Cleaning the dust off the PC did not make any difference.
Recently, i noticed erratic microprocessor temperature readings & i suspect their role:

1) My desktop PC failed to boot (no BIOS/POST messages, no HDD activity, no monitor signal)
2) Replaced CMOS battery (didn't disturb anything else) - PC ran fine for 3 days
3) again, failed to boot
4) removed one RAM stick (didn't disturb anything else) - PC ran fine (a bit slow)
5) replaced the same RAM stick - PC failed to boot - again, removed the same RAM stick - PC ran fine
6) held the same RAM stick in slot using one hand (touching just the edges of the stick) while switching on the PC - EPIC STUPIDITY !!!
7) the PC booted but with the microprocessor fan running wild ever-since
