Why does this happen?

Quite often I have to turn the psu switch off for a couple seconds and switch it back to power on the pc. Idk why it started doing this and there occasionally times when I don’t have to do it.

At first I thought maybe there’s dust in the connection so I took all the cables out and dusted and it still did it. So now idk :thinkquake:

Looks like PSU is failing, but I'd double check PSU connections on motherboard. Oh, and of course PSU plug at the back.

Have you tried turning off the power switch for an entire night, just to see if it helps any? It sounds more like a capacitor issue of some kind than a PSU issue to me.

I had this same issue with my PC. Wouldn't boot right the first time after shutting down, and the BIOS would reset. I tried updating the BIOS, changing my OC settings for memory & CPU, etc. but nothing worked. Swapped to a different system but I continue to use the PSU and it works fine so it could be an issue with the board or CPU

I dont think its the PSU, all cables are plugged in. I have not tried that, will give it a shot My bios doesnt reset, it didnt always do this. I feel like its more likely the board cause it was an open box buy. and ever since switching to it from my previous B450 Tomahawk ive notice some micro stutters that happen every so often the board is the only used part in my pc aside from the PSU which ive had for 3 years now with no issues.

They are saying that the PSU itself is having issues, not the cables

I'm not saying you also would have your BIOS reset. I'm just saying I had a similar issue where my system also happened to reset the BIOS when it failed to boot

You said you updated the BIOS and the chipset drivers to the newest versions? Microstutter soudns like the BIOS issue that AMD fixed through BIOS updates.

Doesn't matter what board it is Updating the BIOS and chipset are very much recommended

Ill do that but i havent noticed much micro stuttering recently, my main issue is the just the pc not powering on until i flip the psu switch off and on

Could also be a BIOS update or chipset version issue

Definitely update the BIOS/chipset. And try what I outlined. If that doesn't work, then yeah, either a faulty motherboard or faulty PSU are the most likely culprits. If a computer has issues and it's not RAM-related, which is #1 culprit, it's usually PSU/Mobo stuff >.> @JayDoubleUAye Since you seem to be checking semi-infrequently, I'll post some questions and then what to do depending on the answer, and reasoning. So you could go forth without waiting for another back-and-forth. 1. Start with updating BIOS and chipset drivers. This is always good. 2. If you just press power multiple times, does it work, or do you have to go to the power switch on the rear? Cause if just pressing power multiple times works, it might even be something as innocuous as the switch itself being faulty. 3. What happens when you press power and it doesn't work? Is the computer screen black but the PC "turns on"? From the video it seems to not be the case, but if that is the case, then BIOS (voltage/power) settings could very much be at fault. 4. If you do indeed have to turn the power switch on the rear off every time this happens, and if the computer entirely doesn't power up, which seems to be the case, do the following: 1. Try swapping your PC power cable, and maybe try connecting it to a different socket, preferably a different phase if you live somewhere with a multi-phase electric, to determine it's not a problem external to the PC. 2. Do what I said, by turning off the rear power and even potentially taking it out of the socket for a night, in case there's some capacitor issue. But this will only really help identify it, which is less useful if the issue is intermittent, and still leaves you needing to find whether it's the PSU or the MoBo that's faulty and replace them. 3. What's your PSU's wattage, and what's your CPU + GPU combo? It's possible that your PSU simply hit the limit, especially as it's aging. Try removing unneeded USB devices, turning off your RGB, and see if it makes a difference.
