    Was playing ark survival evolved and my pc just shut off I think it may have overheated because I only have one fan. When I turn it on nothing happens but on the gpu (rx 580) a red light flashes once when a blue light usually comes on.

    Anyhelp would be great thanks.

    Check that the GPU is snugly inserted.

    Like Lunarlander said. CHeck that the GPU is firmly seated. (Paraphrased)
    Even better, if you have an on-board vga? THen remove the GPu and see if it'll come to life just plugged in to the on-board. If that works, then reseat the GPU and check. If that doesn't work it's highly likely that the GPU has died.

    When I have a computer that doesn't power up, the first thing I do is try a different power supply.
    I have an old 2K desktop that wouldn't turn on last week. I opened it up and just removed the connection to the motherboard and 1 of the two hard drives. I took a spare power supply (wrong size and too few watts) and attached it to the motherboard and the 1 hard drive. I pressed the one button and it fired right up. That's how I knew it was the power supply and not a bad power cord or bad power switch.

    I'm waiting for better weather to venture out and order a new proper ATX power supply.

    Also I'd remove the current gpu and if you determine there is no problem with the power supply, use the onboard video for the time being.
