HPET is high precision event timer. It's the new timer they've been using since vista.

Go in to your bios (restart comp and hit DEL repeatedly) and enable HPET if it isn't already and make sure it's set to x64.

If you're still having lag problems go to your STEAM library. Right click COD black ops and go to properties. Hit the local files tab and hit the "Defragment Cache Files" button. You can do this for any STEAM game and it might clear up some lag issues.
