tried this but no good.Check if turning off the event viewer logging helps like it did with similar keyboard problems in GTA IV
yep I recently bought an SSD so windows is fairly newly installed.have you tried it with everything stock (no overclock)?
I just fired call of duty up and mapped walk, strafe and use to my mouse and guess what, smooth as silk. strafing while looking around and clicking use key like crazy and its fine. only the keyboard does it. what the hell?
