I plugged in a GTX 1050 with a riser(powered by MOLEX) i connected my monitor to it and when i try to mine the screen turns green and my PC restarts. The riser is plugged in the PCI x1 slot, I also tried it on the PCI x16 slot(i made sure that i plugged it correctly). I am pretty new at this and any help would be appreciated.
Green screen or blue screen? Anyway, try to run your GPU without riser ( I don't see any reason to use a riser if you have only one GPU installed)
