I'm not sure if this is the right section to post under but I'll try anyways. Recentally I took my computer and put it where another computer of mine used to be for convenience, and after doing this every so often the computer crashes. I thought maybe the monitor was just broke and kept turning off on me, so I changed the monitor with a spare one I had and that didn't help. I took my case off and made sure I didn't knock anything loose but didn't find a problem there. What happens is I'll turn on my computer, sometimes it'll turn on like right now, and other times it screams at me. When it does turn on my monitor will randomly turn off like I shut my computer down. The green light meaning its on turns orange which is normal if I were to shut my computer off or if I put it on standby by or something. So when this happens I try and move my mouse thinking ohh it's just in screen saver mode, nothing happens though, I press the sleep button on my keyboard, nothing happens, and I have to end up using the on off switch on the back of my computer to turn it off. The front on off won't work. Just wondering if anyone could help me. I'm lost.

Can you see that the lights are still on the tower? Can you hear the fans spinning? I would also remove the video card (if applicable) and reseat, also check all connections inside the case and the connectors from the case to the monitor

Try replacing the video card.
