Google avails me nothing in my diligent search for a solution to this problem. Since I got my new week-old gaming PC I have been experiencing crippling freezes when I play any PC game except World of Warcraft. I have experienced these freezes in Halo 2 for Windows Vista, Crysis 2 (rare), TES IV Oblivion, Call of Duty Modern Warfare 2, and those are the only games I have played on it so far. The freezes last 30 seconds to 2 minutes and are of intermittent and seemingly random frequency during gameplay. (4-10 minutes apart) The first freeze is delayed for maybe 20 minutes after I start my first game up and then persists in its random fashion until I restart the computer. My CPU sits at 30-40 degrees C during this whole process. It is an AMD Phenom II x4 840 with stock cooler. During the freezes, Task Manager reports that the CPU is almost idle. My PSU is an adequate 500W Mushkin. It has only one 6-pin connector and my GTX 460 has two slots, so the second slot is connected to an included adapter to convert two molex to a 6-pin. I strongly suspect that the problem here is related to the PSU or graphics card. I'd really appreciate any input and would be more than happy to answer questions.
