Hello everyone, good day.

Firts of all, my specs: http://speccy.piriform.com/results/cKQ4pGqZ18k5DrHZscinwFb

This is a problem that I had a few months ago, because of new baby and work my original post closed with no solution (https://pchelpforum.net/t/random-pc-restarts.72921/#post-139905). Until just a wweek ago, my PC powers up to this error LED (ErrorLEDs photo, CPU LED). My PC is not responding to anything besides turning off the PSU, but after the third try every LED starts to blink and then... nothing, it shuts down by itself. So, new PSU, BOOT LED appears, quick fix, but after 6 hours of use (very little gaming) the **** things shuts down itself again.

I don't know if this is a hardware problem or a driver problem, maybe the old PSU made some damage to something, I don't know, out of ideas.

Every time I start the PC the error LEDS blink in order CPU, DRAM, VGA aand BOOT, is that normal?

Thanks for your time.

what are the specs for the new PSU?
Cooler Master MWE Gold 750-V2 80 PLUS Gold, 24 pin ATX, 120mm, 750W

In addition to that I tried changing the RAM slots, working with 1 intead of 2, trying to Power up the PC withouth the GPU, nothing works. If the PC is on, its only a matter of minutes before it shuts off again. Someone told me that maybe the problema is my RAM, 3600Mhz vs the 3200Mhz limit of the Ryzen 5600X... But I dont know.
 
to me, that only leaves the motherboard as the next likely candidate, followed in order, by the memory and lastly CPU.

if it was mine, I'd be taking the whole thing apart and reassembling on a piece of cardboard somewhere.
only reconnect the core essentials needed to POST the PC.
reset your BIOS back to factory settings to undo that memory voltage changes you did.
and as you reassemble, take the opportunity to clean all the components, any contact points they may have, and their corresponding mobo slots.

Hello Bruce, I did the test with every component and connections. I have 4 HDDs, two of the are SSD. Working with just the SSDs everything is normal... Because of lack of time I did not test the other HDDs, but my bet right know is one of those, maybe both... What do you think?
 
if you have left it on long enough, and get no restarts, with only the SSD's connected, then YES, logic would dictate that one or both of the HDD are to blame.
easily tested - add one at a time until the restarts restart (hah!).

OK. False alarm. It worked for ten hours, went to work, now that I'm back, Power switch on and nothing happenned. After that it only responda to turning on the PSU and the machine starts with the same red cpu led and fans. Tríes with another RAM, withouth GPU, withouth SSDs and nothing. Not even the bios shows up.
 
Yes yes. Sorry, got sick.

So, getting my warranty to work on the motherboard was a pain in the ***, so while I wait for it, I got a Tomahawk x570 Max Wifi to test. Everything normal until the same error appeared again, exactly the same. So maybe is the CPU... And I really hope it is because I'm getting tired of this. So, new CPU is on the way... What do you think?
 
while I can't say it is/was the CPU, it's not a component I would have tackled first.
my first crack would have been with the motherboard.
only time will tell. :)
New information.

I bought a new CPU, Ryzen 7 5800X to test the Tomahawk and the Aorus. Same **** problem. Is the 5600X CPU killing the boards? I'm very, very confused... Maybe the GPU? The boards are shutting down withouth it though... This is very frustrating.
 
that's a good, if somewhat scary, find.
wonder what else in the house may have be effected?

but yeah, that's one very good things UPS units do, forget the battery backup benefit, it's the cleaning of the sine wave that really saves the day!

Unfortunately... I'm not done... Now I have an overheating problem with my processor, my cooler is the shitty one that comes with the 5600X... And right now is hot as hell where I live.

Just om BIOS is on 46C... So I tried to play some Halo last night and the thing **** down itsefl, on desktop after that it was on 66C and going down, but then it went off again...

My ***. I'm tired of this :(
 
if the ambient temperature is 'hot as hell', all any fan will do will be just pushing that hot air over the heatsink.

so while a better fan and heatsink may help, perhaps consider water cooling.
but even then, how hot are we talking with the air temp?

66C isn't too bad, certainly not critical, I'd call it high in the average band.
the shutdown may have been caused by the BIOS settings detecting the CPU hit a preset temp range.
check the BIOS settings for what it has in the power profile for triggering events based on temps.

Right now, we are on 30 to 33C, for me... That's a Lot. Another thing I noticed with the CPU temp, while doing nothing it reached to 88C and stayed on 75 for a long time... I'm foing to check BIOS version just in case and I found an option Calle "CPU VRM over temperature protection" with the option to Set it from 95C and above, not surenif this is the right one.
 
for me low 30's is a normal summer day, hell, even in spring and autumn here in tropical Queensland that temp is common!
for example, last night the room temp was 27 and after the PC was on for a while, it reached 39 (southbridge).
I have a wall mounted, wooden, open to the air, custom built rig I did a four years ago.
I added two digital thermometers - one for the ambient temp and one on the SouthBridge as it's not actively cooled by anything and gets rather hot.

whatever cooling system you use, it should keep the processor within, say 20-30C of the ambient temp. any more than that and you are either over-working the system like playing games or you have an airflow problem.

have you changed the thermal paste on the processor?
try leaving the side cover off and blowing a fan into the chassis.
doing nothing and hitting 88 is concerning - have you opened it up and checked the CPU fan is indeed working? (y)
