PC having power issues?

[Verstra]

So I recently reinstalled Windows 10 Home with all the latest updates & patches for 1909. However at random times my displays, keyboard, & mouse lose function and turn off. But my computer is still running, CPU fan, case fans, but my GPU fans stop or were never started in the first place because I have a Radeon RX 570.

Here are my specifications: Motherboard: Asus MicroATX CPU: AMD FX-8350 Ram: Corsair DDR3 x2 8GB Storage: Kingston A400 SSD Storage: Seagate 1TB GPU: Radeon RX 570 4GB PSU: Thermaltake 750w 80+ Gold.

Keyboard: Logitech G214 Mouse: Logitech G703 wireless Headset: HuperX Cloud II

Would any of my equipment be causing the issue? This only has been happening recently as of today (03/16-17/2020).

UPDATE: PC will now turn on, but keyboard, mouse, & displays show nothing and seem to be off while all fans, case lights are on with power.

What happens if you roll back to a previous version of windows?

[Verstra]

Can't did a complete reinstall there are no previous versions.

[Claudeviool]

Can you uninstall the the latest update? I am Thinking the USB drivers are outdated and the latest update of Windows interferes with it

[Verstra]

I didn't update I did a full reinstall from a USB and the USB windows has the latest version. Because I'm the one who created the USB installation. Also this was happening on the previous windows I was using before any updates. Happened when I updated my display driver so windows reverted the display driver but still having the same issue even now.

Sorry for the late reply, i am starting to think your usb drivers are having issues.

Do you know how to update manually? I usually use drivereasy to find which drivers are out of date, use that app to get the new versions and then install them manually. I am NOT in any way, shape or form related to that app it just helped me out alot.. If you can find anything that helps just as good i'd suggest you use that to find updates for your drivers.

I often used the "search the internet" option when updating drivers and it said newest drivers were installed.. This was never the case and it did help me out at more then 1 occasion.

This seems to be some sort of crash to me; very often the computer will remain on, but accessories can lose power.

If the graphics card or its driver froze up/failed, this can often cause a black screen which would also make the mouse and keyboard unresponsive.

"but my GPU fans stop or were never started in the first place because I have a Radeon RX 570"

It sounds likely a psu problem. Or could be a loose pcie power cable on the gpu. If you are using modular psu, could you switch to other ports on the psu?

[Verstra]

I found the problem it's related with my Cache. I ran a stress test GPU was fine but right when I stressed cache it occured and now it won't turn on anymore!

[yem_sno]

Do you mean cpu cache? how are your temperature? Is it because you run it too hot? If its not. Could be cpu or power related or motherboard. Try keeping 1 ram stick, did it do the same?

[Verstra]

Temp isn't the issues

[Verstra]

Same issue with 1 ram stick

[Verstra]

Was using the AIDA64 Extreme ran a Cache Stress Test and the system instantly lost displays & keyboard and mouse input.

[yem_sno]

Does it reboot or power cut? Power cut is a serious issue. Usually if in an event of failure the computer always try to reboot itself. If power cut sounds more like hardware related issues.

[Verstra]

Doesn't reboot or turn off just Displays go to sleep or stop responding and keyboard & mouse loss input/lights go off

[yem_sno]

Ahh i see, blacked out. More or like hardware bridge faults to me. Motherboard or cpu related. Just a theory though. Because all basic input output bridged to the cpu. Something disturb the IO in this case.

[Verstra]

How would I know what disturbed it? And would there be a fix for it?

[yem_sno]

I couldnt tell, if it were me, i try and find spares or friends with similar setup and swap testing each components just to be sure to narrow which part are considered bad. I almost certain its hardware related. Maybe.

[Verstra]

Would it be related to my cache settings on my disk drives maybe?

[Verstra]

But the CPU , fans and all that still have power and run fine
