Hi! I got this new pre-made computer from a Norwegian store some weeks ago. Ever since I got this computer, it's been having this issue about 1-3 times every day, at seemingly random times, but I do see some strange behaviours about when it happens. - It has yet to happen while I'm not playing World of Warcraft. - When it does happen, it tends to happen again shortly after the first crash, up to 3 times. I can even start my computer at noon, and it might start crashing around 3 in the night. To give a bit more of a detailed word about what this crash involves, what happens is that the screen goes black. The lights on the screen which indicates if the screen is connected to the computer or not starts to blink, to signalize that it is no longer connected to the computer. In addition, sometimes, I can hear in my headphones that the audio might halt. To get out of the crash, I simply have to manually turn off the computer and turn it back on. Some details about my system that might be involved in the issue: Windows Vista SP1 Intel Core2 Quad CPU Q6600 2.40 GHz NVIDIA GeForce 8800 GT Would appreciate some help to solve this most annoying problem, thanks in advance.
