Alright, so in all my years of hoarding/fixing computers of all types I have NEVER in my life seen anything even close to this.
I’m aware of the notorious PSU problem on MDDs, I have one that doesn’t work because of that. I don’t think that the PSU is the problem this time, but that’s why I’m posting here. I can’t find anything like this on google either.
Here’s what happened. After I got this MDD all set up, HDDs and SATA card installed, I moved it over to my main desk that has a KVM switch. The MDD is replacing my Mystic G4 on the KVM. It’s a basic switch with USB, DVI, ect. The screen hooked up to that is a 23” ADC display. Anyways, I had just played with the MDD for like half an hour at a different desk with its own monitor and no switch. I moved it to the other desk with the KVM, turn it on and then it just shuts off! I turn it on about 10 more times, each time shutting off within about 5-10 seconds. I start troubleshooting, turning it on with everything unplugged but the power. I notice it stayed on, so I plugged everything back in. I saw my desktop for about half a second and it shut off again! Next time I turned it on with only the Ethernet and power cable, doing this allowed me to use it via screen sharing (it was already enabled due to the drive being in my Mystic prior to this). I was able to use the MDD as long as I wanted via screen sharing, so I plugged in the DVI cable. Not 3 seconds later it shut off!
To make it make even less sense, the other monitor that it was hooked up to at the other desk is also DVI.
TL;DR: MDD powers off when DVI cable is connected, and only shuts off when the DVI is connected.
I’m stumped. Could the card be drawing too much power at 1920x1200? (A sign the PSU is toast?) or is the GPU just bad and won’t display at that res?
