Hi there
To make it easier for us to figure out where the problem lies I need you to explain what it is you were doing when the problem came up. Does the error come up as soon as you turn on your computer or is it an error dialog that appears while in Windows?
Please make sure you update your software (including all hotfixes/updates for Windows) and your hardware (drivers). To do these you can visit
http://update.microsoft.com in internet explorer and it'll take care of everything for you. A quick search online points to a driver error, so this might very well fix your problem.
