i think that is not a problem with motherboard..i have used RADEON HD 7770 GPU,HD 6670 in it..it runs good...i have uninstalled all the previous drivers and updated the bios,but no result...i lastly used a HD 7770 with a 6 pin connector it worked fine for me and there is no problem with PSU(500 watts) also...
im using WINDOWS 7 ULTIMATE 64-BIT..this palit gtx 650 ti dont have any 6 pin connector also..fans run,windows sounds but no display...
pls help..
