Hi All



Major problem here. Just want to know if anyone has any idea what this might be.



The computer was asleep at the time the power went off. Now, if I hit the startup button, the light comes on as I hold the button down, but that's it, no boot up, nothing.



Is this a problem with the power supply? Has something been fried?



Any help much appreciated.

    Try this: disconnect the power cable from your computer. Then wait a few minutes and open the case. Somewhere near the small battery socket on the mainboard, there should be a little switch (looks like a round button, 2 mm in diameter, = CUDA switch). Press it for about one second, not longer! Then close the case, reconnect the power cable and try to start the computer.



    Does that help?

    My friend - if you ever find yourself in London NW5, please feel free to email me and claim your free pint of beer.



    I had visions of buying new power supply, internal hard drive caddys etc ect...



    Many thanks
