Windows 10: PSU works on one motherboard but not the other

So I just finished my build. I'm on Windows 10 64 bit. Specs are:

• Intel Core i5 4690k @3.5ghz
• Silverstone RVZ02 Case
• Cryorig C7 CPU cooler
• Crucial Ballistix 16gb 2 x 8b Ram
• mitx Asrock Motherboard - ASRock Z97E-ITX/ac LGA 1150 Intel Z97 HDMI SATA 6Gb/s USB 3.0 Mini ITX Intel Motherboard - Newegg.com
• Western Digital Caviar Black 1tb
• Gigabyte GTX 660 2gb
• Corsair ATX 750w PSU - CORSAIR TX Series CMPSU-650TX 650W ATX12V / EPS12V SLI 80 PLUS BRONZE Certified Power Supply - Newegg.com

So I shutdown my pc lastnight then flipped the psu switch off, this morning take a crack at disassembling the riser card from the pcie slot, reassemble the gpu and riser card again, then go to turn the system on and........ nothing. I disconnect the riser and gpu, disconnect the hd, ram, etc, still nothing. Put the PSU in my old case hook it up to the old motherboard, boots up instantly.
I should note that the case was open with the motherboard exposed as well as the psu sitting on my desk until i get an sff corsair 450w. Before this i was having trouble with display drivers not working properly on my gpu on this build. The gpu and hd and psu are from my previous build and they all worked together flawlessly. So I am not sure if this is from the psu or the motherboard. I should also note upon powering off the psu I heard a faint buzzing sound.

Password works on one machine but not on the other

I have 2 machines one running windows 10 the other windows 8. The one running windows 10 ran fine until I started updating the other from 8 to windows 10. Now the other machine keeps saying the password is incorrect even though i can use the same password
to login to the same Microsoft account on all my other devices. What can i do to fix this?

Make sure the on off switch from the PC case has not got disconnected from the motherboard.

 

Buzzing sound could be the fan or if it was not mounted properly this is what it could be to. Seems something was not connected as Philc said. If worked on another PC it shows to be working o.k. and 750W should be enough for that graphics card, watts and amps. Going back to display drivers what was thee exact issue because everything was powering up then ?
