I have a power supply which gets down after 24 hours working.
I replaced the output capacitors and its Fan (because it did not work),
but I still have the problem and power supply turns off after about 24 hours. it should be noted that, the 5V-vsb is still alive when the power supply is dead.
I got confused, I would be appreciate it if you suggest me a way.

Hi,

What do you expect us to do?

Looking in a crystal ball to find out what type of power supply it is?
Or do you think a quick prayer could help?
