My son-in-law's computer, a Compaq Presario 4550, has problems with a
himem.sys alert on reboot and the system freezes. I suspect that the power
supply is the problem and I want to test the lead that is used by the power
supply for the hard drive. I have previously replaced the power supply fan
and used a Y power cable to run both the fan and another device because the
mother board connection for the fan was broken.

I have a volt meter. If I put one probe of the volt meter into the socket
hole that goes to a red wire, and the other probe into the socket hole that
goes to the adjacent black wire (and the same for the yellow wire and the
adjacent black wire) will this give me the voltage readings that I want?

I don't want to short circuit the power supply (which may be on its last
legs), but I do want to test it before replacing it. Is this the correct
procedure?

If anyone has an "Oh my god!" reaction to what I propose to do, please let
me know.

Thanks
