Computer won't turn on

[PalkiaRock484]

So I'm panicking right now because my computer was working fine yesterday and now the power button doesn't work, when I use the psu testing tool it works fine, and now it's just flashing on and off for split seconds when I adjust the 24 pin.

Do you think the problem lies in the 24-pin connector? You'll know because it will work sometimes or intermittently. I'm not able to tell what you're saying in the question.

No, the power supply works fine whenever I use the psu tester, it might be my motherboard but I don't know what to do about it and I'm panicking because I have a bunch of work to do.

We know that the power supply works; it could be the connector itself. Do you have another power supply that you could swap out just the 24-pin connector with?

No I don't and the psu tester uses the 24 pin so I'm sure that thats not the problem

Is the computer itself dirty or dusty? Additional debris around the motherboard can easily short it out and cause problems like the ones that you describing. Thankfully, most of these shorts don't damage the board given that they are cleared relatively quickly.

The case standoffs didn't exactly match up to the motherboard when I built it, so I tried taking the screws out to further diagnose the problem and I heard cracking sounds. I don't know if that means my mother board is dead because the screws have been like that for almost a year with no problems

Were the cracking sounds electrical cracking (small but frequent pops) or were they stress cracks (cracks made when something is bent or stretched, creaking included)?

Ditto, sorry for the late reply; unfortunately, if they're stress crack sounds, there's a good chance that you've simply been dodging bullets this entire time and that the board's been on the brink of collapse for the time that you've been using it. Sorry to break the bad news.

have you tried to jumper the power on header to turn it on bypassing the case button?

all the layers of the mobo have different layers of electrical runs. if you severed one of those runs from the "cracks" you've got yourself a very nice paperweight.
