PC has been running fine for over a year but suddenly having issues on reboot/boot.

Hey everyone. As the title says - I have been using my current rig for about a year with absolutely no issues. Last week, I went to reboot my system and found that it would not come back online. Fans would run, the minimal RGB I have would run on but there would be no display on the screen. My mobo would present a solid green light on the debug LEDs. If I hold the power button down and to a hard reset and then boot back up it works ok. I have also now started having issues where coming back from having my PC off overnight it will not boot, and I get a red and green light on the mobo. A hard reset has also solved this issue so far and the PC will turn on and run ok.

I’m wondering if my ram suddenly died? Any help would be greatly appreciated!
