Back to Contents Page Software Checks: Dell Precision™ WorkStation 620 Systems User's Guide Overview Program Conflicts Installing and Configuring Software Memory Address Conflicts Error Messages Interrupt Assignment Conflicts Input Errors Overview Because most computers have several application programs installed in addition to the operating system, isolating a software problem can be confusing. Software errors can also appear to be hardware malfunctions at first.
Program Conflicts Some application programs may leave portions of their setup information behind, even though you have exited from them. As a result, other application programs cannot run. Rebooting your system can confirm whether or not these programs are the cause of the problem. Application programs that use specialized subroutines called device drivers can also cause problems with your computer system.
