Dell optiplex 3060 not booting
I have a modified optiplex 3060 tower (i5 8500)
I am using a 650w 1stplayer PSU with a diy power adapter for the 6 pin port on the motherboard
It was working for fine for 5 months
But when I went to vacation I left it on
and when I came back I shut it down by holding the front io power button
and when I turned it back on it wasnt working
I tried reseating the ram
I have removed my rtx 2060 and am using the i5 8500 igpu
I unplugged all drived and replugged em
I replaced the cmos battery with a new one
I tried using the orignal dell 250w psu
nothing works
I am able to boot into windows with a trick
I unplug the front io power button and then turn on the psu which leads to an error which when pressing continue then boots into windows 11
and when I plug the front io power button back I am able to use it to shutdown windows
but when I press it again it doesnt work.
and to boot again I have to do the same thing.
No idea how to fix this. Ive tried everything that ik.
I used this to make my custom adapter

it seems your power button is acting strangely but not dead. this occurs with the oem psu too so it is not issue with the new psu.

when you unplug the power button, are you able to power on pc and boot into OS using the psu consistently despite Windows error?
what we know from other user is that with a 24-6 pin adapter with standard psu, the psu stays on after you shut down Windows.
The power button merely sends a logical signal to psu to PS_ON, so if the psu is on all the time you might skip the button for now.
”Power On is the signal from motherboard to PSU to power up ”
I would get a commercial 24 to 6 adapter on Amazon just in case the DIY has some funky quality issue you are not aware of. I would trust the off the shelf adapter in long term use, even though your home made one worked before.

@redxps630 I wont say it boots consistently sometimes it doesnt. but most of the times it does boot fine without any windows errors only bios error. My psu does stay on after I shutdown the computer but I dont beleive the psu is a problem here as I stated the orignal psu works fine.
The problem is even if I am able to boot into windows. after I shutdown I am unable to boot it back. And I have to turn of the psu unplug the power button and then turn it on again and the pc boots after 1 minute and a couple power cycles

Speaking unplugging power button and using test button on PSU to boot, have you tried that with the power button plugged in? I can't help but be curious.
May be try replacing the power button? Otherwise, I wonder if it's an MB issue.

@bradthetechnut What test button? What happens is when you press the power button on psu it boots the power button lights on but then it turns off and nothing happens, and when I press the front io power button nothing happens it doesn't boot. I tried shorting the headers and it didn't work (I am 100% sure I was shorting the correct two headers). I then unplugged the front io power button restarted the psu and it boots in the bios hardware error and when you press continue it boots into windows no problem, I plug in the front io power button again and hold it to shutdown the pc and it works, but when I use it to turn it on again it doesn't boot. The power button is fine I'm pretty sure the mobo is messed up. I tried reflashing the bios via windows replacing cmos bat and all

If you have not yet cleared CMOs settings via motherboard jumper, it is worth doing it now. The original posting said replaced CMOs battery but did not mention clear CMOs via jumper. When power button acting funky it could be due to a corrupted CMOs settings not necessarily clearer by new battery.

Instructions as to what redxps mentioned: How to Perform a BIOS or CMOS Reset and Clear the NVRAM on Dell Computers
And please never mind what I said about a test button being on the PSU. I got mixed up with one of your sentences and thought you were using it to get the thing to boot.
