What happens when you turn it on, do you see the BIOS post screens?

Or is it totally blank from power on?

Ok so first thing to do is check all the cables if someone has been inside messing with things.

Then swap is the PSU, could be this and it is also the cheapest option. Just because the PC powers on does not mean the PSU is kosha.

Then as you have said you put RAM in wrong motherboard would be next.

PSUs are notoriously fragile, just because it appears to work and fans spin does not mean it is.

I'd say 90% of these similar scenarios are PSUs.

RAM inserted incorrectly could cause some form of power issue to blow it.

For $20 it's a easy thing to try before you start digging deeper and spending more.
