Pressing multiple keys at once

[Dart3055]

Hey there, I'm an avid gamer for the most part, and i'm having a problem involving hotkeys, See there are times when i have to press 2-4 keys at once in game, sometimes holding them down, which causes my computer to have a spazz attack and beep annoyingly while it ignores the commands of most of the keys. Does anyone know of a way to fix or better this problem?

Start -> Control Panel -> Accessibility Options -> Turn off StickyKeys.
