So I was trying to stick in a new HDD into my computer, when I misjudged the weight of it, and it smashed into the video card (GeForce 4 Ti4400). At first, the video card worked without a problem, but soon after it began to refuse to boot. I discovered the damage shown here:

So one of the black chips are loose and knocked off its setting, and another piece which from what I can see looks like this:

is missing. I can't find it.

Also, it booted when I put a piece of soldering wire across where the broken chip was supposed to be.

So the question now is, should I solder all of this, without the little chip that is missing? Anything specific I should know? (Besides get a new video card that is)
 
what a shame. you've broken an antique. if it worx, and you cant afford a new card, and your are not worried about what running without the missing component might do to your display/mainboard/cpu, go for it.
 
I would fix it. The one that is missing is a capacitor, you might be able to get by without it, depending on it's purpose (if it's a coupling cap for a signal...it wont work) The value may or may not be critical.

You should post the card details and maybe someone on the forums with the same card can snap a few pics to help you get the right part.
 
Go ahead and try to repair it. If it doesn't work I think this is fates way of telling you to get a new vid card.
 
As long as its not under warranty (Which i doubt it is), than go for it, What do you have to lose?
 
I am going to go with everyone else, and say go for it. But...

The wire you are going to put across it will have a resistance of "x"

And the original circuitry had a resistance of "y". It may cause a few problems in games.

You could buy a new video card, OR buy a used Ti4400 from ebay.

I could only find one at the time of my posting:
Leadtek A250 TD Winfast GeForce4 Ti4400 AGP 4X
Current bid: $ 1.00
Shipping: Probably around $ 13.00

So you could get a new video card for less than 15 bucks.
 
That's a nice hue of purple on the pcb. mine as well try and fix it... nothing to loose really. good luck!
 
If you put a wire across is it will short out. That is marked for a capacitor, which is NOT a physical electrical connection like a wire, a capacitor is a device that stores charge in an electric field between two isolated plates (isolated as in NOT TOUCHING)

Repeat...DO NOT use a wire or solder bridge, you would do better to find any smd mount capacitor and put it in place.
 
I've got an old Ti4600 laying around. If you give me and address to send it, its yours.

Not trying to weired or anything, but I'm never going to use it again.
 
I knocked a few of those off a mainboard (okay, it was more like half a dozen). Mainboard is still working flawlessly today.
 
Looks like you just knocked off a cap, luckily for you soldering an smt cap is fairly simple. More than likely for cost considerations a lot of the same caps were used. Typically when they are making the schematic and assigning reference designators such as the C1203 number, they are assigned at the completion of the schematic and are therefore assigned in order. I would take a look at the caps with the ref designators before and after it and see what their ratings are. Then go onto digikey.com or what not and look for a simliar cap. Looks like a Panasonic cap, perhaps 0603 package, just look for the correct capcatiance ( usually in micro or pico farads) and replace it. Assuming you dont know anyone with the same card that can take a pic for you. On Digikey just look for the cut tape ones, they will be more than the reels, but you dont need 1000 of them :p

Nice to see there are fellow ET's out here
 
hes right just go get the new cap and soldier it the worst u could do is trash it and without the cap it kinda is so go for tha gold man . i would just to say i could if it worked.

Umm, well gee, this guy is nice enough to give you a TI4600. Take his, and be done with the problem.
:p
