HP Pavilion A1000 Desktop won't power up

Specs: Windows XP
We have an HP Pavilion A1000 Desktop with Windows XP that won't power up. It worked completely normally until yesterday, when it wouldn't start until the 3rd attempt at pushing the power button. Shut it down as normal, but today it won't start at all.

When we attempt to power up, nothing happens. If we hold the power button in, the blue LED on the power button will blink. There are no beeps, no fans come on, etc.

We disconnected the wires that go from the power button to the motherboard for a few minutes and reconnected, but no luck. We dusted it, unplugged it for a while, etc. We checked all connections we could see comfortably, everything looks fine. I don't think it's the power supply because when we connect the power cord with the supply on the back of the box it clearly gets power and the green LED comes on.

I've looked online for solutions but nothing seems to fit. One solution said to follow the 2 wires from the power button to the motherboard, disconnect, and short them with a screwdriver to see if it turned on. However, we don't have 2 wires, we have 6 (3 bundles of 2 each).

Update: My husband said he discovered the 2 wires out of the 6 that went to the motherboard, tried shorting the 2 corresponding pins with a screwdriver as we read elsewhere to do, and nothing happened.

Another solution said to check the front panel card reader, but as far as we can tell, we don't have one (they're all in the back panel).

We are completely stumped. Any thoughts? Something else we can try before we start buying parts and replacing them?
