My computer is having trouble booting up. When I hit the power button, or the button on the motherboard, the computer starts for a few seconds, but then it turns off. Then, without any additional input, it tries to start again. This cycle repeats. No data shows up on my screen.

Prior to this I was having many computer crashes, especially when playing games (not any in particular were affected). The sound associated with such crashes was especially jarring and loud, but not a loop of anything that had been playing. I unplugged my GPU and the computer still won't start. I have tried starting my computer without anything plugged in but the essentials and it still hasn't started. None of my hardware was overclocked.

Hey so I have finally been able to find my manual that told me the 55 on my motherboard LED meant that the RAM is not properly installed. It is not a new computer and the ram is properly installed. If you guys are sure this is a RAM problem I am just going to see which stick is faulty and probably order another one or two.

A related question: Does the RAM have to go in the 1 and 3 slots if you only have two sticks? I want to move it further from my heatsink.

Ok well I ran the Windows Memory test and it said no problems detected...And I can actually use my computer if I wait for a while before starting it again.

Also, the computer only seems to crash when I am playing games. Maybe it isn't my RAM, or maybe it is only faulty in-game?
 

that is a really good certificated PSU, but it seems to me like a PSU issues, generally that kind of issue is related to PSUs not giving enough power to the GPU, or faulty units(PSU).
So check your PSU measuring the 12v rail with a multimeter, or use some software like AIDA64, to see how it works under load when gaming. tolerancy on 12v rail on ATX power supply is 5%, so from 11,4v to 12,6v, if it drops below that you have a bad PSU
