Mach 3 DROs show movement, motors do not move until PC restarted

I tried searching for this, but had no luck, as Im not sure what to search.

I switched computers awhile back, system was all working fine, but computer needed upgrading. Now using a Dell Dimension 3000. Everything works fine now, except it seems that if the computer sits long enough without me using it (not sure how long that is, or if its when it sleeps and wakes or what) I start mach 3 to cut something and i go to jog the motors, and the DROs show movement, but the motors do not move. I can see limit switches being switched on the diagnostic page, thats what gets me.

Also, it may be a completely different problem, but everyonce and awhile, when Mach 3 is running (so far, not when cutting) it has locked up the computer. But I cant figure out why?

I have the onboard Parallel port in Epp mode I believe, and then a pci double port card (used without any problems in the old pc) it has a 3.2 ghz processor in Hyperthreading mode, and 2 gigs of ram running 400mhz dual channel.

Any ideas?
