Actually it was set on "Standard" but I changed it to the "manual" and the following to "Auto"

Good heavens, your CPU is running very hot. chrisbliss has eliminated the possibility of overclocking as far as I can tell (resetting BIOS to defaults), so now you have to work on your cooling! If the PC is no longer under warranty (and if it is, you should take it back!), have a read of this article for cooling assistance. You may want to enlist the services of a technically inclined friend if you don't feel up to the tasks outlined.

I have a similar problem. PC was working fine until I relaced the CD ROM drive with a DVD ROM drive. Now I get the overclocking error and can't boot up under any mode, nor can I go back to last good configuration - just keeps trying to load the OS.

After you do the above, you should try taking out all add-on cards, ram that isn't original, and all peripherals. Then test and if stays on continue rebooting with another just "1" more thing added to mobo to find what it really is messing it up. Hope it helps.

Go here and get the latest BIOS update also.
