Big Resistor Burn On PCP Help

[XMA]

Well I have a old IBM power supply I need to fix and well first it did not work so I had checked for bad caps and so I did found 2 bad ones and has replaced them and still the power supply does not work now I check other places on the 2 board massive power supply and on the 2 board connector board there is a burn mark from a resistor and another component, the resistor was so hot that it burned of 2 of its color codes and I don't know if it's normal but another component is realy dark but not black and when I look the part up on the internet it looks totally different, like internet blue and mine dark and I was need in help with, if the PCB is that burnt is the resistor dead and the other component and is there a way to test a resistor out without a multi meter and I am new and it's my first post

You will need to at least test the reisistor with an ohm meter (dmm or whatever has an ohms function!) to try and see if it has a sensible value or is open circuit. Being a power resistor I would say its value will be on the lower side. Do you know someone who has a dmm ?, who can check for you. (Im guessing you don't have one!). Also should test the diode is not shorted as well.
 It could be the resistor just runs on the hot side and after all these years of running this 'old supply' it has slowly cooked itself and its surrounds.
The ceramic disk capacitor is most likely okay (cannot read its value but the volt rating is 1kV). Diode looks to be a standard 1n4007.
Maybe you should think of getting a DMM if you intend to tinker with electronic things, get a reasonable one and you will not regret it. (note there are PLENTY of threads on here asking about "which multimeter shouls I get".
