HP PC 4 beeps + red light not turning on

HP Recommended
HP Compaq 6300
Microsoft Windows 10 (32-bit)

I tried reseating the ram, removing the dust and removing everything but it still made the beeping sound and showed the red light. CMOS battery is working, no issues. Removing or reseating the ram didn't change anything.
