Have you tried a different power supply yet? Launching an app like FF puts
simultaneous load on the CPU, memory, and hard disk(s). A marginal PSU can
can cause problems like you are seeing under these conditions if it can't
output the current required by the load. This is not uncommon.
Hardware is relatively easy, time wise, to test and eliminate as causes of
failure. Troubleshooting kernels and drivers can be much more time consuming.
If you have another known good PSU swap it in and see if that fixes the
problem. PSUs are the cheapest components in most PCs, and almost everyone
overlooks the importance of a quality PSU when building a machine. They just
take whatever comes with the case they order. Sometimes you get a lemon PSU
this way. Only way to know is to swap it out.
