If not, it's really really dead.
There are PSU testers, but for that price I can buy a PSU.
Here's another test -> http://forums.extremeoverclocking.com/showthread.php?t=137886
Page down to the link where thay write about MANUALLY STARTING the PSU.
I have an old PC.
Intel Celeron366,96MB Ram,4.3HDD
It won't start. There's no lights, no sounds. It's like there's no power.
I've opened the case and checked that the fan in the power supply and on the cpu are not running.
I think it's the power supply from I've read in this forum.
How do I check the power supply and is that the only thing I can do?
