Thank you for for the reply, I did'nt add any graphic cards or drives, i had only one hard drive sata 160 gb, and one cd rom and 512 ram nothing else. in the past month i had replace the psu from 400w to 500w atx psu beacuase i think i need to increase the power and it work for a month only and down again. i also try to disconnect all the supply to the hard drive and cd rom and turn the computer and still nothing, i tried to remove all parts including cpu and battery and put back all together but same as usaull, the cpu fan turns a split second only and stop.
Sorry, but looks like the main board is dead (or the main CPU)
The minimum is to have the CPU and RAM installed, so the bios can be accessed.
test all power and data leads that attach to your hard drive the leads from your
((motherboard to your hard drive)) Sata make sure they have dust free secure connections and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd have secure connections and are not faulty
even something as small as a faulty fan lead can cause you problems a computer needs all of the power and data to travel through every working device and to
have an end for a computer to be able work properly
make sure your graphics card is securely seated with no dust
if you remove the graphics card to clean the socket replace it
restart the computer the found new hardware wizard should activate
hope this helps
is it only the screen and not the cd rom that does not work
test all leads that attach to your hard drive including electrical extensions,IDE,SATA
the leads from your ((motherboard to your hard drive)) make sure they have secure dust free connections and are not faulty or just replace them they might be faulty
if its a 40 pin flat ribbon type it will be the first to fail
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electical extensions
even something as small as an electrical fan and its lead can cause you problems
computers need all electrical power and data to continue through every working device and to have an end so any faulty leads will end up with a computer error
make sure your graphics card is securely seated with no dust built up or in the socket
if you remove your graphics check the socket to make sure its dust free
restart your computer then reinstall it this should activate found new hardware wizard
if you need more help with this or if i have missed the problem post a reply
hope this helps
