My computer screen keeps freezing and I have to keep turning the computer on and off

Hello everyone - I am a new member of the forum and hope that someone reading this might be able to help me with a problem I have with my computer.

In recent weeks the computer screen keeps freezing with the cursor being replaced by the hour glass symbol. This usually happens after several hours' computer usage - but sometimes it occurs soon after the computer is turned on.

When this happens, I am unable to log off; the computer on/off button does not work when the screen freezes and I have to turn the computer off at the mains.

In order to be able to log back into my broadband internet connection I have to turn the computer and and off twice and then on again .

Sometimes when the computer screen image freezes a message box appears always saying "End programme" (i.e. "End programme - CiceroUIWndFrame" or "End programme - mixer").

My computer runs on the Windows XP operating system.

I changed from Internet Explorer browser 6 to 7 yesterday but the problem of the computer screen freezing persists.

Any helpful advice on this would be much appreciated.

it sounds like your physical memory and virtual memory are being topped out. open up your task manager and see what programs are running in the background.

also, go to msconfig (start > run > type "msconfig" > select the startup tab) and search through all those programs listed there. uncheck any and all unecessary programs that are not required at startup.

also, upgrading your system RAM would also help
