I've had very good luck doing this with CPU's that displayed "overclocking symptoms". Although doesn't directly address the overclock issue but may be of some help. Probably won't though if the problem is game-specific. If it is computer-wide, it may be of help.

DISCLAIMER: Write down / record *all* your BIOS settings before you do this.

Generally, you can test the overclocking theory with almost all MB's manufactured in the Last 4 years or so by going into the BIOS and loading the "Fail-Safe Settings". If the stuff works then, try going back in and putting your BIOS settings back until it fails. Then you should have a better ideas as to the culprit.
