Question Peripherals shut off after installing new CPU (but PC stays on)

[rsguli]

Hello, so I upgraded my CPU to a Ryzen 5 5500 and ever since I updated the BIOS and reinstalled Windows 10, I have my mouse, keyboard and monitor shutting off. However the PC stays on. The power button doesn't work either so I have to manually unplug it. I installed AMD chipset drivers and tried to look for other solutions online but nothing worked. Finally I decided to test out a Linux live USB to see if the problem persisted and it did. So now I'm not exactly sure where to go from here. I have a 650W PSU so I assume that's enough for it? I'm not sure if something is loose or there's an option in the BIOS I must toggle. I don't really touch anything there so maybe some settings changed after I updated the BIOS. Also worth mentioning, everytime I enter the BIOS it says CMOS has been cleared. And ever since before upgrading, the PC has struggled syncing the time and date. Not sure if that's relevant or if it's a different issue. Mobo is a Gigabyte x370 Gaming K7 and GPU is a Radeon 5600XT.

I'd appreciate any help and please let me know if you need more info.

check if the motherboard is contacting anywhere where it shouldn´t with the case. breadboard it outside the case on a non conducting surface (e.g. wood/table)
replace the cmos battery, check if the battery plus is visible while installed
which 650Watt PSU is it exactly?

Ok, I will try that
It's a EVGA 80+ Gold I believe

You say that both before and after your upgrade the CMOS memory was NOT being maintained. So the battery for that is not providing power. Check three things.

1. Look at the CLR_CMOS pin pair on your mobo at bottom front. There should be NOTHING on those pins - no connection between them. Shorting these two temporarily will reset your CMOS system to factory default.
2. Did you remove and replace the battery (about bottom middle of the board)? Check whether it is in place securely and the CORRECT side out!
3. Check whether that battery is already "dead". The fact you had persistent trouble with the clock before your upgrade suggests that battery needs replacement.

If you remove the battery for whatever reason (whether you replace it or not), BEFORE it has been re-installed do this sequence.
(a) with no battery in the holder, and your system totally turned off, short the CLR_CMOS pins for a few seconds (wire or screwdriver tip). Remove the short and install the battery right side up.
(b) Boot into BIOS Setup directly. From the Main Menu (p. 23) choose Save & Exit from the top menu bar to get to the Exit Menu (p. 36). There choose Load Optimized Defaults. This will load a complete set of factory default settings for stable operation. Then choose SAVE and EXIT SETUP to reboot, and go again directly into BIOS Setup.
(c) Go through the Setup screens and find any items you know need to be changed, like the proper boot drive unit and sequence of boot devices, choices for start-up from keypress, etc. When done, go through the Exit Menu again and SAVE and EXIT. This will save your new settings and the system will boot up.

This should give you a stable operation on booting. If the battery is good, your system should keep those settings and you should have no problem with date and time.

Got it. I'll try to purchase a new one today. I never once replaced it so I guess it makes sense it's now dying. Also, these shutdowns have been happening quicker lately. Before, it would happen after an hour or two. Hopefully this is it. I'll let you know. Thanks!

Nope. That did not solve it.
