PC stalls for a second before BIOS, then boots normally

[CONVERSION]

Hello everyone.

So, straight to the point.
My week-old build or so has a weird problem when you press the power button. The fans spin for half a second or so, then turns off. If you leave it for 3 seconds or so, it turns on normally and is fine.
System Specs:
Case: Antec GX300 Windowed
Motherboard: ASRock Fatal1ty H170 Performance
CPU: Intel Core i5-6500 @ 3.2GHz
GPU: Gigabyte Windforce 550Ti
RAM: G.Skill Ripjaws-V 4GBx2 Modules
PSU: Antec EDGE 750W 80+ Gold Full Modular

Thanks,
CONVERSION

So I haven't reset the BIOS or plugged it into another room's wall socket, I shall do that tomorrow.

I didn't see that message, I'll do the scan in the morning then plug it directly into a socket.

Sorry for another post, but if it continues to do this stall then I'll take the whole thing to MSY and ask thwm to put the PSU and / or motherboard on their testbench.

Thanks so much for all your help and I hope to get back to you tomorrow with good news.

Good luck with it. I hope to hear good news as well. If anything works pick a best answer so that other people with similar problems can maybe have a solution.

No errors on anything. What's happening is called a false start. Basically a power draw thing. If it can't draw correctly from your house then it can cause that. I've seen them not start at all because too many things are plugged into the wall. You can also try another cord for the psu. That one might be old. Only other thing I could say is to swap the psu out entirely after you try all that and nothing works. I'm out of ideas as we've gone through the entire system quite thoroughly. Only other thing we haven't tried is windows errors. You can try a sfc /scannow in a command prompt you run as administrator.

Windows Resource Protection did not find any integrity violations. The only other power supply I have is in my old Dell Optiplex from about 14 years ago with a pentium 4 and my laptop power brick. I'll try bringing it to anther room and plugging it directly into the wall, will do that now.

Ok, plugged it straight into the wall and didn't fix anything. I might take it down to MSY if I have the time, as school's starting soon. I'm selecting the false start answer as the best answer. Thank you for all your help, I really appreciate it.

Glad to help. Let me know what MSY said. I'm curious as well.

Hello, it's been a while but MSY said they have to kbow for certain its the piwer supply before they replace it. They offered to send it away and replace whatever's not working for $50 but I declined as it would take at least a week, and I need it right now. It has tripped the house's electricity circuit again. I'm thinking of unplugging everything from the PC and checking if it still happens with just the PSU. If so, that's proof that it's the power supply, and they'll replace it.
