Alright, I have the q6600 GO, and a P35-S3L Mobo. I"ve been researching Overclocking it for a while and I just recently got a Arctic Freezer 7 HSF. I overclocked my cpu to 3.2Ghz 356x9 and had all the settings right and was rock solid in Prime. I decided to go a little further. IT wouldn't get past the windows loading window so i bumped up the CPU voltage a little more and then all the sudden it doesn't recognize either of my hard drives or my cdrom. It says "DISK BOOT FAILER Please insert boot disk and press ENTER". I"ve tried putting the win xp cd in and nothing happens cause it doesn't even reconize the CDROM, i've reset all the defaults in Bios as well. Im lost and very frustrated, if anyone has any idea what I could do please let me know. Thanks
