[SOLVED] Graphics card crashing in-game

[sloppymuffin]

After about 30 min in furmark or a variable amount of time in games my computer will start producing graphics artifacts then completely crash. Max gpu temp was 78°c, max cpu temp was 67°c. I've RMAed the gpu twice and the PSU once each time I replaced the gpu it would play games for hours fine then start having issues a week or 2 after being installed.

Use either Task Manager or Resource Monitor to observe system performance when you start gaming.

Just leave the window open but dragged to one side.

You can also use Reliability History and Event Viewer to look for error codes and warnings that precede or correspond with the times of the crashes.

Total up the wattage demands of all system components. Use the high end wattage if a wattage range is provided.

Once totaled add 25%. How close is that final wattage to 800?
