Device driver was not successfully installed (no driver found) on Windows 7 x64

I have had this problem for quite some time now, but tried to fix it on and off.

I knew I had problems with USB devices. Not even a standard keyboard will install.

Here is what I have found out:

I have a standard keyboard which I have used on this computer before.

Now it ONLY works if I plug it into the port I installed it on originally.

ALL other USB ports fail.

I then started trying moving other devices around.

They all ONLY work in the ports they were installed on originally.

ALL report a "no driver found" message when trying to use another port.

I then decided to check with a webcam that I never installed on this computer.

It fails on ALL ports.

So it's not only one port or one device.

I now want to move a 3TB harddisk from another computer of mine.

I have a USB3.0 dock that I KNOW supports 3TB drives as it already run one, but on another pc.

On this one I get the same error as in the title, no matter what port I try.

I then decided to pull the drive from the USB dock and mount it internally.

It STILL gives the above error as shown here:

It's almost as if Windows have lost ALL drivers for ALL devices??!?

I have tried the following:

commandline as admin > SFC /SCANNOW

That reports that eveything is fine.

I ran CHKDSK on all drives

No errors.

I tried running the following antispyware:

superantispyware

Malwarebytes Anti-Malware

AdwCleaner

CCleaner

All gives a clean bill of health.

I read other people went into the device manager and deleted all the USB devices, so I tried that.

That made my mouse and keyboard die. Forced shutdown. Boot.

Then Windows showed me I needed USB drivers, but I could not get them as mouse and keyboard didn't work.

I had to boot on my Recovery Disc, and do a system restore.

I don't know if it's any help but I have this from an attempt to run a repair:

I am really getting deperate.

Oh, as a sidenote. Reinstalling/resetting Windows is NOT an option!
