Random Stuck key and double click

Hey everyone, I have an odd problem. Seemingly randomly my keyboard will "hold down a key" when I let go of it or double click my mouse when I single click. I immediately thought it was a hardware issue so I removed the USB hub I had the mouse and keyboard in, same result. I replaced both the mouse and keyboard with another usb keyboard and mouse, same result. I replaced the keyboard with a PS/2 keyboard, same result. I uninstalled the last 10 pieces of software I've installed, same result. I'm completely at a loss as to what's causing this.

Here's my PC:

Mini-ITX motherboard, not sure of model off the top of my head.
Core 2 Quad Q9550 2.8Ghz @ 3Ghz
4GB DDR2 800
1GB Geforce GTX 460 (850/1700/1900)
160GB Intel 320 Series SSD (OS/Important Apps)
250GB WD HDD (Internal) (Games)
1TB WD HDD (External) (Backup)
Windows 7 Ultimate x64

Problem has existed for at least a month, maybe 2 and it's driving me crazy at this point. If anyone has a similar experience and knows what could possibly be causing this I would really appreciate some help. Thanks.

  1. Two questions,

    First, is your version of windows pirated? Seeing windows Ultimate usually raises flags.

    Second, if it is not, then have you tried re-installing windows?

    1. No, purchased from Buy.com when I built the PC.

    2. No, the amount of effort I'd have to go through to get everything back to how it is would be enormous.
  3. under your keybord settings what is the repeat delay and repeat rate settings for the cursor also check the speed of your mouse activity for the double click and the pointer speed maybe you will have to reduce the speed of both
  4. All of those settings are on the default. Using a program called Passmark Keyboard Test the mouse double click is nearly instant (aka inhumanly possible) and the keys getting held is for an indefinite amount of time until I press another key. I can't describe it any way other than it feels like the peripherals are out of sync with the PC and when it reaches a certain threshold and I happen to be pressing a key or clicking the mouse, it inputs it twice (mouse), or doesn't send the release key command (keyboard)
