I built a custom PC a year or so ago and it's been working great. When searching through my PC Info, I noticed instead of the 8GB (which is what I purchased and installed for the build) it was saying I only had 4GB.
After doing some Google Searches, I seen some saying one of the sticks may not have been put all the way in.
Tonight, I opened up the case, and because my CPU fan is so large, I could only touch the ends of my RAM. It was just enough, because I did notice that one of them was not seated all the way. I then pushed it down gently until it clicked and secured it.
Once I closed the case and plugged everything back in, I received no signal for my monitor and no power to my Keyboard or Mouse.
I also have a Blue Snowball microphone and when I power on my computer, it powers on as well.
PLEASE HELP. I've been searching all over and none of the solutions I've come across have helped.
