Windows 10: Headset Sound Distortion, Keyboard Malfunctions, Other Malfunctions

OS: Windows 10 64-bit

MB: MSI Z77 Mpower

Keyboard: Dell (Generic)

Headset: Plantronics Gamecom 780

Symptoms:

Sound from the headset will occasionally distort with a buzzing timbre regardless of currently running application.

Headset will stop producing sound and recording on microphone regardless of currently running application. Very rarely, this will be accompanied by a complete loss of keyboard functionality and can only be fixed with a PC restart.

Attempted Solutions:

Reinstalled motherboard audio drivers.

Reinstalled headset drivers.

USB Malfunction

I have Windows 7 64 bit on my ASUS laptop and am having problems with the USB for my ddr mat.

USB headset, mouse, keyboard all work. The DDR mat driver installs and works on other computers and laptops but on my laptop it gives me a driver not found, USB has malfunctioned/damaged. I have tried it in all of the different USB ports on the laptop, nothing works.

Any ideas?

 

Specific Keyboard Keys Malfunctioning

My keyboard keys have recently been malfunctioning. Sometimes, the keys do not register at all, and sometimes, it as to be pressed and held with force to register. Only a few select keys are effected, namely the: right arrow key, \, e, g, h, and 8 and 9 on the numerical keypad.

The keyboard was the factory keyboard included with my Asus X751LD laptop.

This started after I used a Java application. It is very unlikely to be a hardware issue, as the laptop was never moved or subjected to drops. Another possible factor is I have used Autosofted Keyboard Presser.

The keys function, although with lag, after startup, but stop working within a few seconds.

I have tried the following to no avail:

• Restarting
  
• Restarting in Safe Mode
  
• Updating keyboard drivers in Device Manager
  
• Updating Java

Does anyone know how to fix this?

(Was a pain typing this, makes me understand just how much I use the e key)

Edit:

I tested the keyboard with a Linux live CD. First time I booted, the keys will not registrar in a notepad app unless I repetitively press them around 20 times. I rebooted into Linux again, this time the keyboard worked OK, but missed keystrokes occasionally. In both situations it was the same keys as described above that were malfunctioning.

After rebooting into Windows, the keyboard functioned like the 2nd situation above (occasional missed strokes) for around 5min. Then no amount of pressing on the malfunctioning keys could make it register.
