I have a client with a Vostro laptop. I5 CPU, 4 GB RAM, Win 7 Pro x64, huge drive with lots of space. This thing is crawling. it's an easy 3 minutes to the desktop from power on.
Run AV scan (Trend Micro, nothing found)
Updated and ran Malwarebytes (nothing found)
Spybot 2 (nothing found)
CCleaner dumped 10GB garbage and not much from the registry.
msconfig, I shut off everything except the AV and her wireless stuff.
I ran autoruns and didn't see anything suspect there.
I took a look at her programs in Control Panel and there wasn't anything I'd call suspect.
This thing still crawls. Her oldest Restore Point is 2 weeks ago and she claims that the slowness has been around quite a bit longer than that. Quickbooks 2014 takes 4+ minutes to open.
What am I missing? Short of flattening it and starting over fresh (I don't believe that is an option) any ideas?
