Re: XFX 260 GTX XXX Fan issue at boot. Is it broken?
After rereading Your post I think it's not that the system is restarting 3 times. It's solely the videocard restarting three times.
Again: It's like - onomatopoeia:
wwwhhew- 2 sec silence - wwwhhew - 2 sec -- wwwhhew. After that everything works.
But my 7800 GTX has been much louder, so maybe the fan is not spinning at 100%.
