PC sometimes won't turn on until I unplug it from the wall for a 30 seconds or so. Faulty PSU?

Just like in the title my PC has an issue when it won't turn on. Power button does nothing, fans do not spin, PC is completely dead. First time it happened was when I put it to sleep, sometimes it wouldn't wake up so I just avoided putting it to sleep as a temporary solution that become quite permanent... Simple power off worked...

hypertown OP ,

I have some very old no name PSU but it's like 250W. Now GPU can draw this much power alone so my best bet would be buying new. With the option to return it might be worth a shot. Thanks!

hypertown OP ,

The question is which one on which component :P

hypertown OP ,

I thought about it but idk if it'd be safe to remove 24 pin while plugged in. I can't disconnect it though as after unplugging it works just fine.

hypertown OP ,

I might try to disassemble PSU at some point to check since I don't see any on GPU or Motherboard.

(Also I know it can be dangerous but I know my way around high voltage from previous work so I should be fine)

hypertown OP ,

In that weird can't power on PC state or it doesn't matter?

hypertown OP ,

I don't have any hubs. The only thing I bought recently was 4x SATA to PCI card. But it worked ok for quite a while so this shouldn't be the culprit?

hypertown OP ,

I was more worried about frying the motherboard but I guess it's not entirely impossible to blow up the PSU...

hypertown OP ,

True, usually when you work with high voltage you make sure that everything is unplugged and safe. It's common sense and that's why even though you should call an electrician to change the light bulb nobody will tell you to not do it yourself. PSU is not that simple though. Capacitors can still hold a charge. Unless you got trained for working with high voltage you definitely shouldn't tinker with the PSU.

hypertown OP ,

I always thought that PSU testers were way more expensive but it's good to know you can buy them relatively cheap. Honestly I'm curious if such a tester would detect anything. Currently the PSU works just fine under heavy load (CPU + GPU stress test). It only happens when I turn off the PC or put it to sleep so low or little to none power draw.

I haven't seen any bad caps on the GPU or motherboard so I'll see on the PSU (obviously with caution).

With GPU it's an easy swap so I once exchanged GPUs with my friend to see if GPU is causing crashes (it was RAM btw) but with PSU I feel it's a lot of work to unplug everything so I don't want to bother them too much. I ordered an MSI 800W PSU. I have two weeks to return it if I want but your idea of having a spare is a good one.

hypertown OP ,

Wow amazing guide. I'll try testing with a multimeter for now but that PSU tester looks very handy. Maybe I'll buy one someday.

hypertown OP ,

Light flashes and fans move for a fraction of the second but isn't that normal? I always do that when I want to quickly discharge caps and swap some components without worrying about shorting something.

hypertown ,

In VM on FreeBSD ofc, right?

hypertown OP ,

:any

I don't know if it has a name but it's basically a sponge cake with custard cream topped with gooseberry jelly mixed with apple slices. Also it's sprinkled with roasted coconut flakes.
