Computer Freezes After Few Seconds Of Any Game

[RyanDangerRogers]

I recently bought a new graphics card and it was working fine and everything, then I upgraded my Computer case and now when I open up any game the computer stops working. The screens (I have dual Monitors) both blink and then sometimes look all pixelated or striped, then there is a deep buzzing noise and everything goes black. My friend said It might be the cpu overheating because the first few time it did this it made the beeping noise after about a minute. Please help.

Have you downloaded and installed the latest drivers? What PSU do you have? It sounds like it may be due to not enough power being delivered to your GPU. Also, you can use CPU-Z or HW Monitor to check your temps.

I have downloaded the latest drivers, but I can try reinstalling them because my AMD Catalyst Control Center has been acting a little weird. This is the power supply I have: http://www.newegg.com/Product/Product.aspx?Item=9SIA4H81E87130&cm_re=modx_stream_pro-_-9SIA4H81E87130-_-Product
