Question about Bestec (ATX-250-12E) 250-Watt Power Supply
The diodes that are transforming AC to DC from the secundary winding are fryed... replace them with new ones. the mainproblem is that you must break all the seals of the power supply to do this, so it is wiser to go to a repair center for this if you don't have experience with fixing electronics. Alternatively you can use a Unintreruptible Power Supply ( UPS ) to regulate the current fed in the power supply as power spikes are the main cause of this kind of malfunctions.

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 could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error hope this helps
