a disk read error !

hi yall well my problem is that i can't boot and i think it's my new motherboard
well i bought a new cpu a month ago. and it worked fine but one day when i got home and was a about to start my cpu up then this error appeers A Disk Read error occurred press Ctrl - alt - delete. at first i thought it was the hdd but i used the old floppy drive used it to run data lifeguard diagnostics that i got from westerndigital.com to see what was wrong with my hdd and it said 0000 wich means no errors so i think it's the mobo that's where i got stuck
