My motherboard, EVGA680i Premium, won't let me go beyond the introductery text when i power it up. it says keyboard error or no keyboard, then it goes on to say insert floppy and press enter. i thought it was some wires messing up so i took the whole machine apart, cleaned it and put it back together but same old problem. i even tried the keyboard on another machine and it worked fine. i thought it could also be the power supply so i bought a new one, still nothing. in any case here are the specs of the machine so you guys know what i'm working with: intel quad core 2.6ghz, 1x2 gig ram 667mhz, 512mb nVidea Graphics card, 250 gig maxtor Hdd, 160 gig maxtor Hdd, 480watts smart power supply 20amps average. Please help.
