1.) That's surface mount. So it will likely have no stripes
2.) You probably won't be able to find a schematic BUT if you can get another member of OCN with a 9800GX2 to take a mufti-meter to that same resistor, they can measure what the resistance is suppose to be! yay!
3.) Do you have a pair of caliper that measure is metric? These are useful to find the package size.
Here are standard package sizes. http://www.interfacebus.com/resistor_table.html

would it be easier to throw away the broken PCB and just buy a dead 9800 and use the PCB to fix mine? because that sounds like alot of work

See my edit to my last post. "Both PCB's are the same? Then your in luck. Just measure the still attached resistor with a multimeter. You can get a multimeter at your local Radio Shack for about $10. Also you can borrow one from just about anyone who has worked with electronics."

I have done PCB design and assembly. Working with surface mount equipment is miserable. You will spend 2 hours trying to figure out how to replace a 1 penny resistor....assuming you have all the right equipment.

Measuring resistance of a resistor while in circuit may give you incorrect results. To get a proper reading you have to remove the resistor from the other card which might not be worth the risk.

This, the resistor would need to be removed for accurate measurement. I admit, my "hands on" expertise with smd is low but, Is it just me or does the reference pic for the missing component look like a capacitor not a resistor?

Does your camera have a macro mode? something like a flower icon on some point n shoots.

they are pretty darn close only difference is one has the PCI Express connector the the other does not

to the TS: that's not a resistor but a capacitor.

so it would be much easier to find the correct type then?
