Question about Compaq Presario 5000 PC Desktop
This computer wouldn't turn on. I thought it may be the power supply, so I used another one and yes, it was the power supply. However, when I tried the new PSU, I had all other peripherals disconnected except for the motherboard and video card. After the mother board loaded up fine, I thought that the problem was solved. So, I went ahead and put everything back together, but when I went to turn the thing on, it did just like before!
I checked voltage at all the connectors and both PSUs are definitely broken now. So, I've concluded that there must be a short in one of the components that I had disconnected. They are:
Modem, ethernet card, floppy drive. 2 HDD, and a DVD-RW.
I'm guessing that its one of the drives that require power, but I guess it could be one of the PCI cards too. I thought I could check the power connectors of the drives to see if they were shorted, but I don't know what Ohm reading to expect. So, I won't know if the reading is normal or not. I don't want to keep burning up PSUs just to find the short.
Does anyone know the normal resistance readings for floppy, hard disk, & optical drives on the power terminals?
