Check if the SMPS/PSU fan is spinning or not? Is the PC giving any kind of beeps?

no the psu fan is not rotating and it is not giving beeps.....

first of all wats your config?
& which SMPS are you using?

Is it a newly assembled one? If yes, then get it checked from the assembler immediately.
If the PSU fan is not rotating then it is faulty, get it replaced or repaired if it is under warranty, buy a new one if it isn't.

asus mother board

The SMPS can be checked if its okay by doing this:

1. Unplug the power supply cables from the SMPS to ur motherboard.

2. Plug the SMPS to the A/C power supply. Short circuit any two terminals having black and green wires. (The end giving power to ur motherboard) Remember 1 black wire to a green wire.

3. Check if the SMPS fan is rotating. If its not, time to get a new SMPS.

Check the PSU following Tron91's suggestion and if its fan doesn't spin, it's time to replace it. Since it's under warranty you should get a replacement.

My friend had a similar experience.His PC wasnt starting immediately when he swtch it on.It was taking 5 min or so to start.It started after he put a 9400GT to the rig.His config was an old p4,asus mobo etc it was upgraded from an OEM PC.I told him that its SMPS problem and I went to check it.After opening the PC I was shocked; the rig was running in a 200W SMPS What would be the actual out put ? 140-150W? He was playing games in that rig Splinter Cell DA ran fine in that condition :-P.Then a Zebronics 450W Sata Plus was fitted and the prob solved.

200W? that PSU didn't have enough power to blow up also P4 are highly power hungry as made on 90-130nm node.

it doesn't matter. your PSU's fan mechanism is dead. get it checked & than repaired/replaced.

[rohanz]
