A8N SLI Premium Mobo (939 socket 64bit amd cpu)
4 x 512 corsair ram
1 x 8800gt
1 x 680 watt power supply
For a while it kept shutting itself down, sometimes a few seconds after i turned it on or a few minutes from desktop. I tried a number of things to fix it and in the end dropped it in at a local pc shop. They said the 8800gt was overheating and causing it to shut down, it so happens that i have another 8800gt so installed that and it turned on fine, got to playing Modern Warfare 2 for 30 mins or so then switched it off and went to work. When i came home and switched it back on it shut down after 1-3 seconds and kept doing it. I opened the case and put my pedestal fan on facing the mobo and it turned on all the way to desktop and then as soon as i loaded MW2 it shut off, second time around it shut off after using firefox for 1 minute.
Seems that it must be CPU overheating but i thought i might post just in case anyone else has come across this before and had any fresh ideas.
Cheers in advance
