This just started today. I launch Illustrator CS4 amd all of a sudden my CPU usage spikes, it only shows that it's using 146mb of 4gigs of RAM and even after I close the app after several tries, the CPU usage is still spiking. I have to do a hard restart to get my machine back. I have tried resetting my AI prefs as well with no luck. My specs are as follows:
Windows 7 Ultimate 64bit
BFG GeForce 9800 GTX
XFX 8200 GeForce mobo
4gigs of DDR2 RAM
--DRIVES--
Primary-250gig WD
Secondary-150gig WD
HP CD/DVD
my system is self built.
