Pc Will Not Restart Or Shutdown Even In Bios

Hello, I've just built a gaming PC (not my first) using an MSI MPG z390 Gaming Plus board.

I can get into the BIOS and I can boot into Windows no problem but when I try to shutdown from Windows the system goes through the process and you can tell that Windows has shut down (hard drive light stops flashing completely) but the power stays on so all fans are running and lights on the board are on too.

Also if I enter the BIOS and then "save and exit" or just "exit" it just freezes and does nothing.

When I was installing Windows the system did freeze at a couple of stages if this helps at all.

Any help would be greatly appreciated.

I have updated the BIOS but no change.

Thank you

Ziggy

 

If me, I would pull everything out of the case and assemble the system on a large cutting/bread board and see if it works there. When out, double check to make sure there was no foreign object under the board, or that you didn't accidently insert an extra standoff in the case. A common mistake by the less experienced and distracted pros alike is to insert one or more extra standoff in the case under the motherboard. Any extra standoff creates the potential for an electrical “short” in one or more circuits. The results range from "nothing" (everything works perfectly) to odd "intermittent” problems to "nothing" (as in nothing works at all ). So, you might want to verify you only inserted a standoff where there is a corresponding motherboard mounting hole. This is necessary since cases typically support 1000s of different motherboards.

You can power up the system outside the case by very carefully and momentarily shorting the two-pins on the motherboard that lead to the case's front panel power button. Use a small flat tip screwdriver if you don't have one of these handy switches many techs use when troubleshooting outside the case.

I would also try a different power supply at this point too - to verify yours is good (or the problem).

This is also an opportunity to make sure you connect the front panel switches to the motherboard's front panel header properly.

 

Thanks very much for the advice, I'll give that a go straight away.

 

Keep us posted.

 

Ok so I completely removed everything including the mobo, there was nothing out of place and all the standoffs are placed correctly, checked and double checked the whole thing but no dice.

Could the board be faulty?

 

Yes, it sounds like it could be. I would still try a different PSU, and if using more than one stick of RAM, try one at a time. If still no good, then I would probably return the board.

 

Ok I'll try both, thanks again, really appreciate you time

 

No, still the same so it looks like a dodgy board.

Many thanks again Digerati, happy new year to you.
