Not sure how to explain this but my other laptop just started acting funny. You can not type from keyboard and the cursor is racing at great speed.

If you click on windows icon on bottom left the cursor is going really fast and clicking in box doesn't stop it. Also the program buttons if you higlight them flashing really fast.  If highlight icons in bottom left hand corner it flashes between them at great speed from one side to the other and back again.

Can still use mouse to run some programs but when bring up internet goes into full screen mode, can't see minimise/maximise buttuns etc at the top of screen.

It did this for first time on Saturday after working normally for 3 hours. I turned off and on, took out battery etc didn't help. On Sunday it worked normally for a while then same problem. Yesterday problem from when turn on.
