Can anyone help me. My Mobo is as dead if I
switch it off/shutdown for long time. To turn
it on (to be able to boot) I would have to
power it on and off at least 10 times
continually.

Have you eliminated your power supply as a cause? If the problem really is your motherboard and it started to work, would you trust it? Probably time to replace it.

1). Power supply.

2). Processor (incl, heatsink and fan)

3). Memory chip(s).

Please post back if you have any more problems or questions.
If this info is useful, please give a thumbs up. Thanks

This does sound like one of the behaviors for bad filter capacitors.

If you have eliminated the power supply and other hardware, it is time to inspect the motherboard.

Look at the filter capacitors (round silver topped parts) near the power connector and CPU socket. If any of them have rounded over tops, or a liquid leaking out the bottom, then failed capacitors is the problem.

Unless you have the correct soldering tools, and are skilled at removing components from multi-layer circuit boards, this is not a do it yourself task.

Further, if one cap shows the physical signs, you should go ahead and replace them all.

It is usually much easier and cheaper to find a new motherboard.
