The mother board is 4 years old, and development a fault which has got progressively worse over a matter of 2/3 days. On power up the power light flashes instead of staying on, and there is no display, no bios display etc. I have removed everything apart from the memory and grphis card both of which I have changed. I have wiggle all connectors, but am coming to the conclusion it's time for something new.
Any advice would be appreciated.
Thank you PaulC

A> Check you Power all connection proper connected. B> Check you SMPS power proper working or not. C> If direct display not coming then sec option is external display card connect in mother board and check display come or not. if display come then you internal display cheap damage. If both option used or display no then you mother board problem. D> Check you RAM, section if RAM problem then display no. E> And finally one time mother board bios batter disconnect and few sec wait and re-connect bios batter. Remember batter disconnect before all power cut. Thanks...

find out the price and then compare... but in my experience... its cheaper to get a new mother board with the chip and then just install it... in the end... all you are really concerned about is the hard drive... becuase thats where your data is...

remove ur power supply socket from the mother board short the pin green and black in the connector if the smps start no problen with the power supply then the problems lies with ur mother board wiring or fault in your mother board if your mother board has secondry power fix it correctly to mother board sock et with has 4 pin if its not working cousult a chiplel engineer the fault lies in the power supply of the motherboard
