I have a really expensive card that arrived damaged to me. It has a resistor broken off on the back. (I think that is what it is, not a electronics expert) I need to know the model number for this resistor because, I think I can solder it back on. I don't have a lot of experience soldering things, but I have fixed a couple of things before. I have seen similar looking resistors on a back of older LGA775 cpu's (mostly Pentium 4's). Are these the same? Can I take one off an old cpu? Also, what are the chances that this board is already fried if someone used it after resistor broke off? (this ruler measures centimeters) Another question: On the front of the board, there is a coil component, that that has a 4R7 mark on the top. Like that: The problem is that the top cap with "4R7" mark is damaged - a part of it is missing. I was wondering if it will affect its' performance. EDIT: I also don't have any soldering equipment on hand and not sure what best to buy for this kind of precision work. Any advice would be appreciated.
