Client Side CPU Lag for mouse and keyboard

[Gunjin]

Hey community,
Sorry if an issue like this has been posted already, I looked around and couldn't find anything yet. Feel free to link me of course.

The issue:
I have not been able to play Counter Strike efficiently as of late; I now have very noticeable CPU lag. My mouse has a drag to it, and my keyboard responds this way too. The response time isn't sharp like it used to be.

My basic spec:
AMD Athlon 7750 Dual-Core 2.7ghz
4 GB RAM
GIGABYTE Motherboard (I'll dig out the model number if necessary--it does have on-board by the way(if that helps))
GeForce 250 GTS 1 GB
Windows XP SP3

I've done all the necessary tweaks I could think of, and still no progression in game-play. I had no issues whatsoever when I had an AMD Sempron 1.8ghz, and Radeon 9800 XT back in the day, until I saw some news about the newer drivers creating problems with CS. I reverted to drivers from the early 2000's and I was set. This was also a reason why I moved to GeForce. And now its just as bad.

Thanks for everything

Re: Client Side CPU Lag for mouse and keyboard

Usually, if a game starts to lag but was running fine before, you either recently got some sort of virus that is slowing everything down, or a lot of dust has accumulated in your PC. You should try opening up your computer and cleaning the dust.
How bad is your framerate? (type cl_showfps 1 in the console and check it)
