Question Pc only boots to BIOS

[PureGoldFlame]

So I got a cheap prebuilt a few months ago with the intent to upgrade it overtime. I upgraded the psu and gpu and have had no problems until today.

Today I started Apex Legends and the pc crashed, restarted, displayed the message "preparing automatic repair", then restarted again only to display the same message. It did this 3 times before I held the power button.

When I turned it on after that it booted like normal but was running very slow. It may be worth mentioning that I ran MalwareBytes and it found 20 files it deemed worth of quarantining, which I deleted.

I attempted to restart again, only to have it boot to the BIOS and be unable to boot past it. Whenever I save changes and reset it boots back into BIOS. I have tried changing the boot priorities to all the possible options.

If any more information is needed I will answer to the best of my knowledge. I'm expecting to have to buy a new part(s) I just need to know what is likely causing this problem so I can fix it first.

Specs:
Intel core i5-2400
8192 MB (DDR3)
Radeon RX 580
Corsair CX 750M
MOBO is American Megatrends (don't know make/model because I can't tell from the BIOS)

Forgot to mention that it has windows 10.

If any more information is needed

Yes, try and find out the exact make and model of your motherboard.

My Gigabyte Z390 Aorus Pro also says "American Megatrends" and so do most motherboards, impossible to identify it based on that.

After a while of looking around I'm pretty sure it's a B75 LGA 1155. It also says X7-V124-CA if that's helpful.
