I have had this problem for ages now, i had to disable my graphics card on myu XP due to it continously making my monitor keep clicking as if it wanted to change resolution. Screen shot attached.
agree with that And Reinstall the Video Driver. Junk the existing Copy
The copy you'll need is either NVIDIA Forceware 186.18 for a Geforce type card Or,ATI Catalyst Drivers 9.6 Both are Universal Drivers There are different versions for different Operating systems Visit http://filehippo.com/software/drivers/ to make your choice
