Problem: After a fresh install of a Dell Optiplex workstation, the performance of the mouse and keyboard significantly deteriorated. Right mouse clicking on anything would sometimes take seconds for the complete menu to appear. Also, when typing the characters would fall behind my actual typing. At first I thought it was a video card issue so tried new drivers and different cards without any success.
Solution: Was very close to reinstalling everything from scratch so I tried one more thing. Went into the BIOS and reset everything to factory defaults. That worked! This is a solution that might work for you. If that didnâ€™t work for you, what did?
