Wierd skipping and lockups

[Guato]

I've had this computer up and running for about a week, I've been getting the same activity. In Quake3 no matter what resolution I'm in I'll be playing (singleplayer) and get milisecond freezes, totaly random. I stop moving, its ok, I move again, its like having tremdendous packet loss, only I'm not online.. I also lock up ALOT, and not just in games. Temps seem within tolerable limits..
any ideas? I can't get anyfurther in Q3 because I can't make it through the level without hitting the power button.

SPECS:
Abit BP6
2x366 @ 466 (have changed with no affect)
G400/32DH
SBLive! Value
Maxtor27.2/66

All the latest BIOS/Drivers
(was thinking of trying to go down to 5.30, think that would help?)

I'm not sure about the lock ups but I too had some problems with the game running choppy because of sound stutter. You could try to disable sound to find out whether it's the same problem. I was able to fix this by setting s_mixahead to 0.4.

Guato,

try to turn off the background music by adjusting the volume. Set it to 0.

If you have a Logitech mouse, download their latest driver.
