Hey guys, I'm having a really annoying problem with my PC, when playing World of Warcraft, (hardly ever happens with other games) my computer simply dies, with no warnings or anything. Then after about 2 seconds it tries to start up, and makes a buzzing noise on speakers/headphones, nothing happens then it dies again after a few seconds and tries to start again, over and over. If i pull the plug for 2-3 minutes it starts normally again. Sometimes it asks me to load bios defaults or reconfigure it manually. Another thing is, it doesn't happen after a certain amount of time, sometimes it can happen in 10 min, 4 hours, or not happen at all. My PC specs are Intel Core 2 Quad Q6600 @ 2.4Ghz Asus P5QL-E ATI Radeon 4670 HD (1Gb w/ Arctic Cooing edition) Delta Electronics 250W PSU Any thoughts about what is causing this, or any suggestions. My temps are: CPU hardly reaching 60 but not going over, and GPU going to 50-55, in full load, so I don't think it's overheating. Thanks, I will really appreciate any help.
