Well heres the thing. The computer is fine for all business purposes, but when I play world of warcraft after aout 3 hours the computer totally shuts down, its like if you yanked the power plug out. This does not happen however if i remove the case side door. I think that is has to do with heat but there are no warning or notices on the computer. If i dont open my case the computer will keep crashing about every half hour. This has been happening for a while now. Any suggestions?
