Fans work but computer won't turn on

So my computer will not turn on.  It got bumped by a plant that fell over.  What happens is that 3 fans turn on, but the power button does nothing.  I tried unplugging everything external and it does the same thing when I plug it in.  I would expect it to beep for an error for not having the keyboard or hard drive attached.  The machine is an HP Pavilion P6710F.

Any ideas?

unplug the hard drive and see if it will turn on..

If the power button does nothing, it may have become unseated when the desktop was jarred.

Clarification required.

When you press the power button do the fans either turn on or turn off (and nothing else happens)?

No, the power button does not light up and it does nothing if i press it or hold it down. I also checked and made sure it was seated in the motherboard securely. I didnt try to jump any pins, because i wasn't sure which ones.

Data loss can hit a business in any number of ways. In reality, companies should expect to lose data at some point. The challenge is having a plan to recover from such an event.

usually in this case check the memory pieces, remove them and replug them again (one by one)

open the box and check all connections - best remove and reseat each one for inspection

Did you remove the CPU as well?

If not please do so and carefully remount.  Replace any heatsink paste and check that heatsink mounts correctly on top of CPU.
