It may, it may not. What I'm saying is exactly what I wrote...your PSU is a low end piece of crap. It's not capable of putting out the necessary amperage needed by a modern system & you're putting all your hardware at risk by using it.
Other than that, you need to manually configure the BIOS memory settings, especially the RAM voltage.
