Hi, I have a 3 year old HP P6310y desktop. The PC often freezes when playing games and often blue screens. Then while watching Youtube it has minor freezing, almost never happens. I've checked the RAM and the RAM is good. I took off the cover of the PC and put a little AC fan to cool it. I quickly noticed improvement, surfing the web doesn't freeze along with Youtube but I still have an issue with playing games. SEEMS AS IF IT'S AN OVER-HEATING ISSUE. After playing games the PC starts to lag then freezes following up with a blue screen (freezing and blue screen happens RANDOMLY). Please help me solve this problem, here are my Specs: Athlon II X4 CPU, no GPU (Took out my graphics card thinking it was the potential freezing, but it wasn't), 6GB RAM, Pegatron MOBO, and a 450 watt PSU. NOTE: This problem occurred for 8 months. ///Thanks in advance!
