GPU preventing MOBO from posting

kmath95 · September 25, 2016

Hi all, this is my first time building and my specs are here: http://pcpartpicker.com/list/z6Jh3F

I seem to only be able to get the motherboard (MSI H81M P33) to post to the monitor when my video card (Gigabyte GTX950) is not installed. I can get the MOBO to post perfectly when the GPU is disconnected from the PSU and MOBO. I figured these two parts were compatible based on pc part picker's compatibility filter but it seems there is an issue. Any ideas on how I can get this all to work?

just to make sure, you *did* plug your monitor into the GPU, and you *did* plug in the gpu's 8-pin power connector right?

if that's not it, chances are it's just a DOA (dead on arrival) GPU, and you just need to send it back to get a replacement.

I tested this with the monitor connected both to on-board graphics output and to GPU, both would not post when GPU was connected. Yes, the GPU 8-pin was connected as well. Fans were spinning and lights were on the GPU upon booting. What could possibly be causing the MOBO not to be posting even when output is through the MOBO's DVI output simply because my GPU is also connected?
