Question Asus Z97I-PLUS powers on, spins CPU fan for a second and then stops, does not POST ?

Hi,

I've had my Z97I-PLUS custom build PC for about 3 years been working fine; last year it switched itself off and shows similar symptoms...Pressed Power button On, fan spins for a second and then stops, PC does not boot. So last year I removed the CPU cleaned up and applied new thermal paste and reset CPU - this worked so I just put it down to must have been over heating and thermal paste was wearing out.

Last week (a year later approx.) I went to access the PC and it was already powered off, tried to power on but got stuck in the same loop "Pressed Power button On, fan spins for a second and then stops, PC does not boot." So I decided to do what I did last year which was clean the CPU, thermal paste and then reset CPU with new paste - this time it did not work, PC would not boot and is stuck on "Pressed Power button On, fan spins for a second and then stops, PC does not boot."

SPEC:
MB: Z97I-PLUS
CPU: Intel i5 CPU
Memory: Corsair 6GB (single stick)
HDD: 1 TB Samsung SSD

Removed Ram alternated sockets made no difference still the same issue, any ideas anyone ?

Could be the PSU needs replacing, that never occurred to you even though it's related to your problem?
What make & model is it, and how old?

Tried CMOS replacement made no difference.

PSU is working as I can see green light is lit up on motherboard.

I was asking you for PSU make. model & age, not the motherboard which I already know from your specs.

Just because the CPU fan (or any other fan) works is no guarantee that the PSU is okay under full load.

System is built on mini-ATX using case ANTEC ISK1110

Attached images of PSU, I went out and an purchased another replacement power supply, still the same issue.
