so i was playing sleeping dogs the other day and my pc froze up, and then all of a sudden it started jittering and then went purple with vertical lines... it wouldnt respond, had to do a hard shutdown. pretty much any time i open up a game i get the same results... any idea what can be causing it? I did just install a cooler master hyper 212 plus, but would that have anything to do with this? everything is at stock speeds right now, (i did over clock my 6870 a bit with CCC but nothing too crazy i dont think)
I also reseated the card and memory just to make sure.
so i havent had the chance to test in another machine yet, but or some odd reason im getting terrible connection to the internet via ethernet, and yet everyone else in the house (including my macbook) are getting upwards of 20mb/s where im stuck at .3mb/s.... could this all be motherboard or psu related?
