Hi Rusher1,
Kindly let me know the operating system installed on the computer so that I can help you better.
Please check the performance of the touchpad and keyboard in Safemode with networking.
If the system has Windows 7 operating system, restart the computer and tap F8 on Dell logo and select Safemode with networking in Advanced boot menu and hit enter.
To boot the system to Safe mode in Windows 8 refer this link: http://bit.ly/PB1iP3
Awaiting your response!
