I've been having problems with my computer where, with no warning, graphics, icons and text will start to vanish from the taskbar and desktop. What typically happens is that, after an long length of time (usually 7+ hours), I notice that the application name of running tasks on the taskbar vanish, icons and the clock will vanish from the notification area and the word "start" disappears from the Start button. The desktop and Start menu have the same problems with disappearing icons and/or names. If an icon is clicked on or highlighted it returns, but soon vanishes again. Despite all this, Firefox (usually what I'm using at the time) still displays all images and text perfectly. Restarting the PC solves the problem instantly.
What is concerning me is that while this used to be a rare problem and would only happen if the computer was running for a very long time, it has gradually been happening more frequently and seems to be starting sooner. Scans for spyware and viruses show nothing - can anybody suggest what may be happening?
