Hi, I was trying to get a little help with a work computer. I have a Dell mini tower that has dual screens. It has a new GPU card installed within the last month and a new power supply within the last 2 months. Today one of the screens went black, then the other did soon after. The computer is still "on" but nothing shows through. I have restarted, pulled the case and double checked the connections. I swapped an old GPU into the motherboard to see if it was that. I have also done the same with a spare power supply we have. I am still having the same issue with no output going to the monitors. I run Windows 7 pro. I was thinking possibly the mobo may have gone but I am really lost on this. I am somewhat handy with swapping new parts and building my own machines but this work computer I don't know what to do other than verifying it doesn't appear to be the vid card or the pwr supply. I have plugged one monitor into the original on board video out and that does not register anything either.

You did most of the troubleshooting any one of us here would have done.

For sanity check, test with different monitor. I have seen multiple monitors just die on a computer at the same time.
