Question about Antec SL400 (761345254007) 400-Watt Power Supply
My computer shut itself down and will not power back up. No problems were indicated before the shutdown and nothing out of the ordinary happened as it shut down. However, nothing will bring it back up. Is there a way I can test the power supply? Wouldn't the probelm either be there or the motherboard? Any advice would be appreciated.
Most commonly it is the power supply. Rarely it is the motherboard when it just stops working with no other signs. You can take a power supply from another computer and test but I bet it is definitely the power supply. You can purchase a power supply tester for around $20 or so but you can get a power supply for not much more than that and test it that way.

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
the leads from your
"((motherboard to your hard drive))" make sure they have a secure connection and
are not faulty or just replace them they could be 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
