I suggest you take the PC to a local computer repair shop. It needs a "hands on" evaluation to find the cause of the problem. I suspect either a motherboard or power supply problem.

Good Luck

But before that,will it be the problem of RAM that causes it unable to boot? I had changed two mobo in 3 years. The technician say its my mobo problem whenever my CPU gets problem. I was wondering how could possible mobo so "weak" if I never touch the internal body of the CPU,hope that that technician do not lie on me though...

So remove the RAM, turn the PC on it should beep - indicating that it can't find any RAM. No beep would indicate a problem with the motherboard.

If you have problems with brown-outs or voltage flux this can damage the MB. Perhaps you need a UPS with a large battery to better protect your PC.

I suggest you buy a different PC and not waste money on one that is defective in design.
