Blank (white) screen threads

I had the same problem as stated by a few other users and tried to find a solution through Microsoft answers. Unfortunately, none of the replies from the "experts" addressed the actual problem, therefore, their suggestions were way off base. The white screen does not occur during boot-up, nor does it have anything to do with boot-up, therefore all the suggestions about changing the boot process is useless. The white screen appears well after Windows has been running, in fact it seemed to happen randomly while using other programs. I agree that although it was a problem to have the entire screen blocked out by this totally white screen, even unable to view the toolbar, it was easily fixed by using the Task Manager, clicking on the 'BLANK WHITE PAGE" and ending the process, when Windows Vista was updated, that option was completely removed from the Task Manager's list of processes making it impossible to end the dreaded "BLANK WHITE PAGE". After much research and trial and error, I found the solution to the problem. The screen would appear whenever I was using a program that utilized the internet program I used, Mozilla Firefox or Internet Explorer... didn't matter which one. I then realized the problem was with another program I was using for my internet mail... Incredimail had incompatibility problems with Vista. Once I went to Incredimail website, downloaded their update and installed it... PRESTO! Problem resolved. Sure wish someone there would have come up with that solution, as it would have saved me many frustrated hours.
Hope this helps others who might be having the same blank white screen problems.... if you're not using Incredimail, check other programs that might conflict with Vista.
