CPU and DRAM problem, Motherboard USB and HDMI outlets aren't working

[sinizano]

So I'm a complete newbie to building computers, having no prior experience. I built a computer with a friend who knew how and when I finished, (I finished after friend left) I turned on the tower and the monitor and booted it up to be presented with the diagnostics screen that shows everything is in working order. I leave the monitor and tower on in order to go order an optical drive and operating system (as I didn't have any) I come back around 40 minutes later to see the diagnostics screen having a red fuzz and the monitor is frozen. Clicking the mouse or pressing on the keyboard didn't do anything, so I turned the whole tower off and on. The fans and LED from the motherboard are working but my monitor isn't recieving a signal, my keyboard and mouse are off (I can tell because they are supposed to have a back light) and they are all connected to the motherboard outputs. I don't know if one or more of my parts aren't working and I don't have much computer knowledge to help me out. Can someone please help me here? Thank You!!!

Update - there's a light that signals that there was something wrong with the CPU and DRAM, just don't what exactly or if it correlates with the motherboard problem.

If starting the board without RAMs, still CPU LED on?
