Hello

 

I have this Z620 workstation.. Had a problem with its riser and after some in vain effort I gave up using the riser..lately been experiencing some problem with the display.. It would turn off all of a sudden then comes back on.. Thought might be a faulty cable so honestly, I gave no attention to it.. After sometime if I'd restart the computer l, there is no display unless I shut it down then power it back on.. Now sometimes there is diaplay and sometimes the computer would just beep indicating graphics card issue.. Replaced the card.. PC boots.. Displays normally even after restart but just after some short time there is again the blank screen and I have to restart the pc.. Viola.. Device beeps 6 times again.. I'd try powering on and off and after few attempts it'd run normally for another hour or so then again..blank screen.. Yesterday been a development.. Pc would power up.. Boot to windows.. Few minutes after I'd blink like every second nonstop.. I restart and pc boots up normally then again with the blinking..

 

Tried another monitor.. Another cable.. Another port.. Another PSU.. Bios update.. Bios flash via bios flash ROM option in the bios.. Removing CMOS battery.. Checked if any of the hdds is faulty.. Still nothing😕😕😕

 

Any suggestions? ..
