Ok, so i've built this decent computer for about $500. I OC'ed the CPU (celeron D @ 3.06ghz) to 4.22ghz with no problems. The FSB was 731mhz. I decided to turn the FSB up to 735 (only a 4mhz increase). So i did. I saved the changes and re-started. The first time, the BIOS just froze after telling me my CPU speed / specs. The second time, it just says "Nvidia 650i Ultra" in its big, shiny letters. It doesnt do anything more. I beleive that to re-set the BIOS, i remove the little battery thing, right? any help appreciated :D *ITS A HOME BUILD - NOT A DELL*
