System Troubleshooting 10–3
Publication 6181-6.0
The following are checklists of items that you may have overlooked.
If you are having problems during boot-up:
√
Are all connections secure?
√
Are the device drivers installed?
√
Are the jumpers on any add-in boards correctly positioned?
√
Is the hard drive formatted and set up in the BIOS?
√
Is the RAM memory (DIMM) properly installed? You may want to
re-install it to ensure a good connection.
√
Is the EIDE cable from the hard drive properly connected? You may
want to see if the system will boot from a floppy diskette.
√
Is BIOS properly configured (refer to Appendix B)?
If there is a problem after boot-up:
√
If you are running a software package, re-install the software.
√
If the problem is intermittent, you may have a loose connection.
Check all connections including any ISA/PCI cards. Check that the
memory module (DIMM) is fully installed.
√
Does your system have a computer virus? Run anti-virus software.
√
Try clearing CMOS by removing and reinstalling the battery (on
backplane) and running BIOS Setup (refer to Appendix B).
√
Although the 6181 Computer has a regulated and protected power
supply, a transient voltage in the power line or peripheral cable may
cause a flickering display, unexpected reboots, or a locked up
system. If so, exit the application and start over.
√
Is the EIDE cable from the hard drive properly connected? You may
want to see if the system will boot from a floppy drive.
√
Is the system overheating? Look at the diagnostics light on the front
panel display (if present). Verify that the chassis fan is working and
the filter is clean.
