USB goes bye-bye

[sabka]

I have a weird problem, and I'm not sure if it's hardware or software related.

Sometimes, when I do some intensive work (i.e. Noise Filtering for 2 GB Audio files, rendering images,...) for a few hours, suddenly my USB devices loose power. To be more specific, on my Logitech mouse, the light goes out; my USB hub goes out; my Keyboad lights go out - and all these devices become unusuable.

Unplugging and re-plugging of the devives doesn't help - have tried that many times. The only way out is to restart the computer with the reset button, in which I loose all unsaved data.

I'm running Win2K on a Athlon 1.33GHz, 512MB Ram, 80+80+120GB drives.

Anyone have clues to what might cause this? Hardware or software problem?

Thanks for the tips paralazarguer.

I already have a 400W Antec PS. But I might have to look for the Southbridge cooling. How can I identify which part of the board needs cooling?

when I transfer pictures from my Kodak digicam to my computer all my USB stuff stops working too... it doesn't require a re-plug to work.. just as soon as it's finished transferring... VERY messed.

Is the USB hub a powered hub or is it passive?

OK, I checked my temperatures and they are as follows:
CPU: 48°C
System: 34°C

And my Soudthbrige is barely warm - so that rules out overheating.

It's a powered hub. But still, all its lights go out - nothing is connected to the hub right now.
I have the keyboard and hub plugged into the two USB ports at the motherboard (IWILL KA266DDR) and the mouse hooked up to the keyboard (MS Natural Internet keyboard ).

I'm really confuzzled
