Seems to be lots wrong with this PC but mostly I can't get rid of all the garbage in startup. Type msconfig and the box flashes for a second then disappears. Tried accessing the msconfig.exe file - but the same. Can't run disk cleanup - nothing happens. Won't run scan disk, nor disk defrag. Starts and stops so many times it gives up. Gets down to 33% system resources without having done much. Tried to update norton antivirus - went thru its paces at the site, paid, and now don't see a button for the download. Also when online (AOL dialup) dozens of persistent popups appear. I would download an adware product but nothing is working right and all is much too slow. Anyone?? Ideas please. I'm desperate.
