HP Support Assistant said I needed to update the BIOS. File name sp87681.exe. I ran it, came up to diagnostics screen. Wouldn't boot off a rescue CD or USB. I put it in Legacy mode to get them to boot, now the computer beeps 3 times, pauses, beeps 3 times, endlessly.
I can't get anything to show on the screen.
Not pleased with HP's support or website, not pleased at all.
