Can i get some help please.

So I turned of my pc at around 4 this morning playing pubg and some Wildlands. Let it do and update and turned off.

This afternoon I turned on allowed it to finish installing the update for Windows. Then next thing you know... Off. I tried several times rebooting it.

I checked my mobo manual and it shows you on a side the 4 EZdebug LEDs and it was stuck on CPU. I took it off cleaned off the cpu and then checked the pins where ok.

I put it back together and now my CPU spins (whilst still being lit up on CPU error) . Also I can turn it on by power button, but to turn it off I have to switch off from back and pull the plug.


I have reset CMOS and re-seatted it. I have took it all out and put on my mobile box to assemble it out of case, I re seated every component

CPU is a ryzen 5 1500
Mobo- MSI B350 tomahawk
Ram 2x4 corsiar ddr4 3000MHZ
Gpu windforce gigabyte 970 4gb
Pau EVGA 600W

My mobo CPU and ram are all new. My GPU and PSU are a few years old.

Start with the following link:

https://www.lifewire.com/power-supply-unit-2618158

And for even more detail:

https://en.wikipedia.org/wiki/Power_supply_unit_(computer)

Overall, there are multiple components and circuits involved. One part can fail and others will continue to work.

Here is a link to help with testing:

However, if you have never done such things or worked with a multimeter do find someone to help.

First:

"now my CPU spins (whilst still being lit up on CPU error)". You do mean "CPU fan spins"..... correct?

PSU would be my first suspect. Will probably pass the paperclip test but perhaps not some of voltage tests.

Test the voltages if you know how or have a knowledgeable family member or friend who can help.

Otherwise, you still have the option of replacing the PSU directly. Purchase or borrow perhaps.

To me it sounds like software corruption within the Windows OS. Don't know what version of windows your running but you may want to try Hitting the F11 key on boot or inserting a Windows boot disk and powering on to try a Windows repair or a restore from a recent restore point before the Windows update.
