B. If 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.
2. Cable connection: Check to make sure that all cables are connected and working
properly.
3. Using the minimum configuration for troubleshooting: Remove all unnecessary
components (starting with add-on cards first), and use the minimum configuration (but
with the CPU and a memory module installed) to identify the trouble areas. Refer to the
steps listed in Section A above for proper troubleshooting procedures.
4. Identifying bad components by isolating them: If necessary, remove a component 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 this 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.
