ok a couple months ago i stepped up my system to a 3.4 northwood, it was running awesome at 3.8GHz but i needed a couple more dvd-roms, so i upgraded my HD's to sata. ever since i did i havent been able to overclock. i go into bios bump up the fsb, reboot and it starts to load, recognizes all the dvd-roms, but doesnt recognize the HD's at all, so obviously it doesnt boot windows because its not detecting the drives, but when i go back into bios and set it back to stock speed, everything is recognized. i just got done updating the bios again and try it all again, but still same problem. anyone that can help me? this is really getting irritating
