Device Manager empty. USB ports not detecting

[Lovepeaceguru]

I'm about to explode with frustration!

Problems started when USB ports seemed to spontaneously stop working. Then Device Manager window is empty. Nothing shown at all. Also My Computer takes ages to load and system often seems to hang

Have run every spyware and virus scan possible. Followed instructions on Annoyances forum but still no joy. PnUP is switched on.

750GB in 1x 200GB and 1x 500GB

I have a partial resolution to my problem!

Thanks to everyone who offered help.

First option was check that PuNP was started - OK. Later I discovered that Universal PuNP must NOT be started!

Second option was Aproposfix which I assume is to get rid of some specific spyware/adware/malware.

Third was I tried editing some permissions in the registry but I didn't really understand what I was doing.

Fourth was I ran sfc/scannow - whatever that is!

Also system was hanging on startups and shutdowns, sometimes needing the big switch to get out of it. Now you can click on IE or My Computer or Control Panel and it takes ages for them to load. Usually I find myself with about five instances of each all loading at once.

Frequently web links won't work. The only thing I can do is avoid a left click - use right clicks to save shortcut and then paste it into address bar. I have tpo switch back and forth betwen web browsers using teh Task Manager. OIften the Task Manager itself freezes with the button still "pressed down".

I've also been using my SpeedUpMyPC utility which allows you to give CPU priority to a particular window. A combination of this, Task Manager and a hell of a lot of patience just about keeps me going

Oh, and I updated all my chipset drivers along the way.

MY DEVICE MANAGER WINDOW IS NOW FULLY POPULATED!!!!!

Oh joy! The printer is working too. The solution? It was to do with permissions. I had to spend a lot more time and give a lot more thought to it. (I still don't understand it properly). It's in HKEY Local Machine "Enum"
whatever that means?

So many thanks to the Annoyances.org forum which first gave me the idea for that fix.

BUT!!

Some things are better like loading IE or My Computer or Control Panel. They're still slow though and I can still find myself with loads more browser windows open that I need. On IE though browsing still suffers froim the same problem. Links won't work. I have to copy shortcut and paste into another window.

Java linlks often don't wprk eiuther. I uninstalled and re-installed Java. Maybe there's some slightimprovement but browsing is still a pain.

So now it comes down to a performance problem, mainly in IE.

Shall I uninstall and reinstall IE?

Why has this happened. Could Malware/spyware viruses be reponsible?

Any help gratefully received and because it's only fair, I'll make sure every forum gets a full report when it's all fixed (It will be won't it?)
