A quick explain might be called for, if you already know all this someone else might find it useful.

Windows time slices the processor, that's how it can run several programs at the same time. A Windows programme is actually a whole mess of unconnected programmes all working to a common purpose.

For example: You ask Windows to put a button on the screen, a resource. You the ask Windows to allocate the button to you, and come to you should someone press it. Your button might require part of the screen to redraw but your button can only invalidate that part of the screen. Nothing happens until Windows asks you redrawing program to refresh that part of the screen.

Without time slicing the machine nothing works.

MACH has to assume that other programs do not create appreciable delays. If they do you get glitches. That is why you you want to crock everything possible apart from MACH.

AVG 9 has a bad habit of creeping across your disk checking files. I know this because I had a corrupt sector on my disk, if I tried to read it Windows crashed. It took about half an hour for AVG to find it running it's background scan and then POW, dead machine.

Go through your Start up and crock anything you can get away with.
