Default ASus A7N8X-LA - Powers on, but no boot (solved)

After replacing the battery i got this board to boot.
Went back to it a week later and only the cpu fan spun after powering it up
So i changed RAM, and blew out the slots to no avail.
So then changed the psu and noticed that the keyboard lights blinked briefly (which they didn't do before)
Tried again a few times and no keyboard lights.
The fan would occasionally stop a few seconds after turning it on.
So felt like that it was doing what it was supposed to do, so i took the heatsink off, and it was dry underneath.
Put new paste on, and it booted first pop.
It seems that the CPU 'shuts down' but the fan keeps going - which can be quite misleading, because i thought that when the CPU 'stops' due to overheating that the fan would stop as well.

Repasting was just a coincidence I think. Or there may be a bad contact in the CPU socket and taking off/putting back on the heatsink did something.
No sign of bulging capacitors? (they could still be bad though)

OK - yes, i did also remove the CPU and give it a scrub with a toothbrush and dishwashing liquid. So maybe that was the problem - there was a small area of whitish mould(?) on one corner. Now i'll never know
No bulging caps - that's one thing that i like about it - zl and mbz.
Coincidentally, it did start playing up (turning on and off by itself)- but that was due to a faulty power button, that i fixed with a wd40 type aerosol).
