After trying to overclock my cpu, my pc booted but was coming up with 2ghz when it started at 3.2ghz and i was aiming for 3.6, after pressing the restart button after a successful launch, all I can get to now is the mobo making a long bleeping sound, then proceeding to boot again and do the same, my motherboards beep definitions tell me its a gpu problem if this occurs but my gpu is correctly inserted and plugged in, any suggestions?
