Major Problem with all games


Aug 27, 2012
Good day to you hopefully helpful people. I don't play a whole lot of games but recently my computer has become completely useless and i can't play any games at all. Starcraft II has horrible lag issues and all other games (ie: skyrim, day z, dead island) force my monitor off and then make my computer unresponsive. I feel my computer is up to playing all the games but regardless of what the graphics settings are at they crash. Any help would be appreciated.
Computer info:
16 gbs ram
Processor AMD FX(tm)-8150 Eight-Core Processor, 3612 Mhz,
Graphics card: AMD Radeon HD 7970
Sabertooth 990fx motherboard
Install a system monitoring tool such as CPUID HWMonitor, and have a look at your system temperatures, power supply voltages and the like. Please report back so we can check for anything out of the ordinary.

Also, what power supply do you use? Have you recently made any changes to the system that may have caused this?
