Without knowing more specifics on your Alienware, here are the beep codes for your machine: https://www.dell.com/community/Alienware-General-Read-Only/Alienware-Beep-Codes-Table/td-p/5588971
Either laptop or desktop, both codes point to a possible CMOS battery issue (the battery runs the RTC in your machine). If it's the original, you may need to replace it. If you're comfortable doing so, I would remove and reseat the CMOS battery you have first. If trouble persists, I would replace it.
