I have windows xp home edition and i've had it for a while. But, something's happened to it in the past....oh i don't know 6 months that makes it to where i can't type when i first start up my account. to enable myself to type, i have to press the right shift key for about 7 or 8 seconds until i can type. when i first press the shift key it beeps once and at the end of the 8 seconds it beeps again. i've tried everything i could to try and stop this but it mostly results in screwing up my computer even more. i'm not sure if its something wrong with my keyboard or what. please gimme some help on this!
