Hey guys I urgently need help as this has been an on going issue for a few days now. I will give the full story of what happened leading up:
PC was custom built by myself back in 2020 (specs will be listed below) has been running with only minor issues appearing over the last few years but mostly stable.
A few days ago I was playing a game, stopped to watch something while I ate with both the game and video I was watching running. Finished eating and went downstairs for less than 2 minutes, upon returning I find that my PC is 'off' but not entirely. My keyboard lights are off, no input on the monitor, my headset docking station lights are off. However, motherboard lights are on, RAM lights are on and power button LED is on.
I thought, okay I guess it has froze or rebooted itself for whatever reason. So I wait a while and nothing happens, it doesn't do anything. So I press the power button, nothing. I wait a little bit then hold the power button, nothing. I hit the hard reset button, nothing. At this point I'm a little concerned as I have never had any PC lock up to the point the hard reset does nothing.
Finally, I cut the power to the PC and it turns off completely. I power cycle and then restore power and the lights remain off like normal. I hit the power button and the PC lights come on again but once again, no post, no boot up and it now refuses to turn off again with the power button or hard reset.
Things in which I have tried:
-I reseated and replaced all of the RAM sticks with known working RAM.
-Installed a fresh CPU of the same type as I first of all thought my CPU died so this isn't the case as the new one has the same symptoms.
-Reset CMOS and had the battery removed.
-Took the GPU out to see if it would at least post without it, no changes.
-Took out all RAM sticks and attempted to boot to see if any post codes would show, no changes.
Extra information:
After a few attempts of restarting I noticed that when I first of all turn the PC on after cutting the power it seems to attempt to boot but then does nothing as the fans begin to move but then immediately stop and I see the post code LEDs light up but then immediately disappear. Resetting the CMOS (my mother board has a built in trigger at the back) also makes it power off like cutting the power.
A few weeks to a few months ago I started getting an error about the cpu reaching maximum temps and forcefully shutting down but this was a false positive as it never reached anywhere near those temps when monitoring it. This error did not happen frequently and would primarily happen when running one particular cpu intensive game.
At first I thought my CPU had died but as I have now replaced it with a fresh one and still facing the exact same issue, I'm now under the impression that my motherboard or PSU are the issue.
I'm hoping they haven't failed as the PC can still hold its power and the motherboard appears to kick into life during the first second of trying to boot.
Has anyone ever experienced anything like this? I don't really want to take another shot in the dark and purchase the wrong part again so this time I want to be more thorough.
I don't have another motherboard or PSU on hand, I have several GPUs and RAM sticks to use as backups.
Specs:
Motherboard - X570 ROG Crosshair VIII Hero
CPU - Ryzen 9 5950x
RAM - 2x 32GB Corsair Vengeance DDR4 3600Mhz
PSU - Corsair AX1200i 80 Plus Platinum 1200w
GPU - Founders Edition NVidia RTX 3090
NVME - Samsung EVO Plus, 2TB and 1TB
Case - Corsair Crystal Series 680x
Cooler - Corsair H115i Pro XT
If you need any additional specs or information please let me know. Any help would be greatly appreciated.
