Hey, I've spent all day putting together a new PC and tried everything I could but can't seem to understand if the mobo is the problem. The thing is I bought the mobo "new from factory" and it came with bent pins. Besides that I tried putting everything together but the mobo just lights up for a second and dies.
I know the PSU works because I'm using it with my old rig and I know it's more than enough for my PC. I tried reseating the CPU and RAM but to no avail.
I took the mobo out of the case and connected only the 24 pin ATX and 8 pin power connector but it didn't work either.

These are my specs:

Thanks in advance.

It was new, unopened.
