sir
my computer not switching on when i press the power butten and not even functioning sir please help in this case please reply me

Hello Sudheer, can you get hold of another PSU? Perhaps borrow one and hook it up to your motherboard and see if it works. If it does I would get a new PSU.

If this is related to your earlier posts concerning your power supply can I just give you a word of caution. If you are turning your PC on and off without giving approximately 10 seconds in between you could end up damaging you motherboard because you need to wait for the charge left on the board to dissipate.

Try switching the PSU, if the motherboard still doesn't power up, a quick and easy way of checking for damage to the board would be to visually inspect the capacitors. There the cylindrical components on your board, there probably black or blue with a silver top. If there is a visible bulge on the silver top ( the top should be flat and level ) then the capacitors have blown.

Be sure to disconnect the power during inspection just to be on the safe side. If there is any damage to the capacitors it doesn't mean you've lost your board, you can take it to an electronics repair shop. Over here in the UK the capacitors only cost about 20 pence ($0.40) each.

Hello Sudheer, the images I have attached shows you a set on capacitors on a board and the obvious damage to some of them.

If there are any that are damaged then refer to my previous message, you will either need to see if it can be repaired or, unfortunately your going to need a new board.:(

plese help me ihave bought the cpu last year only means new one how it can be possible

Hello, I was referring to one of your earlier posts about intermittent power to your motherboard, I just wanted to make sure you weren't turning your power on and off too frequently while you were trying to find the problem as this can cause the motherboard to blow.

Have you tried using a different PSU?

sir could you please tell me how much cost i have tospend for a psu

Hello, first, can you borrow one from somebody for an hour to make sure it is the PSU. Finding problems with computers has a lot to do with process of elimination, if your PC powers up with a different PSU then you know all you have to do is replace the broken one with a new one.

Over here in the UK I can pick one up for about £20.
