High CPU usage forces other interrupt requests to the back burner. input devices such as keyboard and mouse get low priority. You can probably look for some unneeded services or startup items to free up some CPU cycles. I'd look specifically for services that might activate at intervals such as to check your email, perform updates, etc. You can view the task manager during idle times to see what might start using the CPU occasionally.
There are many definitions to keyboard lags so I will specify and be more specific.
When I am playing ANY game on my computer, or things that run the CPU at 100% anything (including the mouse) has a delayed reaction, then once it does press the button it seems to hold it in for a period of time, such as 4 ? 5 seconds.
Let me tell you, I have done everything I can. I am running out of ideas. The last thing I can think of is going on every single computer help forum I know and posting this question.
I DID have ATI Tray Tools, A program that is an alternative to ATI?s Catalyst Control Center. I do have both of them running. I also recently (due to reading some threads) uninstalled ATI Tray Tools. Problem still persists. I have reinstalled my Keyboard drivers, mouse drivers, video drivers, and reset ATI Catalyst to factoring settings, I?ve turned off the AGP speed (just to see what would happen) and it still persists.
Now you probably are saying ?AGP? How old is this computer?? The specifications of this computer are listed below:
Microsoft Windows XP
Service Pack 3
