Hey guys. I have a newly built system with an ASRock Z77 Extreme4 motherboard, i5 3570 CPU, Radeon 7870 graphics card and 8 GB of RAM. I re-used my PSU which is an OCZGSX600 (600W power supply). I am getting a strange freezing problem occasionally. However, it happens mainly when I am playing games or watching videos on Youtube. The computer will freeze up for about a second or two, the audio will skip, and then it will be fine. It will do it about 5 times, then it goes back to normal. I have all the latest drivers, and I am lost as to what is going on. I checked my CPU temps during gaming, and they are around 53 degrees Celsius on a stock cooler. The problem has occured during normal use (such as internet browsing) as well, but it isn't as common. Any ideas? Thanks.
