I have a problem with one of my office PCís. When I press the button to turn on the PC it briefly kicks into life then immediately switches off. Its that brief that there is no time for any text to appear on screen. As soon as it switches off it instantly tries to start again on its own, from then on itís a continuous cycle.

Then on the odd occasion is boots up as normal and everything is ok for varying lenghts of time, then it cuts out and starts the cycle again. Weird!!

I suspect its some sort of hardware fault but not having much experience with this sort of thing Iím stumped. :whistling:

Can anyone shed any light?? :blink:

Hello there.

From previous experience I know the Dimension 2400 does this when the heatsink is clogged and is not seated properly. Although this may not be related to the issue, I advise that you clean out the heatsink and and other fans you may have added yourself[bearing in mind the stock 2400 doesn't have any other fans]. Have you checked to see if the system is still in warranty? You can find this information on the Dell website, or if further assistance is required, their online technical support chat is excellent. However, if the system is out of manufacturers warranty and the couriers warranty(usually the courier gives a longer warranty period than Dell itself for some bizarre reason) the Dell online chat operators may refuse to help as it is "no longer their problem" - but I personally have never experienced this but know others that have. Good luck, and if you need any more help - you know where to find us!
