s5-1554 Dead - power supply?

HP Recommended
pavilion slimline s5-1554
Microsoft Windows 8.1 (32-bit)

Computer found dead.  Tried start button, no response.  Followed hp troubleshooting guide: power supply has solid green light, and when paper clip placed across p1-17 and ground, power supply fan came on.  However, when reconnected and push start button absolutely nothing happens.  Once, all fans started to spin up for about one second, but stopped.  Troubleshooting guide says if power supply fan comes on when the p1-17 to ground connected, the power supply should be good, and should then consider motherboard, memory, other causes.  However, I'm skeptical.  My gut still says it is the power supply.  

 

I have an older computer that died but has a good power supply that wouldn't fit, would it work to connect to see if it would power up just as a test?  Other thoughts before starting to swap out parts as diagnostic?

Grumpy44, welcome to the forum.

 

I agree with you that it could be the PSU.  I have heard of PSU's working using the paper clip, but still not being good enough to power the computer.  If you try to use your old PSU make certain that the ATX Power connector is correct.

Connected old psu to test and machine fired right up. Thus, even if the psu has a solid green light and the paper clip jumper procedure gets the fan running on the psu, the psu could still be bad. Ordered replacement, so hopefully will work.
