Error Beeps (8) - CPU Fan spinning at high

HP Recommended
Microsoft Windows 10 (64-bit)


Hp Z210 cmt workstation 
Microsoft Windows 10 (64-Bit)

, Intel i5, 8Gb (2 sticks), Windows 10 


  • Computer gives 8 beeps with 8 power button led blinks
  • internal fans are running (two case fans, 1 PSU fan)
  • removed memory - same thing
  • beeps stop for 1 minute


  • after 1 minute, fans go into high speed mode
  • 8 beeps, long pause, 8 beeps, continuosly


  • HP error code docs show two possibilities CMOS/ROM corruption; I can't get into BIOS to reset/reload
  • HP error code for MSI mobo states could be video memory
    • I added video card but still same thing (guess I need to get into BIOS to chage to discrete video card); can't go there

      Video Card added ( gt 9500 - (gtx 460 se with code 43 problem )   .)

      hope you answer me .
