Tip & How-To about Computers & Internet
So, your computer wont start up? What to do? First disconnect all attached devices, Then we must check to see if there is any Power, Try unit in another power point, if Power Point proved OK, then try & change the Power Lead in, proved OK, then Check the Power Supply, do you see the Fan "Kick"? On the Power Supply AND the CPU Fan inside, proved OK, then Check to see if there is power to the Motherboard? Often there are LED's that show if power is ON. proved OK? We must now remove the Power from each device, DVD, Hard Drive, leaving ONLY the MotherBoard connected. OK, So we are at the MotherBoard, it still won't power up, everything else has been removed... now remove the RAM. power up, Proved OK, if NOT, then the RAM is your problem replace.it power ON, Proved OK, If not then your MotherBoard is Faulty, proved OK, then start attaching devices and re-starting & rebooting each time until you find the one that stops the PSU. That is your problem. At each step if you don't have a, proved OK, then, that last step was your faulty bit, replace or remove.
What we have to do is at each juncture we must test each item in turn, and do a reboot each time connecting & disconnecting to prove the faulty bit.
So say we have tested all from Power Socket to MotherBoard & RAM all test OK, then we start to attach the hard drive & it won't power up, or say it was the DVD, This then is the source of your problems.

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty
One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive
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 a secure connection and are not faulty or just replace them there probably old and faulty
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 electrical extensions or just replace them they are probably old and faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error
hope this helps
