Hi - I was going to reply to my original thread but it's been a while and it appears to be locked. Anyway it was this one:- https://h30434.www3.hp.com/t5/Desktop-Hardware-and-Upgrade-Questions/No-display-after-BIOS-update/m-...

Well I'm glad to report that I've fixed the issue. To cut a long story short I had to do the following:

1) move the jumper to the bb_rec spot.

2) boot PC, it did 8 beeps, 2 long and then 2 short - BIOS was corrupt.

3) created a hp_tools usb stick with the previous known working bios on it - think it was 0.27a

4) power on pc with usb attached.

 

now one other gotcha was i had my monitor connected via vga (on pc) to dvi on monitor and it still didn't work.

so i just happened to have a dvi to dvi cable so connected that and voila it worked, my display was back.

 

the BIOS was corrupt for sure after the hp support assistant suggested to update it - think it was version 0.54 or something.

 

anyway it's sorted.
