I think my HP Pav powersupply is dead. When I plug it in and try to turn it on, nothing happens to the HD and computer except a green light flashes on the back of the power supply. It is a Bestec ATX-250-12Z Rev D1 power supply unit. Does the flashing green light indicate a bad unit or something else?

Try to charged it for 5-6 hours and then try to power on.

sunny,try with a other powersupply if possible.
faulty PSU are often the cause.

step one after checking DC supply voltage to spec
is does the BIOS key works
BIOS must work or the system is dead.
or video out port dead.
is this your first PC failure? experience

see if this dead screen page helps.
your post is not clear at all
start at the power switch and then go into BIOS
can you do that, if not find out why, bad screen>?
bad VGA port? lost DC power, try 2nd known screen
we can see you work and what all you see or saw.
lacking more clear results, and tests.

Open it up again. Take the video card out. Take the Ram out. Unplug the hard drive. Unplug the other drives. Unplug the network card(s). And unplug anything else that is tied to the motherboard. Now plug it all back in snugly.Finally,turn it on. It should be fixed.

On the back of the Power Supply there should be a Green LED, When you power it on if it is flashing, this means that the Power Supply is dead and you need to replace it.

JD, get yourself a cheap battery backup surge protector, I have one and its saved my **** many times, I live in FL and with lightning and power outages its a real system saver.

change the smps.

Find and replace the following caps, Ec18, 19, 20 / 1000uf/16v,
Ec9, 10 / 1000uf/35v, Ec14, 25 / 470uf/35v should resolve the problem. You can get the caps at almost any electronics supply.
This is a common problem in this unit.
Good Luck!
Happy Thanksgiving!
