Hello, I am 14 years old and is is my first time building a PC, although I built it with some friends who have built a PC once before. I have been saving up for ages to build, and I finally got the chance to. And building a few weeks ago, everything worked fine, I even got into the windows 10 desktop. However only 4gb out of 8 of my RAM was recognised. In attempt to fix this, we changed the dimm slots around and things, but instead it just kept turning on and off repeatedly, but all the fans were spinning and LEDs lighting up, however no signal to monitor. So we sent back the ram and got a new pair sent out, but, just as last time, it turned on and off but everything else worked. If someone could please help me as I am not sure what the problem is and I really want to get it working! Thank you.
