So the other day when I got home from work I went to turn on my monitors and noticed my computer was off. I did all the basic trouble shooting, checking connections, making sure outlets work etc. Still broken so I tried changed the cmos battery, cleared the cmos, did the paperclip test and nothing. What I did next was remove the RAM and GPU to see if there was any sounds or codes from trying to boot without either of those and nothing once again. So I figured it was a PSU issue I got a different PSU and tried that changing all the cables to the CPU, GPU and motherboard but still nothing.
This leads me to believe that it is a motherboard issue since there are no error codes or sounds when all of my ram is removed as well as my GPU. Is there any other tests I could do to see if it is actually my mobo before I go buy a new one? If it is a motherboard issue, any recommendations on what to get, only thing it needs is the ability to overclock and fullsize atx.
