I was so happy for getting my first GTX 570 "Charged" version from TGT tuning..,But after instal it on my MSI 770-C45 the system wont boot. Gives me 1 long and two short beep what means "Graphic card issue".Fan spins on CPU and GPU but no video signal at all. PSU is LC power LC600H with 600w and 18A on 12V rail. The graphic card uses two 6pins conectors which my psu have but is there enough power to even start that GTX 570. Please help.,,I'm stuck here.
The rest of the conf: AMD Phenom II X4 840, 10Gb DDR3, WD 1Tb HDD.
I just try some GT610 on same PCIe and it's working.
