Blue Iris PC died and I’m not sure why

Hi, I built a Blue Iris PC back in April. It had been working ok, occasionally the computer would shut off and I was not sure why. I had gone through and changed all of the windows setting to prevent it from shutting off. However I was always able to just restart it and my cameras would start working again. I did have BI setup to run as a service.
The last time the computer shut off I have not been able to restart it. When I try to power it on, the computer beeps twice. I get an HP Sure...
