Motors work right when windows starts up and then stop after a minute or two

[dlbjcksn]

I recently bought mach 3 and a Fireball cnc maching with motors from Probotix.  I am having trouble getting the motors to run. 

If I start up windows and fire up mach 3 right away and jog the motors they run perfectly and nice and smooth.  Then after a little while they start making alot of noise and move in jerky steps.  I tried going through the windows xp setup on the machsupport website and it still acts weird.

I am running it on a desktop computer with a 1.8ghz AMD Athlon XP 2200 processor and 1GB of RAM.

What does the driver test look like when you run it? What kernel do you have set?
