Specs: Windows XP, Intel
After starting the computer, the PC light blinks, the fan whirrs for 2-3 sec but after that fan starts to turn off..and the boot up stops right there. No beeps from the computer to go by. No light flashing on monitor & Keyboard. The light indicator next to Power cord port in PC turns ON, when pluged to mains. Can you help? It's a Compaq Presario SR1000.

Apparently Presario SR1000 is a desktop computer.

Answer these:

Was there some event that happened since your computer last worked properly?
Was there a power failure?
Was there a lightning storm in your area?
Did the power supply fail and you replaced it?

Was there anything you did since the computer last worked properly?
Did you make any change to connections, or remove or install any components, inside your computer case?
Did you change which ram you have installed?

If you HAVE NOT been fiddling with anything inside your computer case, and HAVE NOT changed which ram you have installed since the computer last worked properly...

the most likely thing is....

Failing power supplies are common and can cause your symptoms.
Check your PS.
They often partially work, fans and hard drives spin, leds come on, yet you get no video and the mboard will not boot all the way.

Though there was nothing unusual (ie. not power failure etc) the last time when I shut it down, but after that the PC was packed & shipped (from India to HK).

After unpacking in HK, when I tried turning it on, it gave this problem. The CD Rom light would also light & turn off (making some sound from CD Rom). After a while the fuse for the room went off.

Is the AC voltage in India the same as in Hong Kong?

If it is not, there is a slide switch on the back of most PSs - you must move it all the way to one side so it shows the proper voltage.

Shipping a computer exposes it to possible physical jostling, which can loosen things.
You could try unplugging the case and opening up the computer case and making sure all connections are fully seated on their pins and in their sockets, and the ram and cards all all the way down in their slots.

"After a while the fuse for the room went off."

My brother had one PS that failed simply because of a circuit breaker tripping off in his own home.

Some non North American computers have a fuse in the power cord itself, but if that has blown the computer would not come on at all.

If you can temporarily borrow a used PS from a working computer to try, that will confirm whether the problem is because of the power supply.
