HP Pavilion Elite HPE-575a

[BigDazza]

Hello.  I have inherited my late father's Pavilion Elite HPE-575a desktop unit.  I know it is getting on a bit but was basically new when he passed.  It has sat in storage for several years before I tried to turn it on the other day.  I got the '5 beeps of doom' and red power button.  After reseating the DIMMs, it now turns on and appears to run OK with no beeping error codes.  However, I am not getting any video output.  The computer only seems to have DVI and HDMI outputs.  I initially had it connected to a monitor using the DVI but am now wondering whether I had the right type of DVI (checking that tonight when I get home).  With no signal from there, I tried using the HDMI (there are two) to a TV but also no result.  I verified that the HDMI cable was OK by plugging it into my laptop and I get that on the TV ok.  I don't have the manuals for the computer, so can anyone tell me if I'm missing something obvious?  Or what else I can try?

Your  Elite HPE-575a seems not to be listed here at HP's computer lookup site.

Unless I am mistaken you have the  Pegatron 2AB6 motherboard named "cleveland-gl8" 

There is DVI and HDMI out on the motherboard.  If it has a graphics card then the motherboard video is disabled.

There is a bios upgrade for Pegatron 2AB6 here that allows newer NVidia such as GTX-1060 to work but the power supply will need to be upgraded.

You need to be able to get the existing graphics to work first unfortunately.

Thanks.  Unfortunately, nothing simple in the video helped - eg reseating graphics card, checking cables and connections, etc.  Is it possible to run the computer without the graphics card if I remove that and instead use the HDMI port from the motherboard?

yes, take out the graphics card and see if the on-board graphics works!

If it works then you can upgrade to that BIOS that supports the newer UEFI graphics cards.
