Small "glitches" in system
 

Every 30 seconds my computer glitches. For example, I am typing this right now, and it takes about 3 seconds for the whole word to appear even though i wrote the word in 1 second.Also, I press backspace on my keyboard and about 4 seconds later it finally deletes the word. THIS IS NOT THE KEYBOARD. I HAVE USED OTHER KINDS ALREADY I was thinking of typing this under the "Games Section", because whenever i play "Halo" for PC, it slows down and glitches for a few seconds and is very frustrating. But, since it is happening also out side of games, I decided to post here. Hope you can help!.

I have experienced the same thing, but mine was do to a system slowdown (not restarting my comp for 6 weeks was hard on it apparently, lol).
Try checking the task manager for the amount of cpu currently in use.
Does it slow down other actions, such as opening the start menu or launching applications?

Memory issue?
 

Sounds to me like you've got a load of stuff going on in the background, or maybe some malware...check google for "slow keyboard response" just in case someone has been down this road before... I did, and it is not uncommon... ;)
