Solved Volume level automatically increases

Hewlett-packard Touchsmart 600-1050 all-...

Specs: Windows 7, i7 / 8GB
I have several symptoms:
1- Randomly volume level automatically increases. I can not reduce the level as it automatically keeps going up. BTW... the Volume control is selected when I open it up. It's like I have a stuck volume key on my wireless keyboard.
2- Can't use Alt Tab to tab between open applications
3- the task bar will not display the DWM view or small view of any app that is running when you roll the mouse over the app in the taskbar.

System is a HP TouchSmart model 610 (so it has a touchscreen, wireless mouse and wireless keyboard.

I've tried different wireless sets of keyboard/mouse and different transceivers but the problem exists. I've even tried usb wired keyboards & mice and the problem will still occur.

To temporarily fix the issue, I put the system to sleep and then immediately wake it back up. I know power is cut to the usb controller. I also know that the touch screen and all input devices are usb devices.

I've already been down the route of looking at drivers (re-installing) which had no impact on the issue.

So far the only thing in common is the USB controller or HW/firmware. I think this may be a firmware issue with the usb controller but I'm not 100% sure.

Does anyone have any other clues that may help me track this down?

✔ Best Answer
If you can't find a solution their is another way. You might not want to spend the money as I did. I have an Exterior Hard drive and Acronis True Image for making a backup. I can make a backup of everthing on my computer. At the very first when I bought my HP computer i create the
3 DVD (have more just in case their needed) that allows me to restore my computer back to like it came from the Factory. (located in All Programs) I can restore my computer back to like it came from the Factory. Install Acronis True Image and if needed I can use the backup I made. This will also works on a blank new hard drive. --------------------------- If after the Factory install and you still have the same problem you described than it's not corrupt files but your computer electronic that's at fault.
I don't really need a computer, It's just entertainment for me.
You can run Error Checking ---------- sfc /scannow -- I can't say it they will help. You can use what Microsoft calls Clean Boot ----- You can -
Start - Control Panel - Backup and Restore - Create a system repair disc --- Use a CD for this.
