Good evening, I hope you are doing well. For some time my pc had trouble waking up from a sleep mode, I had to unplug it and then plug it back in again, then it got worse, it was doing it more and more often and sometimes it just wouldn't turn on. Tonight, it almost doesn't turn on anymore, just letting me hear a little click of the power supply and a very brief rotation of the fans without light or anything. When I try to turn on the pc again nothing happens but when I unplugged and plugged it back in it makes the click. I did clear CMOS, reseat connectors, ram and GPU but nothing works. I sometimes get it to boot and there's no apparent problem it fonctions normally but once I put it in sleep mode or turn it off, it's when it gets scary. This doesn't happen when I restart the computer. If someone could help me it would be very nice, thanks in advance

I just had to RMA my board, it was acting stupid like that a good bit, turned out to be a POST failure without video, and took awhile to show me a DRAM light. Despite two 16GB DIMMs registering with this board at full speed and capacity for a few months and running fine other than the occasional black screen on startup, one of those DIMMs is now in an interim build with a 3600X, doing fine, the other will now halt POST without video. My board was supposedly shipped back to me today, haven't received any notes as to what the problem was.

 

However, I found that the RAM kit I used was not on the manufacturer's QVL list, and none of the kits listed were supported at the same speed (3200) in the same configuration (2x16). So now I have a sort of chicken-vs-the-egg argument.

I don't badmouth others' input, I'd appreciate others not badmouthing mine. *** More below ***

 

MODERATE TO SEVERE AUTISTIC, COMPLICATED WITH COVID FOG

 

Due to the above, I've likely revised posts <30 min old, and do not think as you do.

In my case, I think unsupported RAM in an unsupported capacity / configuration might have damaged the board, which in turn damaged the memory. Either that or the memory was flaky from the word go. So what I'm saying to you is, it could be RAM, and it could be the board. Do you have debug LEDs? Are they showing anything unusual?

I dont think ram can damage the board, at most it would just be unstable, it should work perfectly fine with xmp disabled or with reduced speed

I have some but they don't light up when the PC doesnt start. Also, I overclocked my ram for a while but didn't see any issues until now and putting it back to xmp didn't do anything. I'll have to order new ram anyway so I'll try with another kit but I kinda doubt it's ram. Do you think it could be CPU ? Like the mounting coming loose or something

Turn off fast startup, that is likely causing some sort of issue.

 

Edit: Please list your system specs, I forgot to ask for that.

B550i rog, R5 2600x, cooler master v650 sfx, crucial ballistix tactical tracer RGB 1x8gb (yes I know) Rx 480 nitro. I built this system more than a year ago and it worked fine

Update : 

I Took the ram out and it booted 4/6 times, changed slot and booted 2/4 times, still no clue 

nds like a board or PSU issue.

Does everything else turn on, just no boot? My Asus board was failing to POST with no video and I couldn't really see the debug lights without disconnecting / disassembling, so it took awhile for me to determine what was going on.

It boots like 5-10% of the time I turn it on after fiddling with cables and ram and when it does it boots normally

Leave at least the fans connected to the power supply, disconnect the cables from the motherboard and graphics card. Leaving the fans will give some load to the power supply to see if it stays on. Instructions are from Corsair, but that side of the 24 pin is standardized.

I'm not actually trying to be as grumpy as it seems.

I will find your mentions of Ikea or Gnome and I will /s post.

The fan turning slightly then kicking back kind of looks like a power issue. Do you have another PSU you can use to confirm? If the problem goes away with a different PSU, it's PSU. If not, the board has some sort of issue.

Grabbed on old OEM PSU, plugged it in without a GPU (cause no connectors for it) and it seems to work but the odd thing is that when I try with my PSU it still works but not all the time

I had it for over a year but I think it's because it's the V1 of the v650 sfx which has issues regarding it's semi fan less mode. I'm going to RMA it but for now do you think it is too dangerous to use my PC when it boots ? Given the fact that I would provide airflow to the PSU

The existing PSU can certainly create more problems when it goes down, especially since I've seen one blow up and nuke an entire system. If you can run it with the other PSU you referred to without issue, that's a viable interim solution until you get a replacement.
