I changed to new mobo Asrock 970 Pro3 R2.0 but after change, system started once and then crashed and wont start again anymore. In Ati Radeon HD 4830 GPU there is now red led constantly on, it is located on right bottom corner but i don't know which one it is D1601 - Over temp protection enabled or D1602 - EXT 12V fault.  So which one it is and what I can do to further troubleshoot?

I have triple checked cables, changed GPU to other PCIE slot, re-installed memory, but not working. When I tried GPU in other other and in old system it worked nicely. New HW configuration is AMD FX-6300, 8GB DDR3, Antec 500W PSU, 4 SATA HDD's
