Computer extremely slow

I did that this week when the slowdown and freezes started to happen, I selected both choices and I can telll you that it didn't run on the background but after doing this the same problems remain. Now like davehc said above I rolled back all the drivers that I had updated and so far the computer seems fine.

What should have happened is the next time you booted, the boot process would have been interrupted, and the checkdisk would then have run. And it would likely take quite a while to finish - often overnight on large fines. That's for the boot drive. This would not be in the background because Windows would not be running in the foreground - yet.

On secondary drives, you are often prompt to unmount the drive, and if no critical files are opened, it might run in the background.

That is what I was trying to tell you, took 2hours and 30minutes like usual.

Ah! I see. I thought you were expecting it to run in the background and when it did not, you were thinking it did not run. But yeah, 2 1/2 hours (depending on disk size and condition) sounds right. Sorry for any confusion (besides what's in my head! ).
