I built a PC yesterday with all new parts, i had quite a few hitches and now the system runs fine, except when I turn it off... I have made a video of what happens...

No matter how I turn it off, I have to force the fans & cpu fans to turn off via pressing the power button for 5 seconds after Windows is shut down.

I have googled this and people point to it being a faulty PSU or faulty motherboard, Is there anything I can do to test this before replacing them?

Items in my build are:

GPU: 2GB MSI GTX 660 Ti Power Edition
CPU: Intel Core i5 3570k
MOBO: MSI Z77A-G45
PSU: 650W Corsair Enthusiast TX V2
RAM: 8GB (2 x 4GB) Corsair DDR3 Vengeance
SSD: 120 GB samsung 830
HDD: 1TB Seagate 7200 RPM
CASE: NZXT Phantom 410 Mid Tower
DVDRW: Sony AD-5280S-0B 24x

I would try shutting down in safe-mode to see if that works, if it does then try reinstalling/updating your graphics card drivers and motherboard drivers, to me this sounds more like a system hang than a mainboard or psu issue.

^^^^ agreed. A PSU is very unlikely. Normally PSU problems cause system stability issues, not things staying on. Something is not letting the system fully shut down.

I'm not sure if its that because the harddrive LED stops flashing when i turn it off, so surely that means the hard drive isn't on and it must be a hardware issue?

I doubt its hardware, if you used the supplied driver discs and have not updated the drivers it can cause such issues.

I downloaded update live 5 and installed all the motherboard related updates, there was nothing to do with the bios apart from an app to access the bios screen while in windows, but nothing changed the issue.
