Chapter 3: Troubleshooting
B. The system becomes unstable before or during OS installation
When the system becomes unstable before or during OS installation, check the
following:
1. Source of installation: Make sure that the devices used for installation are
working properly, including boot devices such as CD/DVD disc, CD/DVD-
ROM.
2. Cable connection: Check to make sure that all cables are connected and
working properly.
3. Using minimum configuration for troubleshooting: Remove all unnecessary
components (-starting with add-on cards first), and use minimum configura-
tion (with a CPU and a memory module installed) to identify the problematic
areas.
4. Identifying bad components by isolating them: If necessary, remove a compo-
nent in question from the chassis, and test it in isolation to make sure that it
works properly. Replace a bad component with a good one.
5. Check and change one component at a time instead of changing several
items at the same time. This will help isolate and identify the problem.
6. To find out if a component is good, swap the component with a new one to
see if the system will work properly. If so, then the old component is bad.
You can also install the component in question in another system. If the new
system works, the component is good and the old system has problems.
