Display monitor not detecting signal

[BM21]

For almost a year I’ve been unable to turn on my computer and display an image. Until recently I decided to turn on my computer after months and the computer booted up normally but blanked on startup. I entered safe mode and everything went smoothly but instead of installing any pc recovery methods I went to system recovery and restored to a point in maybe April of 2019. I came back to see red pixels on the screen and had to shut off the computer and since that I’ve been unable to get a signal working again. I’ve tried to speak to a virtual agent, I don’t have any beeps, the lights aren’t blinking and the fan is spinning. I do have a loose latch on the gpu but I searched up that it shouldn’t be an issue.

I also while the monitor was still displaying, did a factory reset of the screen. But I don’t think it was an issue either
