Tough to tell, but...

Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems.

Well, you could test them with a multimeter & a 1K resistor in series & see what voltage they are, or replace them, are they the half AA ones?

I don't remember which exact Macs, but some will not even power on without a good one, many just refuse to boot at all.

The original PowerMac Beige G3 series was one that needed a strong PRAM battery or it would not boot.

The Beige G3 came in three variants. Please tell us if one of these matches what yo uahve. You have us guessing right now.

Beige G3 "Desktop":
Beige G3 "Mini-tower":
Beige G3 "All-in-One"
