I purchased Nvidia Geforce GTX 550Ti recently and used it for gaming using the SLI technology. It worked fine for 3 months but after that I realized that games are running on higher framerate than expected. After some days, whenever I used to press alt+tab to switch applications, I used to get an error message saying that Graphic drivers have crashed. I updated drivers in my system but it didn’t help. So I freshly installed all the drivers again but the problem persisted. But now, whenever I start any application, especially games that require graphic card, my screen goes black for few seconds and game crashes. I don’t know what is happening can anybody help me sort this problem?
