Wierd GPU issues after "Upgrade"

[ddvindas]

I got an MSI NF725GM-P43 for free with an included Phenom II x4 945, so i swaped my old Biostar G41D3C wich had an Intel Pentium E5700, i just suaped the 8gb of ddr3 that i alredy had in, so after playing arround with the bios (i OCd the CPU to 3.5ghz, i had a beefy cooler on it so it barely reaches 50C) i started noticing some GPU issues, sometimes randomly the screen just went completely black, the GPU is a GTX 470, and used to work perfectly on the old motherboard, so the only way to get it back was to restart the computer, but it was working ok, it sometimes crashed while running MSI afterburner, didnt OCd the GPU tho.
i did a lot of troubleshooting alredy, and even updated the bios to the latest version but the issue persist, im hoping it has someting to do with bus frequencies (i alredy put the bios to defaults and the problem persists) or with the integrated VGA configuration or someting, im using windows 10 home 64 bits.
i dont want to go back to the old motherboard since with this one i can play overwatch perfectly but with the old one it didnt even run (really strong cpu bottleneck) please someone help me find the root of the issue and posibly fix it!!
Thanks in advance!!!

you will likely need to reinstall drivers for the GPU. I have also heard that windows sometimes doesn't play nicely with a changed motherboard

i did tried this, but it seems there is like an issue between the integrated graphics of the motherboard and the GPU, and i cant seem to find a way to disable the integrated graphics on the BIOS but since i updated it i cant seem to be able to find that option anymore, PLEASE HELP!!

i also noticed that when i did get into windows, giving a bump to the desk inmediately disables the video, is it posible the PCI-E slot is damaged?
