System Restore is different from a complete reinstallation of Windows, if that's what you were thinking of. . . . System Restore marks major points in your computer's evolution -- like every time a program or driver is installed -- and you can choose to Restore to an earlier system configuration. It's pretty innocuous. It doesn't delete any of your personal files.
On Windows 7 machines, just click on Start and type "System Restore" into the search box. You should see it in the menu above, and you can follow directions from there.
If you have Win XP, it's Control Panel
> System > System Restore.
If you have any restore points available between the time you got the machine and when the problem started, roll it back and see if the problem goes away.
As for rootkit scanners -- some of the malware programs have them built in, so you may have already scanned for rootkits when you ran Malwarebytes. But here's a page recommending the best free rootkit scanners:

and this link should take you to the one they recommend most highly:
