Total Power Down in Middle of Starcraft

[berserker]

After swapping in and out a couple of pieces of hardware (Game Theater XP and TV tuner), my PC just hard shutdown in the middle of some old school gaming (just finished SP WC3 also!). Now it will not turn on, not even the fans. The power light in front stays on at about half lumenescence.

Is the problem the power supply or the MB? The case for the PS being bad is that not even the fans come on. However, the case for the MB being blown is that power light.

The new hardware is not in the comp.

It's never done this BTW.

Also how do I get Dune 2 to run, anyone know?

OBTW:
Epox 8rda+
XP SP2
9800 Pro

Edit- twas the PSU, got an Antec.

PSU would be my first guess. What brand and wattage is it?

 

[berserker]

Not sure the brand (I'll check when i get home), but it's 350 watts. I have 1 HDD and 2 optical drives, along with an Barton 2700+. I would think it would be enough.

The brand is far more important than the wattage. A good brand name 300W PSU will almost always be superior to a cheap generic rated 100W+ higher.
