      This could be as Bigyin has said be your graphics card or the drivers for the card. It could also be something simple and as I know to my cost trying to " Fiddle" with it normally ends in you deleting or losing some of your software that was not causing any of the problem in hand. 
   
I think it best if you pop your laptop into the computer shop he will look at it there and then.He has done the odd job for me and did not charge me We bought 2 laptops for the kids for school from him and the after sales is first class.   8-) See below from my earlier post. You could speak with him on the phone.There are two guys in the shop it's the younger that's speaks English.

If you want a cheap reliable computer shop I can recommend one it's in LAldea He is both knowledgeable and honest rare I know but I can only take as I find. He speaks English and his shop is a few doors down from the English shop that closed a few months ago. His number is 977451293. Address Av Catalunya 356 , L`Aldea 43896.

The shop is here....

Or tell us here on the forum your laptop name what windows you are running etc and the make/model of your graphics card and bigyim may be able to point you in the right direction. Have you tried to go back in windows to an earlier time when the laptop was working OK ? using Windows system restore ?
