HP z230 SFF beeps 5 times and blinks red light

[TadaKitty]

My Fiance's computer was running fine on with google open and it just black screened and shut down and started beeping. Now it beeps whenever I try to boot it up. I don't have any compatible RAM to test with it, but I did try and remove one RAM stick at a time and the same thing occurred, 5 beeps and a blinking red light

DEAD PC:

page 93 states bad DIMM Ram.  so test them all 1 by 1.  ( one must be good, one can hope, and expect)

7 year old PC check the RTC coin cell battery , below 2.9vdc is bad, 3.3v par.

if the coin fails the beep code might lie to you , so we check MR coin first. (voltmeter any)

did you do a zero power reset yet,?

is still dead,   strip PC down to minimum system. and retest it,

I did test the RAM one at a time. Will have to test the battery at the beginning of the month.

Edit: Just tested the RTC coin cell battery by swapping it out and it booted up just fine, so here's to hoping that was the only issue
