I decided to clean out my CPU fan as it was clogged, when I assembled everything again it won’t turn on 🙁
It’s an old desktop PC. There are no lights glowing on the motherboard at all, though there is none specifically labelled “power”. Just CPU, RAM, BOOT. None of these light up, not even a flash when it starts.
I have reseated the RAM, CPU, power cables. Removed the GPU to check.
The cord leading in to the PSU works but I don’t have a way to test the PSU itself or the out cables, but I have reseated them at each end.
This PC was working fine before. But with no lights on the motherboard I suspect either the mobo or PSU?
Mobo is asrock x570 PSU is silverstone 650w strider gold S series
Any help appreciated!
Edit: I made a new post asking for hardware recommendations.
Edit 2: I managed to get a light on the motherboard, going to buy some more thermal paste and keep tinkering to see if I can get it started!
Edit 3: I never got that light to go again. In the end the comments on the other post convinced me that I had all that I needed for what I wanted (no upgrade needed), so I changed tack to seeing how to fix it. I had suspicions about the power connection still, so I bought a cheap PSU and tested it, no change. Then I bought a new motherboard (also a pretty cheap one, the cheapest that had what I needed and was also in a local store) and in the end that was the issue. Everything is up and running again now! Thanks for all the help everyone, you can now settle your bets.
I’ve tried in both positions.
Might sound weird but I can hear a quiet buzzing in the off position (O) and silence in the on position (1). But I don’t have another to check what’s normal.
It’s generally the reverse thing that happen you can hear the buzzing when on and not when off… 😁
That’s why I mentioned it! It seems logical. Normally 0 is off and 1 on, right? I tried in both positions but it buzzes when in the 0 position.
This sounds illogical to me
For the record, I did a paperclip test and the PSU seems fine. 1 is definitely on, 0 off, and the buzzing is when it’s off 🤷. It’s not loud, you can only hear it when held up to your ear.
Is there any chance the buzzing is actually from what you have the PSU plugged into? I think ive had a surge protector that have a buzzing without anything drawing power that went away once something was consuming power.
Definitely the PSU, but it’s not drawing power so maybe the buzzing would go away if the PC was drawing power.
And when you unplug the power it goes?
Yeah, may just be that the PC isn’t drawing power, the buzzing might go if it was.
Mind trying another power socket just to eliminate potential environment problems?
Did it, and also did a paperclip test. PSU seems fine, it’s getting power.
