Hey all,

I recently purchased a MSI R7850 Twin Frozr OC AMD Radeon HD 7850 for use with my MSI A75MA-G55 mobo.

When I hit the power button all the fans spin and I can hear my drive spin up but my bios does not beep and nothing shows up on my monitor (obviously this means it never boots to the OS either). I have a 700w PSU with the proper cabling (tried multiple cables) so I know everything is powered correctly. I also tried with my 500w just for shits n giggles.

Previously I was using a AMD A8-3870K APU w/ a Radeon 6670 for Dual Graphics and that worked fine. Using only the APU's integrated 6550D or only the dedicated 6670 w/ the 6550D disabled also work fine.

I purchased this on amazon and would love to know if I just bought a dead card before going through the hastle of sending it back. I was thinking it might be the fact that the mobo is pci-e 2.0 and the card is 3.0.

For reference, here is exactly what I am using when it dies.

First check the motherboard manufacturer website for the list of compatible video cards.
It will be listed in the motherboard specifications.

Posting this here as may help someone.

My Cousin recently got a R7 360 had the exact same issue with MSI A75MA-G55. We tried everything, Finally decided to update the BIOS to the latest one available from the website. That solved the issue. Yes the latest bios version is 2.0.

If the PCI-e 3.0 graphics card does not work in your MSI A75MA-G55 mobo/any Motherboard, Please check your Bios version.
