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.

sir
you have asked me to check the capaciters on the mother board but i haven't find any blue or black marks then how can i identify the problem please help me

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.:(

sir
i have'nt find any such capaciters in my mother board there are no such capisiters are blown or swollen.(located in the images you sent)
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?

Martin

sir
i have only one pc from which i am typing this message can use the psu of this p2 cpu

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.

Martin

Sir
When I Tried To Remove The Big Port From The Psu In To Th Motherboard It's Toostiff To Remove Please Tell Me What Are The Steps I Have To Follow To Remove The Wires

Hello Sudheer, hold on I'll send you a post with a few images to help you.

Martin

okay sir i will wait

Removing your PSU

Note: Before starting, check wether your PC is using the ATX or ATX12 power supply, as the main connector to the board will be either 20pin or 24pin. You may also want to use some adequate anti-static protection such as an anti-static wristband. Remember to be careful!!

Ok, before you remove anything get a pen and a piece of paper and take note of all of your power connectors and where they are connected to.

-Take out the plug going from your mains power supply into the back of the PSU.

-Remove all of the 4-pin molex connectors from all of your drives (CDROM, DVD ROM, Hard drive, Floppy drive (this is a 4-pin mini-molex connector)).

-(refer to ATX connector.jpg). To remove the 20-pin main power supply connector you need to pinch the small tab circled, and it will come out with a little bit of a pull. If you have the small 12v 4-pin molex connected to the board then you need to do the same with this one as well (12V.jpg).

-Check for any power supply from your fan onto the motherboard and remove it. Along with any additional connections such as graphics card power supply.

-If you are just going to use your other PSU to test the motherboard it won't be necessary for you to completely remove the PSU from your PC tower. Although if you feel that this is necessary, then you should find about four screws on the back of your tower which are holding the PSU in. Carefully undo the screws and remove the PSU.

-Take your other PSU and put it in the space where you have just taken your old PSU from and replace the screws.

-Refer to the notes you took earlier and connect all the connectors to the appropriate slots either on the board or to the drives, make sure you are connecting them the right way round to avoid any damage.

-Check again to make sure everything is where it should be (especially the power for the fan because if you forget this one it will take about 60 seconds before your processor blows!, then connect the plug from the mains into the back of the PSU and turn on your PC.

P.S. If the PSU you are using to test your board isn't very powerful and it still doesn't seem to power up then just leave all the connections on the board and disconnect all your other drives except for the hard drive.

sir
can i use the my p2 psu for the test

If you have got an AT connector on your P2 PSU then unfortunately it won't fit. If however you have the ATX connector you could use it, but the P2 PSU probably hasn't got the additional 12V connector for your P4 motherboard.
