Found this on another place on the web, since none og the above did help, i had a spoolsv.exe thatwent from 0 to 99 % CPU usage all the time.. this worked fine on my pc, i suspect a foulty driver from HP deskjet to couse the problem, but be safe, Backup registry first...
This is what i found;
When you open the Printers window on your Windows 2000 Professional Start menu, or when you try to print, you receive the subject error message or one of the following:
Printer operation cannot continue due to lack of resources.
Subsystem unavailable.
These errors are indicative of a damaged printer driver.
To fix the problem:
1. Right-click each printer in the Printers window and press Delete. Press Yes when prompted.
2. Right-click Printers and press Open.
3. In the File menu, press Server Properties.
4. Select the Drivers tab and Remove all the drivers, pressing Yes when prompted.
