Old desktop no power

[Elliah]

i have this 4 year old desktop pc that i want to get up and running again...its previous owner dropped it off with me a couple days ago...i cannot get it to power on (no fans no lights no nothing)...but the power to the monitor is working ok...what could be the problem?

 

[kimsland]

I'd say Power Supply or Ram

 

[Elliah]

so how do i test to see what actually is causing the problem?

You need to swap parts in and out, until you work out which one is faulty.

Actually this is a good start: BenchTesting

first check is to test the PSU with a tester tool and multi-meter.

how come there is power to the monitor?

No, the "PowerSupplyUnit" (PSU) inside the Desktop computer

 

[Elliah]

this is an old computer where the power supply to the monitor comes from the psu in the desktop...

 

[kimsland]

The monitor does not use the entire PowerSupply (circuitry)

 

[Tedster]

power to the monitor and/or the mobo does not guarantee you are getting sufficient power or correct voltage off the PSU. The only way to be sure is to test it with proper tools. Most monitors do not run off of PSU power. In fact, I know of none, but there could be some out there.
