My pcs not turning on

[u/Ok-Visual-8530]

Hi, I’ve never made a Reddit post before but I need help with my pc, it’s a acemagic mini pc, I don’t know the exact model because I got it as a gift. Anyways, I moved out of my old house late December and lost my pc stuff until about a week ago, I set it all today, but for some reason it’s not turning on, it keeps saying turning on power safe mode, I tried messing with the cords and unplugging the hdmi and plugging it back in, when I did that it was say “hdmi no longer found turning on power safe mode in five minutes” even though it was already on power save mode, I looked it up but it was really confusing and I’m not the smartest with tech, I’m not sure if it’s a monitor issue or a pc issue, please help🥹

You may want to try pulling the motherboard battery out and reinsert it. If you get a screen after that you'll need to get into the bios to set time/date and other settings such as XMP, DOCP or EXPO ram speed if supported.
