Communications Manager error in Vista x64

I'm new to this forum, and first off i just want to say hi to everyone and a thank you in advance for any help.

I have vista x64 home premium on my pc, at least once a day the computer locks up and i have to restart the computer. I checked the error list and every time the computer locks up it says, "Communications Manager error or failed to start". I was wondering if anyone knew what this means. Other than that vista works just fine. Is it a faulty driver or something else.

If this helps my computer is,
Athalon 64 4000+
1GB PC3200 DDR
Biostar GForce 6100-M9 939 motherboard
PNY GForce 7300GS 256mb x16
Sound Blaster Audigy SE 7.1
Maxtor 320GB SATA 3.0
Rosewell 480w P/S

The lockups happen randomly, i could start the computer and it will run for 5 hours or 5 minutes, its really annoying. I had windows xp pro on it before and it worked perfectly with no problems, so i doubt their is anything wrong with the hardware. Again thanks for any help

 

This is all i could find, hope it helps. ed
