I'm new to mining (or mining again after I stopped in 2014), and I can't get it working Sad

I'm running on windows with 4 AMD 290x cards.

Miner always crashes almost immediately.

The output I get:

After that it always crashes with the message "EthDcrMiner64.exe has stopped working"

Different startup files I have tried:

Any clue what could be the issue?

Use DDU to uninstall your drivers and install them again. I had the same issue after adding a GPU without cleaning the old drivers.
Also, make sure your PSU has enough juice for all your cards. One of them may be lacking power.
good luck m8
