Expert: Mike - 11/5/2009

Question
Dear Sir, i've Dell DHS Desktop,on turning ON, processor fan's spead increases just like jet Fan. Monitor and CPU light goes orange. Don't works even it keep switched on except high spead Fan. I have cleaned every part of motherboad even checked unpluging CD-Rom drive, HDD, Flopy drive, removing CMOS battery but all in vain. Please help to resolve this issue. Thanks.

Answer
The fact that your monitor light stays orange means that it is not receiving any video signal from the computer.
Unfortunately my guess is that your motherboard, or your processor, has completely failed. In which case there is really much you can do except replace the computer.
