USB problems in Call of Duty 4 Driving me crazy HELP!

[v3rax]

I have this chronic problem everytime I play COD4.

I am assuming it is a USB problem since my mouse and keyboard begin acting wierd.

What happens is some of my assigned keys stop working about half way through a game.

If I reconnect it fixes itself but then happens again a few minutes later.

I have tried a new mouse and keyboard, changed motherboards, reformatted, set my PCI to 100 in BIOS, reinstalled the game, and troubleshot trying to use the process of elimination till I am blue in the face.

I am totally stumped as to what this could be.

My PSU is a Galaxy 850, Mouse is Logitech G5 (USB) keyboard is Saitek USB, motherboard :Asus Maximus Formula, CPU: Q6600, VC 8800GT, Cooling is no problem and all drivers are the latest, BIOS is the latest, etc...

I have changed all my parts to different parts numerous times and still get the same problem.

Any ideas??

Operating System?
All patches for COD4 installed?

Have you tried a PS/2 Keyboard & Mouse?

I am suing XP and yes all patches have been installed.

My motherboard does not have PS/2 plugs for the mouse, only the keyboard

Are you using the Logitech software? I never install mine and my MX518 works flawlessly. People end up hating the shotgun because of me.
