Guys here is my problem.I got the new computer like 5 months ago and everything worked fine but recently the major problem started and that is when i am in a game (dota 2/wow in my case) and when i do alt+tab monitor mouse and keyboard shutdown at the same time...the problem happens in 1 day then skip 10 and start over again until tonight when i couldn't start it every time it came when the windows log on and then it happens.I re-instaled system and everything seems to be fine checked motherboard ram etc i really don't see the problem.So i decided to see if you guys can help because if you do it would be awesome...thanks.

PS. when i start the computer he is acting like it would work with out the problem it has a beep signals on keyboard mouse and monitor!
 
Please re-explain the situation in a clearer fashion. Your explanation leaves me thinking you've reinstalled windows and everything works now. If that was the case you would have no reason to post a thread so your question or post is quite confusing.
