Mouse/Keyboard Delay In Games

Well ill start out by saying that, because its the first assumption, i dont have any viruses on my computer or spyware. I do advanced virus/spyware removal on computers almost daily. Dont mean to sound cocky (not sure how to word it otherwise O_o) just want to avoid the most common respose, "you have viruses." lol

Well whenever i go and play a game such as Counter-Strike: Source, Halo2, Battlefield 2142, Crysis, or FEAR, the mouse is always delayed about half a second. So i move the mouse and half a second later, the screen finally moves. On Halo2 its mouse and keyboard. I had Windows XP Pro SP3 installed before Vista Ultimate 32bit without this issue. The only game that seems to run good on my computer is World of Warcraft

Things ive tried:

• Changing Maximum Pre-Rendered Frames to anything below 3
• forceing Trilinear Optimization on
• Forceing Treaded Optimization on
• Forceing Tripple Buffering on
• Forceing vertical sync on and off
• Changing the Vista theme to the old school 2000 theme
• Turning the Sidebar Off
• Changing Startup to Diagnostic
• Changing to only a single display
• hours and hours of looking online and trial and error

System Specs:
Intel Core2Duo E6550 2.33Ghz
2Gb DDR800 Memory
Geforce 7300GS 256Mb with two monitors
Saitek Eclipse keyboard
Microsoft IntelliMouse Explorer 2.0 Wireless

Hi Beware,

Are both your keyboard and mouse wireless?

Just the mouse is wireless. Keyboard is USB.

CounterStrike and all FPS games set the Mouse-Updaterate very high and this will cause problems with wireless because it cant update the computer fast enough for the game requirement, Theres nothing you or anyone can do about that problem except use a Hard-Wired mouse & keyboard...

The other problems you suggested can be caused by having too high video settings for your graphics card or the wrong game video settings (low FPS), Internet lag and system resource lag...

Can you upload a screenshot of GPUZ and CPUZ?
