My hubby's secretary's old Dell Dimension 8200 has slowed to an absolute crawl. It wasn't exactly speedy, but now it barely runs.
I discovered she's done no maintenance at all on it, (virus protection current and that's it) managed to clean it up--dumped cache/temp files, ran 2 spyware checkers, installed systemworks, defragged. It's now running, slightly better, but will not run any diskcheck utility, even when scheduled for a reboot.
A norton analysis through diskdoctor shows numerous index problems.
When I try to boot in safe mode, it hangs at agp440.sys
A microsoft support file suggested the safe mode problem, at least, might be due to the chipset drivers needing to be updated, but the dell support site doesn't include chipset drivers, nor any info on which chipset is in this system.
What would you experts do next?
