    did u replace the heatsink on your cpu ? if you did, try re-seating it, and making sure you have a nice thin even layer of thermal paste on there, not too much, not too little.

    did u try again? lol... not imply you are as silly as me... but i thought i reseated my heatsink... (twice lol) correctly, and it was still a little off, I had VERY high temps.

    Can you get into your bios and monitor your @ idle temps?

    It might be a power issue. Either the PSU doesn't have enough juice or it is failing. When lights dim and the fan slows down and the rest, that implies low power to me. Although 1000W is a lot, for 2 GTX 280 cards it might not be enough depending on the power supply. In looking at the recommended power supplies for 2 GTX 280s in SLI at the Nvidia website (click here), 1000W is the minimum. Ordinarily, it might be enough but the fact remains that you are having a problem.

    well thanks for all your help but i have just found out that my cpu was trying to overclock itself : S scary or what i have anti spyware antivirus and 4 firewalls so it wasnt a virus or a hack or it could just be that i have crap thermal compound but everything seems to be running fine
