The person that brought this to me claims it has been working great until recently. The symptoms I'm seeing seems to correlate with heat. You can be enjoying some music and suddenly it skips like a dinged up CD and the mouse cursor and EVERYTHING just stops in frame like a Polaroid. This only seems to happen when the computer "warms up" after a while. You see, once it freezes, if you restart it it freezes faster, as though it is over-heating. So, all I can tell you is that CPU activity just puts this thing in a coma. I've unplugged ALL internal devices except ONE main hard drive to rule out wattage issues, but wouldn't a shortage of watts just make the computer click OFF? Thanks all you that are not so noobish as me.
