Problem with mouse lag

[Techhobo]

I am having problems with mouse lag. The computer will work perfectly sometimes and then it will starting lagging with the touch pad mouse. At first an external mouse would work completely fine and now it is lagging with that every now and then(not as bad). When the lag is bad it will be on and off for 10 seconds at a time making the computer almost impossible to use. I contacted HP support and they had me perform a BIOS update. Initially I thought it was a hardware problem because the external mouse worked fine but now there is issues with it as well.
