Keyboard for some reason doesn't work in rear ports.

My microsoft 600 usb mouse and keyboard suddenly do not work properly anymore. Whenever I plug them into the rear ports they disconnect and freeze(computer remains running). It sometimes requires a reboot for it to work again. This is really weird and frustrating as I can run my other devices out of the back perfectly like my mic and usb drive.

Changes since problems started developing
-Large Amount of Windows Update
-Cleaned computer with compressed air. Allowed it to dry just in case of condensation.
-Installed new secondary hard drive
-Installed new Nvidia graphics card
-Updated Utorrent and installed conduit by accident. Deleted it.
-Removed 4 files with malwarebytes. Most likely false positives with safe torrents I downloaded.

Things I tried
-Different usb ports in the back
-Updating Drivers
-Disabling and enabling keyboard and mouse settings
-Disabling usb sleep thing in power control
-sfc scannow in command prompt came back without errors
-Disabling HID drivers in device manager

Errors

try and do a system restore to before any of these problems occurred. Start, programs, accessories, system tools, system restore; then pick a date and time at which you know the system was working fine with the rear ports. IF that doesnt work; then you might try and see if there are any updated drivers for your usb hub controller(s).

All my usb hubs appear to be up to date. My system restores are all gone for some reason.

I believe it is not the cable connection as I can run benchmarks and other intensive programs. It is exclusively a keyboard and mouse problem. Could it be my new hard drive I installed in my Marvell 6gbps sata slot. The rest of my drives run of the intel controller. The new hard drive also shows up as a removable drive. Also do you recognize any of the errors I posted.

As I am writing this I am watching a movie of a usb drive in the back ports.

I think I found a solution. I put the command lodctr /R into the prompt and it rebuilt the registry counter settings and I have no errors so far. Lets hope this works.
