100% CPU Usage! Why?

**gun_men4hire** · April 27th, 2001, 07:27 AM

Whenever i open my Adobe Illustrataor on my NT4 workstation PC i get 99/100% cpu usage??? why does it do this? I have had the WINS service do this aswell on another PC what is the cause and more importantly the resolution? This does not happen on my Win 98 PC. I will go insane if this carrys on! please help!

Maybe its programmed a little differently...when some programs wait for user input they max out for processing time... I really notice this on FTP programs. When they wait for server response their Time maxes out.

You always could turn down the priority of the app that does that.

OK try'd that... no change...

I tryd illustrator ver 7.01 and that was ok but not in ver 9.02, which is the one i need to use. The problem with WINS is still there but is intermittant. + illustrator is not on that system so im still blaming NT for this one... ARRRGH!

Maybe some one else will no a better solution. I can't think of one Right Now. Good luck with it.

If the machine is thrashing to the swap file a lot / you have low RAM then it will use a lot of processor time to move chunks of data from swapfile to ram and back.

Do a bit of monitoring of the swapfile usage, available RAM and hard page faults.

Does it max out when you first start Illustrator or only when you get started opening images and such.

If the latter than cordon's idea is probably your solution.

Are you networked?? What SP are you running? What is your network configuration? What NOS is on your server.? The reason I ask is that Win9X is a little more forgiving than the NT flavor OS's out there, under NT a network issue could cause these problems.
