Title: New Builld Mining Rig. Display doesn't turn on. Post by: sapstar on February 21, 2014, 07:45:44 PM Hi Guys,
I am building my rig with 5 Sapphire 7950's, AMD Sempron Processor on Gigabyte 970A-DS3P. I installed only 1 GPU to start with and using a 750w power supply. When I start the machine by shorting the power pins, it starts and all fans start fine. But nothing comes up on the display. I connected a system speaker, but it doesn't produce any beeps. Any one else experienced this? Would you help me troubleshoot the issue? I tried swapping RAM to different slots, trying different GPU's, Clearing CMOS etc. But nothing makes a difference. I got an RMA for returning CPU and motherboard, but can you suggest if there is something else I can try before returning. Title: Re: New Builld Mining Rig. Display doesn't turn on.

OK, i take a look which Motherboard you have and see a CPU-Socket where must the CPU have the Pins. Maybe any Pins from the CPU are bent! Be carefully if you put the CPU into the CPU-Socket!

After installing windows, I switched back to the old power supply. It works now. Not sure what the problem was initially.
I have a feeling that the graphics card wasn't sitting in the slot properly. |
