Please help with a computer issue....

On Monday my wireless mouse stopped working that I got for Christmas. Greg took it back and got me a new one. That one did not work either. We unplugged it from the mouse port and plugged it into a USB port and it worked fine.

This morning my keyboard stopped working. The keyboard is not wireless. I did a restart and then it worked again.

The same thing happened with my mouse. I did a restart and it worked.

My keyboard stopped working again this afternoon so I did an uninstall and then a reinstall and it is now working again.

This has NEVER happened before and I'm at a total loss as to what is causing it.

I cleared my history, deleted cookies, uninstalled a Walmart photo manager that I installed about a month or two ago, I updated my virus scan (it does this automatically but I did it anyway)......

I'm so worried that something is really wrong......please help!
