Hello, I would be very grateful for some help regarding my 2.0GHz iMac G5 with 1gb of RAM. The problem I am having is with User CPU % loads that continually hang whatever program I am using. This can occur when simply browsing in Firefox and it is the only program open, Illustrator CS3, and very often the print manager app will spike and hang when printing. I observe this happening with the activity monitor, a program's load will climb and at around 85-90% User CPU, the program will not respond and have to be force quit. This doesn't occur every time but does more often than not.
The activity monitor seems to suggest the User CPU % is strangling the System CPU % for resources and forcing the program to hang. My first impression was that it is a RAM issue, but when it occurs whilst simply net browsing, it feels odd. Does this point to a hardware fault, something allowing the User CPU % to throttle out of control? I did a fresh install of Tiger recently when I replaced the original failing hard drive with an IBM (Hitachi) Deskstar 7K1000.C SATAII 500GB 16MB. Would it be worth trying another fresh install as I have exhausted all the other avenues, reset PRAM, repaired permissions, etc?
Thanks in advance for any help you can give. My partner uses this iMac to run her small greetings card design business and it is driving her up the wall!
