Porco Malo

Hello friends, I've faced the following issue for about a month now: Powering on the fans turn on (spinning at higher speed than normal), as well as the lights on the GPU and RAM turning on. But no POST and screens stay blank. Pushing the reset button has so far always resolved this and after that the boot-up is normal. I'm getting a bit worried, is my motherboard about to fail? In normal operation there are no stability or thermal issues, everything is as usual. I've updated to the newest available BIOS. I'm thankful for any ideas or tips you might have. EDIT: I just remembered the first occurrence - when this happened the first time, after pressing reset to get the PC to boot, I got the Windows 11 splash screen trying to convince me to install it (Windows update had downloaded something for it in the background apparently). I declined, cleared the Windows Update cache and disabled the TPM in BIOS to prevent the same happening again. I don't know if that's connected to the POST issue or not.

This took quite a while, I ordered a Seasonic Focus PSU to use for testing, and the first order got canceled for some reason – now I finally got it, and looks like the fault was indeed in the Corsair PSU. All the issues are gone now. Really happy I don't have to start swapping the motherboard! Thanks again for the help! There's the PSU tier list thread here – do you know how the data ends up on that list? I feel like I should report somewhere the fault with the other PSU (other than RMA'ing it to where I bought it).

That's true. I'll look into that too. One more thing I thought of - my GPU doesn't have a separate power connector, so it's just powered through the PCI-E slot. If this crashing would be PSU related, in a situation where power use sharply goes up, wouldn't it then just as well happen when I for example launch the CPU test on Cinebench or encode video etc (I've done both multiple times)? I mean, isn't it all the same kind of load for the PSU, when it just feeds the motherboard (not for example different rails feeding M/B and GPU)?

Thank you so much guys. I cleared CMOS now via jumper but the issue remains. As one extra detail the issue seems to arise with close to 100% certainty in cases where I wake up the PC from sleep - seems that if it has been switched all the way off, the chance is much lower. Could this in fact point to something in the PSU? At least wattage wise I thought I would be very well covered with the current PSU but I guess I will just have to buy another one and test the system with that. I don't really have anyone nearby to loan one from. God I wish it's not the motherboard, that's gonna be a real warranty hassle, this one is a customer return item, sold 10 months ago... I actually got this one because I thought it was one of the better ones, I had no idea a lot of folks had problems with it.

First of all, I'm a long time listener, first time caller. I've tried to find similar cases in several places, but haven't figured out how to pin down what is wrong in my system. This is a few months old build, where I've had the same problem come up several times a week. Symptoms: Everything else works fine, but on launching PUBG (which I almost exclusively play), about 50-70% of times the PC powers down before reaching the lobby screen (no BSOD, just power off). It shuts down to a state where the power button is unresponsive, while RAM is still appears to be powered (RGB on RAM is still on like in sleep mode), and I have to switch the PSU off and on to be able to boot up the system. System has shut down similarly upon launching the OpenGL test on Cinebench R15 (which lead me to suspect it could be a GPU issue). A few times (less than 1/20) the system has similarly powered down right after booting, when displaying the logon screen. Sometimes, less than once in two hours, the screen flickers for a few seconds in 2D/desktop use Also: This typically happens 2-4 times in a row after which the game has reset to default settings (graphics settings all the way down to low, key mappings to default etc.) I have been in contact with PUBG support and as per their instructions reinstalled the game, reinstalled the GPU drivers, and done a Windows services fault seeking by switching all the non-Microsoft services off and on with MSCONFIG (I was unable to reproduce the issue with this, which again led me to believe this could be HW related). When the game successfully launches, it very rarely crashes during gameplay (either with GPU stock clocks or overclocked to core clock +150 MHz & memory +450 MHz) – the in-game performance is just fine I have tried repeatedly launching PUBG with GPU under-clocked (core clock & mem) – this doesn't make a difference I used the same GPU for almost a year in a Dell Optiplex, without this kind of a problem I don't really play any other games with this system so I can't say if launching some other similar game would be different. I would greatly appreciate any help in fault seeking, I unfortunately don't have any spare/replacement components that I could have used to pin down a possible HW issue. I've exhausted all my own skills Thank you in advance to anyone taking the time to read this.
