Hi, Thanks for posting! When did this issue begin to occur? I would like to confirm when did the white screen appear, upon log on windows or launching your browser internet explorer. According to the symptom, I would suggest reinstall your display card driver with the latest version from the vendor's download website. If it appears on start up, certain things you can try are to find out the root cause of the problem are given below. 1. Have a look whether you can reproduce the problem in safe mode Start your computer in safe mode http://windows.microsoft.com/en-US/windows-vista/Start-your-computer-in-safe-mode If behavior doesn’t persist in safe mode, it indicates that a third party program or service is preventing you from performing the action as supposed to. To validate or determine which service/startup item could be causing this, restart the computer and boot to desktop normally. Once done, perform clean boot. 2. Clean Boot prevents software conflicts by preventing the startup items and non Microsoft services from loading. This way you can safely follow the process of elimination to check which application is causing this behavior. Refer: How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7 http://support.microsoft.com/kb/929135 Note: Ensure that you put your computer back to normal startup mode after completing the troubleshooting steps. Steps are available in the article given above.
