I switched out my RAM it worked one time, I turned my PC on, it worked once, then I turned it off to connect all my cables to my PC. After that not only was the DRAM light on, the VGA light was flickering. So I tried some things and now it's the same as last time, only the DRAM lights up. I think it could be a problem with the motherboard, but any ideas to why this is happening would be great.
