I damaged the motherboard by connecting gpu to wrong modular psu outlet and ive rebuilt pc which works fine using apu but when i try to run hdmi from gpu it black screens if i plug back into motherboard all is ok i had to reset windows 8.1 which cleared all my 3rd party software so ive downloaded motherboard drivers, latest amd drivers ive also tried cd drive that came with gpu sytem specs are
a10 7850
msi a88xm-e35
8gb 1600mhz
ASUS 2GB GDDR5 Radeon R9 270 DIRECTCU II OC
cit 500wat psu
the system worked fine for over a month before so psu is ok but i have bought a xfx 550 pro to befitted next week an i did replace cpu cooler zalman x5 performa changed to antec kuhler h2o 650 but i dont think the power draw from that couldmake much difference im guessing its either a driver issue or gpu was damaged when mobo an hdd went bad but when connected gpu green light is on and fans run ive also been able to monitor it inhwinfo and all seems ok but when i connect hdmi lead thru card all i get is a black screen i tried changing gpu preferred settings in bios and there is no diable apu option
any help would be great
