INSPIRON 660s Solid Amber light and 5 Beeps

Hi,

I have lost the power supply for this PC so I tried running the PC with an ATX power supply, and I get this amber light with 5 beeps! I bought this in 2013 and want to run it as my secondary PC now, any help?

I temporarily gave it away to someone for a few years and they have returned it to me. The CPU fan and everything runs just fine, I also unmounted the RAM stick and heard the two beeps, but I am yet to try replacing the CMOS battery.

@redxps630​ Hi, thank you for your reply.

I just tried the CMOS reset with the new battery and it's still the same, glowing amber light and 5 beeps.

Do you suspect motherboard failure or something else?

Thanks I did go through that page and it says the Solid amber could mean

Solid Amber The system board cannot start initialization. An issue with the system board, memory, processor, or the power supply.

This is so confusing, I tried two batteries and they are both new but still no luck
