Thanks for the suggestion. I will try a PS from another computer.
Even though the system runs for 5 secs, do you think it could be
the Seasonic? If the PS had gone bad, wouldn't the computer fail
to even start?

BTW, top posting is not preferred in these newsgroups, so readers can

easily follow the thread.

Will keep that in mind next time. Thanks.

Best regards,
