Hello;

Have an Asrock H81 pro motherboard with pciex16, pciex1_1,pciex1_5&pciex1_6 installed with 7950 via usb power riser, except pciex16. When I run sgminer after a few or several always lees than 24 hours I find that my pc is on but the screen is black and it is not hashing because my pool emails me when my rig is not hashing and I can't access my rig through my mobile via remote desktop. Any solutions or reasons why this is happening?

This occurs if the cards are overclocked or not.

PSU: Thermaltake:1275w platinum, Seasonic 1050w gold
 
Remove cards one at a time until the problem goes away. Then try swapping the card into another slot so that you can track down whether or not it's a bad card or a bad slot. If a certain number of cards always fails, no matter what cards or slots, then your rig probably has a power problem.
