PC starts very late or after 2-3 tries

blow air in CPU cooler and SMPS fan

I did something like that with my SMPS (used the blower attachment of vacuum cleaner) and the problem depicted in this thread started only then ..

I guess the motherboard is extremely sensitive to voltage fluctuations. At least that was the explanation which I had resorted to, because the problem disappeared only after changing the SMPS (which was about 11 years old).

My SMPS is just 1 and half year old...but will try...will have to find SMPS to test the system.In case, voltage fluctuation is reason...is there chance of motherboard blowing out? I have a stabilizer though.

Naah. The SMPS itself has adequate in-built protection. It kinda self destructs without harming the motherboard (that is, if something should go awry).

Checkout http://bit.ly/9N5wXf It mentions the presence of a OVP (over voltage protection) on a SMPS.
