Windows 7: Win 7 slowed to a crawl

My system has slowed to a crawl (and rebooting makes no difference). Every mouse click takes anything between 10 and 60 seconds

to get a response and most programmes state 'not responding'.

When I boot into Safe Mode it's fine, so I'm guessing it's not a hardware problem. I tried rolling back to a system restore point

just before some software and updates were installed (they were updates to Acrobat Reader plus installs of a You Tube downloader

and a Video Format Comverter) but it makes no difference.

I tried looking at the Event Viewer but couldn't make much sense of it.

Presumably, if I can start in Safe Mode and then gradually add whatever else loads I can find the culprit - but how do I go about

doing that?

Don't know if it's relevant but Windows Explorer keeps falling over (which it seems to do a lot) and Kaspersky Anti_Virus was



reporting a database corruption, but it now seems to have recovered form that since I rolled back to the restore point - though

unfortunately it wont run in safe mode.

Run a anti virus scan.

Download this and run it, too


Malwarebytes.org

Then try a repair install, I will get you the instructions from excellent tutorial collection.

Repair Install

If you can get to this point, this will be a big help. But try the above first
