Configuration:
MoBo: Gigabyte GA-B250M-DS3H
Processor: Intel Core i3 7100, 3.9 GHz
RAM: G.Skill 8 GB DDR4-2400 MHz (single stick)
SSD: SanDisk PLUS, 120 GB
GPU: Intel HD 630 (Internal)
PSU: Corsair CX 450
Previous PSU: Seasonic S12II 520W
OS: Windows 10 Home
Usage: MS Office, Casual browsing, No editing, No gaming
System Age: 4 years
With the previous PSU (Seasonic) the PC already had a long-press problem, but was able to start within 2 minutes of long press.
Recently, the PC got stuck in a boot loop. I replaced the PSU with a brand new Corsair CX 450. The boot loop problem was resolved, and initially the long-press issue also seemed to have gone. Within a few switch-ons however the long-press issue returned. Now, it needs to be kept pressed for nearly 4-5 minutes before it turns on.
There are no issues once it turns on - moves effortlessly to Windows Start and functions normally thereafter. It sleeps normally too, and wakes up when a key is pressed. The only issue is the extra long-press start.

What I've tried so far:
- Cleaning out dust (wasn't much) -- doesn't work.
- Shorting the switch pins on the MoBo -- doesn't work.
- Changing the RAM slot -- doesn't work.
- Removing an extra HDD -- long-press interval shortened briefly, but increased again next time I switched on.
- Switching OFF the PSU, waiting, switching ON -- time interval reduces slightly (from 4-5 minutes to 1-3 minutes).
