Laptop intermittent shutdown
My laptop's always run fairly hot. It's an Acer Aspire 5738PG (I'll post full specs later) that I bought around Christmas. I always noticed it running hot, but not more so recently than any other time.
Anyways, just in the past few weeks it's begun shutting down at random times while I was using it. There's no warning or anything, and no normal shutdown process - it just fades to black nearly instantly, all power lights off. It's always plugged in, and I know for sure that I'm not doing anything to cause it to happen.
Usually, when it happens (me being a WoW nerd =P) I've got WoW and a few Firefox tabs open. I rarely have anything else open at all, and f it is, it's usually iTunes or Minesweeper, or another Windows game =).

I haven't made any hardware upgrades. I've downloaded all Windows updates as they've been released. I run Trend Micro PC-Cillin as my antivirus program.
From what I've read, it seems like it could either be a heat issue or a PSU issue. I've provided as much info as I think is useful, if you guys need any more feel free to ask and I'll figure it out as soon as I can.
