Problem Description
My computer stalls when streaming videos, playing online games, or when i use uTorrent. sometimes it
will stall for no reason at all, when im not even doing anything. If there is sound playing when it stalls 
I get this continuos repetitition of whatever the last noise was. Also every so often when i restart the
pc, it will stop when the LCD poster shows "Det DRAM" and i'll have to restart for it to work. I've run 
memtest and it always shows no problems, getting very frustrated.
note: I've set the memory voltage to 1.80V, and also saw that the memory clock mode was on auto,
and i set it to unlinked and set the memory frequency to 1600mhz as this is the factory default, and
have seen a major decrease in stalling, but it still does stall often enough for it to be a nuisance.
