Tried methods:

1. Checked the PSU and its running fine (by wire short method)
2. Tried cleaning the RAM with eraser , switched slots tried with different RAM.
3. Removed CMOS battery and placed it after some time (cleared the CMOS)
4. Connections are correct.

What I observed was the blue light in front panel was too dim , barely lit.
Might be a motherboard issue but can't confirm. Help with This please ;__;

was it working before? or new/upgrade?

The psu paper clip test can only confirm a dead psu, not the proper operation.

I might suspect that your psu is the culprit.
See if you can't test with a known good psu.
Intex is a very cheap unit that may not be supplying sufficient power.
Past that, it may not have the protections to keep from damaging all your other parts if it should fail under load.

Buy a quality replacement that will last you a long time.
Seasonic is always good.

PC wasn't used for a long time (probably 1-2 yrs ) tried turning on but it didn't so cleaned it checked the connections and this problem occurs.

Alright but how do I confirm if its the mobo or the PSU?
Better to confirm before investing for a new power supply.

Borrow a known good psu to test with.
That is really the only way to tell if a psu is good/bad.
You should probably replace that psu regardless.

Buy from a shop with a good return policy.
Expect to pay a 15% restocking fee if you decide to return it.
