Hi All, I have an Alienware x51 (i5 processor, Nvidea 660GPU). Yesterday the computer randomly shut down whilst playing Fallout 4. It restarted itself after a few seconds, and had a continous beep coming from inside. Although it started up, it would not boot. I shut it down, and after repeating this process of turning on and not booting i left it for a bit. When I came back, I laid it on its side, and it ran fine. Today I am having the same issue, but now it is freezing when I try and run games, then I have to shut it down. When I turn it on, it somtimes boots up fine other times it does the no boot and beep thing. I read that two beeps mean RAM is not installed, so I opened it up and took it out, and put it back in. No change. Can anyone help with this? Thanks in advance.
