I have a Dell XPS 8100.

My keyboard randomly fails, meaning that if i am typing into skype or the address bar, it will recognize an "enter key" after each character when i do not, in fact, press the enter key after each character. It results in my messages looking something like this:

h

i

h

o

w

a

r

e

u

?

I also have issues with my mouse at the times when this is going on. If I click something during these times my computer seems to recognize a succession of clicks as opposed to just the single click. 

The only way to stop this from happening is to turn off my pc and restart it. 

* On an interesting note, when this problem is occurring, it does not affect the way the peripherals behave inside of World of Warcraft. While things are going berserk outside of the game, in the game the single clicks are recognized fine and I don't get the phantom "enter key" after my characters. 

Please help, the problem used to happen about once a day, but its happening 3-4 times a day now. Thanks!!!!!!!!!!
