3 long beeps and 3 short beeps error on pc

Omen Obelisk
Microsoft Windows 10 (64-bit)

I've recently encountered some issues with my 9 month old Omen Obelisk pc. At first, I would turn the power on to be greeted with a "Please shut off power and plug in all PCei power cables" error message. I messed with the computer power cord which worked for a while, until recently the PC would just boot up a black screen with three long beeps and three short beeps, repeating after the last short beep. Any idea on what the issue could be?
