this computer build is atleast 2 months old computer specs mobo: Gigabyte z77x-ud3h cpu: intel i5-3570k OC at 4.2 Ghz with corsair h100i liquid cool ram: 8gb corsair vengence psu: 1250w xfx BE gpu: 2 gigabye HD 7970 OC OS: win 7 64 The problems I've been having and unable to figure out is if i was to play a game and then alt tab out of that game and open up a internet browser and go onto lets say youtube or multiple websites at one time, my computer will freeze a bit then the screen will turn black and then it will say no display is found, but the computer will still be on, only way to fix it is to restart the computer and then go on from there. This happens all the time and I've asked around and have yet to find an answer why. Ive reapplied Thermal compound onto the cpu using the pea method in the middle and ran a stress test hottest cpu will get is 80 and below but on avg use temp is around 33-40. I've checked both the GPU and they both seem to be running fine. But then again im not sure as it can be anything at this point.
