NO SIGNAL on monitor, i tried a cold restart still nothing... i'm not sure whats going on.... it turns on but wont show anything and stays running really fast not how it was when the vista program was running.... /cry

    Sounds like main board RAM issue, try running with only 2 sticks at a time. Check your BIOS and make sure your FSB is at the right freq. (I'd guess either 266 or 333MHz) so you should be running DDR2 or 3-1066 or higher.

    Edit: oh I forgot to say "Beatch" Pff QX6850, can you buy a better cpu please. (sarcasm, jealousy and humor all for your reading pleasure)

    i don't think its a ram issue, i called eVGA and he told me i needed to update my BIOS for it to support the new QX6850 processor, anyone else have a problem like this with your 680i LT board not supporting these new quad core extremes without a Bios Flash?

    when they first come out with new processors it is not uncommon for some boards to be sold that have to have BIOS updates to run them and lots of newer BIOS updates have been coming out.

    i figured it out, turned out i did need to flash my bios, i flashed the bios with the p06 update and clocked my processor down to 1024 mhz and disabled the second two cores, core 2 and core 3, to make it run more stable, i was able to get it to boot up and flash with a floppy without having to buy a different cpu but yea, i got i all running updated and drivers installed then i clocked the cpu back up enabled the cores, hooked up my SLI and this comp friggen screams now... cod4 is amazing on it... thx for all the help :D
