So I left my desktop sitting in my room for over a year without use because I had to move away for school. It has not been used at all during this time period and now when I plug it all up for the first time, it does not boot. I cannot even get to bios. It just powers on and sits with black screen. The motherboard has two diagnostic lights that are supposed light up as green if everything is functioning right but instead I have one blinking red and one off. In the manual, it only talks about the light as on or off and not flashing. And the closest one I match that error code to is ram error. I'm confused how this could happen if I haven't touched it for so long. Any ideas what's up?
