Computer Shuts Off Unexpectedly

I have recently been playing a trucking game when suddenly I lost control over they keyboard and it would not respond. All the lights on it were lit, which were not before. I unplugged it and plugged it back in, it worked fine and then my computer shuts off, such as someone unplugging it. It turns itself back on, only to have nothing happen (nothing starts). The only things working are the case fans, the CPU fan, and one light on the motherboard and the case light. The hard drives are not spinning or anything, and my monitor says no input. I unplugged it and moved it to a different socket and in more light to see what happened. At this point it did the same thing except the fans that were working were running at a very slow speed, almost to the point where I could not hear it, and the same as described above. The fan on the power supply was not spinning either when I noticed this. Nothing was overheating either. The hottest component was the graphics card, and that was at 100F. I left the computer off for about an hour and then turned it back on with luck. I tried it in safe mode with luck. Then when I tried to start it up in regular mode, I get a BSOD with code stop 0x0000001E. I have had the computer do this to me before, and this is the second time where it acted as like it was having it's own brownout. This description was the second time this happened to me. The first time I reseated everything and it worked fine. Also the first time this happened, and when the computer tried to reboot, all that happened was that it was able to power itself for about a second and it would turn off. I can sometimes hear a bizzing sound from it. Now that everything is working, my power supply fan is working, and it only does not work when it is able to power fans and lights but nothing else.

Here are the blue screens I have been getting in order in the past few months:

stop 0x00000135
stop 0x000000D1
stop 0x0000007E
stop 0x0000001E
