GeForce 8800 Uh Oh!

A student gave me an old GeForce 8800 I think its a GT or GTS
anyways, I took it out of the bag and a little solder joint rolled out with it.
it was a very tiny cube of solder. So I started looking around on the card and found that it connected the joints to a capacitor (I think) on the other side.
Looks like the joint was holding the capacitors two solder joints. So my questions is....
Will this be a problem?
Are these 100% necessary?
Should I try the card or am I going to destroy it?
Should I give it to Wonderbread?

Are you sure it is just solder?

I am no electronics expert, but normally you would see lots of tiny silver cubes on the back of the card. I think these are transistors.

It would help to carefully examine these "cubes of mystery" under a magnifier. Probably better not to install the Vidcard before seeing wth these things are.

Hey Booman, here's some pics of the 8800GTS which was the card I was using before I replaced it with the GTX 470 SC.

It would be very helpful if you know how to successfully solder Surface Mount Components at this point. Sorry, I don't know puzzactly what kind of gizmo it is, but don't plug the Vidcard in until you've re-soldered the traitorous little mutha.

exactly, that is what I'm afraid of too...
I don't even know which way to solder it on. I'm sure that I can look at the other 50+ transistors and align it the same way, but I don't even have a soldering iron small enough....
So I'm giving it to Wonderbread and we'll see if he can manage to get it working.

I've received the card from booman. When I can get the right sized soldering tip I'm going to give it a shot and put the resistor back on. I'll take some pics just before I do it to make sure I will be doing it the right way.

stay tuned.

Its not what I thought it was booman.

I had a little bit of time to troubleshoot to find the root cause of the problem because what I thought was strange was that the picture on my second monitor was perfect.

So I plugged my Wife's laptop into my main screen and still the lines showed so I knew then that the card wasnt the issue. I unplugged everything from the monitor and let it sit for 5 min, plugged it all back in and everything is good again.

Now my question is, and I hope Gizmo sees this cause I have a feeling he will be able to give me an answer. Are the lines shown in the picture a sign of caps going bad in my monitor? I'll have had it for a year in January. I haven't yet looked up too see if there are know issues yet.

Cool and not Cool. I'm glad the 8800 is still working, but it sucks when your monitor is crapping out.
I havn't seen artifacts like that. If its capacitors, then you may have some more soldering to do.
I'm assuming its an LCD?

So it's an intermittent prob with the monitor? Or did the unplug/replug maneuver fix those uncute lines? Hope so!

unplug/replug + power cycle the monitor seems to have remedied the issue for now, but I'm afraid the issue will come back when I least expect it.

that is pretty strange. You can also discharge the capacitors by unplugging the monitor power and then press the power button.

My previous monitor suffered from some kind of glitches.

It's always possible these things are bugs in the panel's firmware.
