Today I randomly decided to take a look at what my Desktop's RAM looked like by carefully removing the single 8gb stick of RAM. After I had observed it, I carefully placed the RAM back into its slot (I can assure that it was re-inserted correctly). Then I started my computer, nothing was displayed on the monitor... and all I heard was my loud cpu fan not slowing down as it normally does during boot. Does anyone have any idea why this happened and what I can do to fix it? Any help is greatly appreciated.
