Computer Randomly Restarts and screen shuts off.

[Jellyfish789]

Hey, I have been having an issue lately with my new home built computer. It will randomly restart without displaying any message, and sometimes it will stay on but the monitor will enter power save mode, and won't turn back on which forces me to force shut down. I have already tried re-installing video card drivers, and deleting malware. I thought I fixed for a while, but then it did it again today. Any ideas?

I'm leaning towards a power supply problem or the graphics card is having troubles. What are the components in the machine?

Try removing the graphics card and using on-board video.
