Monitor help

[DeadMoneyOC]

So about a week ago I was sitting in my chair playing on PP and then all of the sudden my monitor just blacked out. I turned it back on(restarted) and it did it again a few moments later. I have been having this problem all week.

My computer will turn on fine but it will only stay on for an hour at most. It also seems to work better when it is not plugged in(laptop). I also have to keep it very still for it to work best(not black out). It doesnt turn off it just blacks out. Also the bottom right left area below the keyboard is also very sensitive.

I usually always left my laptop plugged in. I think my computer just might be burnt out. It seems to be coming back to life a little though. anyone else have this type of problem?
