Graphics (video) driver is corrupted or could be related to it.
Start here:  http://h10025.www1.hp.com/ewfrf/wc/product?product=3316440&lc=en&cc=us&dlc=en&task=&lang=en&cc=us
Go to Software & Driver download, select your OS ( is it Vista?)
There's only 1 graphics driver for Vista:   NVIDIA GeForce Go 6100 VGA Driver
