HP G800 Scrambled graphics on pre install of os.

[pooley]

As title.

 

For my sanity, can someone comment with something I haven’t tried.

 

I’ve 2x HP G800 elitedesk computers from ictdirect (I have reached out to their support too).

 

When attempting Windows install it boots from usb but immediately shows a scrambled output on the monitor.

 

I have tried.

Windows 10 and 11 flavours, both give same issue.

Updated Bios

Tried different usb drives

changed from display port to hdmi

Tried different monitors 

Tried an automated usb install to see if it would get to windows eventually.

If I had hair I’d be pulling it out.

 

Thanks

Si
