CPU maxing out when Solidworks is running

[ScottHeiden]

My CPU starts running at a minimun of 50% CPU usage whenever I open Solidworks (I've got an AMD dual-core processor; otherwise I think it would probably be at 100% CPU usage) and I can't figure out why.

This problem has been brought up before but there is no solution posted for it: (thread559-63740).

I've reinstalled Solidworks and repaired it (with anti-virus turned off) but it won't go away. I use an identical machine at work that behaved the same way, but it is behaving fine now (I've got no idea what I did to fix it).

Any idea what's going on?

Thanks for your help

What are some other system details--including the make of your hard drive and type of chips?

I just had a problem with mixing a Maxtor drive with a motherboard that uses nForce4 chips--apparently a Maxtor firmware problem. Not the same symptoms, but sometimes the cause of the problem can be very odd.

Reason trumps all. And awe trumps reason.

What other apps and/or processes are running?

Does this happen just when SW is open ... no models or drawings open?

Check your add-ins ... switch off everything you don't need.

Thanks for the replies - they lead me in the right direction to solving the problem.

The CPU usage went to 50% as soon as Solidworks was started, even with no drawing being open.

It turned out the Nvidia video card driver and Solidworks 3.0 just didn't work properly together. I installed the newest driver upgrade available from Nvidia and the problem was solved (at least until Solidworks is upgraded again.

Now I'll know exatly where to start looking when it happens again.

What video card are using and what driver? I just got a new computer also and might have that problem. Haven't got to test it much as I have been busy setting all the stuff up. Thanks

I've got an Nvidia GeForce 7800 GT video card. The driver is the latest available from their website (ForceWare Release 80-Version: 81.98-Release Date: February 7, 2006).
