Question about Computers & Internet
When I leave my PC unattended for a while, these little square color blotches appear all over the screen. If they're on a window, refreshing the window clears them. Even a local refresh, like if there's a mouseover script on a page element in my browser, then mousing over the element will clear the effect from that element, but leave it everywhere else on the window. The worst, though, is the wallpaper. Once the blotches are on the wallpaper, nothing refreshes them, until I reset the wallpaper. What's causing this? A graphics card going south? A virus? Solar flare activity?
The most common reason for this is your video card overheating. You did not post the make & model of your computer, but if you have a separate video card installed check it for overheating. Pull the side panel off the computer to inspect. If your card has a cooling fan make sure it is still working (it may have failed) and not clogged with dust. If you have integrated video (the video "card" is part of the motherboard, not separate) check for dust & clogging in the vents. This is especially important if you have overclocked the GPU (video card processor) or the CPU, many gamers do this.
If you are still having problems, I hang out at www.suggest-a-fix.com, a free help forum. Post in there and we can go deeper. This forum is just not set up for in-depth communication.

Solution found by altering the screen resolution, this brought the mouse under normal scrolling control
