I've started having this strange problem. Windows keeps locking up, mainly when I'm using Internet Explorer. For instance as I'm typing this text it freezes, in order to regain control I must move the mouse out of IE and over the taskbar at the bottom of the screen. The screen will flash blue and will then let me carry on using IE. It seems to also happen a lot when scrolling down web pages, either by using the scrollbars or the mouse wheel. The problem has also occurred in other applications where there are scrollbars.
Once this has happened the screen often doesn't redraw itself properly and I have to force the screen to update itself by either scrolling the page I'm on, or switching to another application and back. This problem only started 24 hours ago, it's been two weeks since I've done any Windows updates. I've just done a scan with my virus software, and I have done the same with the Symantec online virus scanner. I don't have any viruses.
Can anybody help? Thanks
