Question PC wont turn on after being unplugged overnight ?

[Goos3]

After being unplugged overnight my computer takes a while to boot. This morning I plugged it in at 7:15 pressed the power button and it turned on by itself by 9:45. I think this started around 2 weeks ago. I have replaced the cmos <battery> but it did nothing. I tried to jumpstart the computer with a screwdriver but it wont turn on unless I wait a while. The psu turned on when i tried the paper clip test but after plugging it into the motherboard and pressing the power button it wont start.

system specs:
asus ex a320m motherboard
Amd ryzen 3 2200g
Western digital WD10EZEX 3.5 inches 1TB HDD
Western digital WD7500BPVT-22HXZT3 150 gb from an old laptop
Seagate ST2000VM003 2TB
Thermaltake Smart SPR-0500 80 Plus PSU 500watt
3 Team Elite Plus Memory 4gb Ddr4-2400
windows 10

Does it take 2 hours for the power to come on or for the boot process to finish? Unplug all the hd except for your os one. See if this changes anything.

It takes a while for it to turn on. Whenever I press the power button it doesn't turn on unless I wait. There is this little rgb light on the motherboard which I assume it that it still gets power
I unplugged all of the HDD except one but still no change

Try replacing the motherboard battery.

Try replacing the motherboard battery.

That was the first thing I did when this started happening.
I have recently found an old computer and swapped the PSU. My current PSU worked fine and the older PSU did not work when plugged into my PC. So I think that the problem is either the motherboard or the CPU. Should I just buy another motherboard at this point or is there a chance that the CPU is broken?

How old is the motherboard? Chances are the last thing wrong with a computer is the cpu being bad. It does happen but it is like 4 out of every 30k. So I doubt it's your cpu. Which drive has the os on it?

I got the motherboard January last year and the os is in Western digital WD10EZEX 3.5 inches 1TB HDD. Also the problem has gotten worst. I wasn't able to open my PC at all yesterday

Ok so unplug all the drives including your os one, then leave only one stick of ram in and see if it starts.

Just tried it and it still won't boot. Putting it in different slots didn't seem to work either.
Also I forgot to mention when I tested my Psu with the old computer the other day,I completely stripped my PC. I plugged my psu into the wall and only had that connected to the motherboard. Still didn't work

Yeah time for a new motherboard.

Where do you live your motherboard may still be under warranty?

 

[Goos3]

I bought it online and unfortunately it only had a 1 year warranty that ended last January.
