A couple of days ago I did a very mild overclock of my 780. It's something I'd done in the past without any incident but this time when I loaded up a game it immediately started artifacting. I set the GPU back to stock but it continued to behave strangely after that. Basically after five or so minutes in any game it would begin artifacting before crashing. When it crashed it would either freeze and eventually go back to the desktop giving a kernel mode driver error or the whole machine would actually restart. I did a clean install of the latest drivers but the problem persisted. I started the heaven unigine benchmark and monitered the temperatures as it progressed. Every time it hit 71C I would start to see artifacts and it would freeze, before eventually starting again while giving a kernel mode driver error. I was puzzled by this considering 71C is well within normal temperature operations. I check the fans were working properly and also used other software to make sure the temperatures were accurate. Not really knowing what the problem was I increased the fan curve to keep the GPU less than 71C. Anyway I started testing it on the latest call of duty and after ten minutes or so there seemed to be no problems when suddenly all power cut out and now the computer wont respond to anything. Even pressing the power button does nothing.
I've never had any problems like this before. Does anyone have any idea what may have happened?
