I tried putting an AGP card in there and I realized it is able to power it up because the fan of the card spins.
That just means the 12V rail is conducting into the slot. It's not a sign of very much.
There are also 5V and 3.3V rails going into the same slot, the fan doesn't confirm those, and we don't know if voltages are close to spec.
The beeping though does mean that the CPU is powering up and running. That's a sign of some life.
Do you have a multimeter? Try to find the other end of that trace and check for continuity across the scratch. It can be hard to get the probes to contact the pads so don't give up too quickly, you might have to push and twist a bit to get the probes into contact.
I don't have this board so I don't know if it would be normal for it to power off after a minor fault like "no RAM".
After it powers off, can you just switch it back on again, or do you have to reset the PSU by unplugging it first?
There is a "Power Good" signal involved with ATX and the voltage regulator on the board, but I don't know any details on how that whole scheme is designed to work.
I wonder if this could be a failure in that area - but I don't know if these are the correct symptoms (runs for a few seconds then turns off).
Depending what's wrong, it's possible this board is overvolting the CPU or maybe other hardware that's attached. Don't plug anything into it that you consider valuable.
I wonder why it stopped beeping - try reseating the CPU, slot-1 is flaky. Not to be too paranoid but if there's an issue with the Vcore regulator then there's also the possibility the CPU has died.
