My computer freezes up when I am playing games. Sometimes the screen just locks and I have to shut the computer down and restart. Other times the screen becomes discolored with lines and I get a loud buzz from the speakers. I have also got a blue screen that says it is doing a "file dump". I referred the problem to Dell and they said it was a problem with my graphics card driver and they uninstalled and reinstalled the card and updated the drivers; however, I continue to have this problem. This has also occurred when in Email and when working with other files, but mostly when playing games. I browzed for answers and downloaded "pc health boost" but they wanted me to pay for the fix and I did not even know if they were a scam or not. Any help will be greatly appreciated.
I am attaching my dxdiag file.
