USB problems...

I have run all the checks of my Win7 ultimate 32 OS, running from an SSD with i5 CPU, that are available in the Windows Repair Toolbox, but I still experience the same two Problems again every few days.
My Windows Explorer freezes regularly, especially when dealing with a connected external HDD…
Another thing that simply freezes is the mouse. It happens with both wired and wireless. This can be easily fixed, by simply unplugging either the cable or the dongle, and inserting it again immediately.

Both problems are USB connected, both times connected hardware freezes. What am I missing?

Thanks

 

Thanks, but No, it has nothing to do with that HDD. I have an SSD with the OS installed and a second HDD, only 500GB, also inside the computer. There is folder with downloads on there with around 70GB, and Explorer opens that folder immediately, but a long time passes until the list of the contents appears.
But the main worry is the Mouse and the USB freezing, once that is solved I am sure the rest also will work properly again.
As I already wrote I tested everything that can be tested, so my question is: What is responsible for the un-interrupted working of a mouse connected via USB, both, wireless and with wire, have the same problem.... If it is a software problem I could re-install Win7, but I would like to really know that first.

 

Thanks, the registry gets cleaned regularly by ccleaner, that is the only one I trust, that it does not "over-clean".

This is a singularly built computer with an i5, an ASRock Motherboard and an NVidia Graphic card, where might I get old drivers in that case?

WHICH drivers am I looking for?

I used the ASRock recommend settings, and so far no freezing, but I will wait a while before I trust it.

I occasionally use more USB devices, than I have sockets on the computer.
What kind of device should I buy, to be able to connect 4 USB devices? Seems like they need some external power or similar otherwise, they will not work properly?

 

Thanks that what I thought, I was wondering why there are all these cheap ones out there....

But... the problem I started out with has actually gotten worse, after changing the setting in the BIOS for USB drivers:

Windows Explorer now needs up to five seconds to show the content, after opening a folder (which still happens instantly).

While windows is installed on the SSD, the storage folders are on the second harddisc, an HDD (in perfect health). The point is, that opening that folder and listing its contents also worked basically instantly, and only a few months ago started to take a longer time. When I open a 2TB external HDD (connected via USB!) it sometimes fails completely to do that. It runs a green bar in the adressbar from left to right, which shows the progress, and gets slower and slower, and in the end stops. never opening the HDD.....
I found a few hints in the net, about freezing Explorer, but none of them changes anything....

 

So, if I de-activate the indexing it will have to search the whole disk every time I open it....
