the computer uses windows 7. "a driver has returned from a cancellation call holding the global cancel lock". This I near the top of the blue screen when it happens. I thought it could be infected and have spent the last week getting it all cleaned up with Broni in the malware forum. it seems completely random as far as when the error occurs. only today it happened when I was sitting across the room and the computer was doing nothing. also not sure if it's related but when a window is clicked on to type in, after about 3 seconds that box is no longer the "focus". in other words I have to re-click on the box an incredibly high number of times to write anything of substantial length. any help would be greatly appreciated an thanks in advance for our time.
Try reboot the computer and press F8 key to bring up the boot menu, then select the Last Known Good Configuration option to boot the computer, this can load the working hardware profile. If this not work, try the same menu and select safe mode to boot. Hope this helps. Bill Tech Support Manager

Get either the STOP: error message at the top of the error, or in the "Technical Information:" portion of the error.
