m17 R2, beep code

Lately my laptop (Alienware m17 R2) has been booting up with no displaying and playing a beep code. The pattern is three beeps, then two, then one. (video provided below)

At first I thought it was a display issue. I use a Huion Kamvas 22 Pro as a second monitor and have it hooked up to my laptop at all times, and thought disconnecting it when I shut down the laptop would fix the issue, but it didn't.

I'm usually able to use the laptop anyway if I reboot it a few times but it's a very irritating issue and I haven't been able to find a straight answer anywhere. Any ideas?

Addendum: No issues were found after running pre-boot diagnostics
