I'm trying to build a PC with the newly bought Abit KV7, Athlon Barton core CPU with 333Mhz FSB, and 512M Kbyte DDR PC2100 (266Mhz) memory. After I hooked them altogether, the monitor didn't show anything. Neither did I hear of one short beep. When the display card was removed, I did hear one long beep and two short beeps. What will be the cause? Is it because the frequency of my DDR (266Mhz) doesn't match the frequency of CPU (333Mhz FSB)? 
Thanks a lot.
