Peripherals not recognized/powering

I’ve been having this issue with my PC where whenever I turn it on the power light will show it’s on, but when I plug in the monitor, mouse, and keyboard only the mouse will light up (regardless of what order I plug everything in)

A couple of times I got the mouse and the keyboard to both light up, but even when I managed to do that usually the monitor would not recognize it was plugged into the pc. I only managed to get it to recognize everything including the monitor once, and then it showed me an American Megatrends screen, but it froze and when I restarted it the PC went back to only recognizing the mouse.

I was told this might be a psu issue, and I hope to get it checked out soon, but until then I am just trying to figure out if this is the only potential issue. It was working perfectly fine before this- I had it on and was actively using it like normal and it seemed perfectly fine, but I restarted it because a program wouldn’t open and when it came back on the screen started glitching black suddenly so I ended up restarting it again. After that it just gradually got worse until it ended up how it is now.

I’ve tried plugging it in directly to the wall, unplugging everything and plugging everything back in one by one, and trying different outlets, but nothing seems to make a difference.

Hopefully someone can tell me what this might be caused by. Any help is greatly appreciated!

Turn off the rig, unplug from wall and hold in the case power button for several seconds to “flush” any faults and help recognize hardware. This is a long shot but has worked. Remove your ram DIMM modules and then reinstall. If still a problem then try only one ram stick at a time, checking for peripheral power each time. Make sure peripherals are plugged in before booting pc. Sometimes if it doesn’t see a device it won’t load drivers for it. Uncommon but still happens. Good luck.

I just tried all of your suggestions, but unfortunately I had no luck. Thank you for your help, though!
