Computer random shutdown, new assembled computer
I just assembled a new computer with a brand new CPU, Motherboard, and new ram with 8 gigabytes of space. At first when my operating system had 32 bit, it took a while and then the computer would randomly turn off by itself, but I didn't notice because i wasn't there. Then I installed 64 bit and it went well for a while, I installed Steam, Skype, and restored a Minecraft server I've been hosting, and installed a game (Tomb Raider). So I finished installing Tomb Raider and booted it up and the computer randomly shutdown out of nowhere. I tried booting it back up and it shut down once it reached the desktop, and continued doing this despite me moving to different power sources around the house with the computer. I believe that I have a bad PCU (It holds 400 watts) and i am thinking of jumping up to 700 watts.
Am I doing the right thing or is there some other reason its shutting down at desktop?
