forums, but nothing seems to be working. Pls help.
btw sorry for the length of the post
