COD4 keyboard/mouse lockup

[hangwire]

Here are my specs

PSU=Corsair HX-620 watt
CPU=AMD Athlon X2 5000+ 2.6ghz(dual core)
RAM=2xCorsair XMS PC 800 DDR2(2 gigs total)
MOBO=Biostar NF520-A2 socket AM2
GPU=ATI Radeon x1650 PRO 512 RAM PCI-E
Sound=integrated
Mouse=Wireless Intellimouse Explorer 2.0(http://www.newegg.com/Product/Produc...82E16826105063)
Keyboard=This is a very old generic HP keyboard that came with a comp I bought years ago. There is no particular name for it, all I can say its a model 5181.

My problem is.......Occasionally while playing COD4 I just lock up........it isn't the comp that locks up. I simply lose control of both my keyboard and mouse. My computer continues to run fine, in fact the game keeps going. I can hear explosions,I can see other people fighting, I can lower my volume, etc. Everything works absolutely fine aside from losing complete control of the mouse and keyboard. Ctr+Alt+Del doesnt work....Alt+F4....nothing...I can't move my screen with my mouse....nothing. Since my mouse is wireless there are buttons to "connect" the mouse with its receiver, using these buttons do not fix the problem once it locks up. I just lock up and continue to run until I hit a wall and somebody runs by to shoot me. I have to use the system reset button on the front of my computer to restart the computer to get any control back. There doesn't seem to be a trigger for this.....I can't identify a pattern but it does seem to do it again in about 20-40 minutes after it happens the first time. And from there its too often to enjoy the game. This NEVER happens outside of COD4. About a month or two ago I replaced my mobo/cpu/ram/PSU with what I have now just because it was time to upgrade my hardware. The problem DID NOT start immediately, but it NEVER happened before this. Thankyou and I would really appreciate some help.

What happens when you use a wired mouse connected to the PS2 port ?

That.....actually never occured to me. I have my old wired Microsoft Explorer. I will try that if i can find its software and see what happens. Also, for the first time today it locked up and then 5-10 seconds later I regained full control, this is the first time it has fixed itself and I have changed nothing. Also, the first time this ever happened......when I rebooted my comp it was immediately stuck again. It was stuck at the windows login screen. So I shut it down, hooked up my old mouse and it worked. I then restarted again with the wireless mouse and it now just ocassionally screws up while playing COD4. Could mouse software and/or mouse software options be causing this? Its a very common mouse and I have not found anybody else with an issue anything like this.

Mouse drivers, especially wireless ones, do cause trouble.
I'm still puzzled about what's happening with you but if you just gave the mouse drivers the necessary swift kick that might account for it.
I'd check and see if there were any recent driver updates for your mouse.
