    I have so big problem with my HD 5770 (Sapphire), two weeks ago i bought that card and installed to my old MB and everything works fine. But yesterday i bought new MB (GA-MA790X-UD3P) and CPU (Phenom II X4 965 3.4GHz) and when i everything plug in, the monitor said: "No input signal".
    But with HD 4870X2 and HD 2900 PRO works this MB fine. I have 750W PSU by Thermaltake and 700W Xilence. Im 100% sure, that everything is connected good, but my HD 5770 still not working with this MB (hour ago i tried it to connect to the another MB and it worked fine..).

    Since yesterday I was read so many threads with this problem but nothing helped me.. So I hope that you can help me guys..

    MB: Gigabyte GA-MA790X-UD3P
    CPU: Phenom II X4 965 3,4GHz
    GPU: Sapphire ATi HD 5770 1GB GDDR5
    PSU: Thermaltake 750W, Xilence Gaming Edition 700W

    Motherboard BIOS update maybe? Worth looking into, if you haven't already of course :)

    P.S. Welcome to Guru3D

    I tried newest BIOS version (F6) for my MB , but still not working. And yesterday i sent mail to Gigabyte support, with my problem so they maybe help me, but if someone here will have any idea how to solve this problem, it will be so better and so faster..

    By the way Im long time reader of guru3d, but until now I was rocking to the registration, so thanks for the welcoming :)

    Try resetting the BIOS, clear the CMOS and try again
