So I just built my first rig, and had a blast and it was much easier than I thought it would be. I've been inside a comp and know my way around but never built one from scratch. So I try to install the OS today and while it's 'loading windows files' it shuts off. Hm... I think, so I try it again. Same thing. When I turn it on, I get 2 beeps. When there is no OS disc I get a screen that says something like "insert boot media in selected boot device", I have tried to get into BIOS but I never got a CMOS setup screen. In my mind I'm thinking Motherboard at this point. Yet, it shuts off on a timely manner. It stays on for anywhere from 10-20 seconds then shuts off, here I think PSU. Yet if i try to boot it up again right after shutting off, it is only a second or two that it stays on, and here I think CPU. I saw one thing on another site it could be misinstalled Ram, which I removed and put back in only one and doesn't have an effect.
So here is where I am, and looking for your advice and knowledge. Motherboard, CPU, PSU? And how do I check and go about this.
Thank you all in advance.
