I have ZOTAC GeForce GTX 1080 Ti Mini graphics card. The card has worked well so far but a few days ago the card became unstable. I noticed that transistor Q586 had come off the card and I can't find it anywhere.
When I asked zotac they refused to say what component this is. Could someone with this same card look at which transistor this is?

Are you certain there was a transistor on Q586?

It's not the only 'empty' PCB slot (not suggesting three have come off; rather, there wasn't a transistor soldered there in the first place).

First of all components do not come off, they only come off due to bad mistreatment. ..Second you can tell if you ripped a component off by traces of solder left-over on the pad.

Q586 is the only one that looks suspicious to me, but an easy way to check is to Google your card & look at online images, but saying this if the card was working & you have not touch it, then something else has gone wrong, either software or hardware. Personally I would start at the software side first, even if I have to do a 100% clean install of windows & drivers. ..You never know, It could just be corrupt files.

this one?

nope, looks like normal. or just miss something

best pic i found is on hardwareluxx and it seems to me op is right about that one is missing:

if zotac does not answer then ya could maybe ask Bullzoid from actuallyharwareoverclocking or on hwbot.org in the voltmod section

Yeah, can confirm, Kitguru has a PCB shot. Q586 is missing from OP's card.

Edit: @micropage7, in your 2nd pic, Q586. Near the screw. Def missing from OP.

Chances of a component falling off are slim to none, maybe you handled it badly, or it simply wasn't there in the first place. Instability happening all of the sudden can't be result of a transistor missing, that may or may have not have been there. I would do what @delshay suggested. Before fresh Windows install, I would suggest using DDU in safe mode, and fresh driver install. Did you buy the GPU used? Did you clean the GPU using highly compressed air recently? As far as I can see that GPU has a backplate, but it could be possible to blow a component off with highly compressed air.

Yes, correct that part is missing. Normally you will find knock off parts by end users near the screws holes., ie card put back together in a rush & not being careful.

If OP has the skill, he can salvage a replacement part from other dead devices. It won't be the exact same part but a drop-in replacement that function just the same. Less than two mins fix for those who know what they doing.

That's normal, no part here, but you can add-in the extra capacitor if the end user wishes to do so.

The previous owner had had a water cooler attached to this card and there were a lot of traces of use on the card and probably when replacing the cooler something has hit that transistor.

I next tried to remove the drivers and install new ones with no effect.

All the components look otherwise intact but only that Q586 is missing. I also tried to look for pictures of this card online and clearly this has detached that component. This component is close to other solder spots but only here has clearly been the component attached.

That kitguru image also shows this component but the resolution just isn’t quite enough to tell what part this is.
 
It's a transistor. How many functions do you think a three legged transistor can do. The card will not function correctly without it.
 
Impress by what you are asking, so you know how to fix it if you had the exact replacement part. There should be high resolution breakdown online somewhere.

Can you not work it out by putting a DMM to those pads? ..CAREFULL! Do not power-up the card without GPU heatsink.

Yes, if only I knew the part number.
I've been looking and asking about part / image but not big enough for the resolution of the image is not found.

DMM doesn't really help. An electrical diagram would help but you can't get it anywhere.

I think this transistor is of some npn type but I'm not sure...
 
hello everyone maybe anyone could help me i have blown IC (U15) named on the board and i cant read its number. have any still has a card like this that could help ? :)

Part number is uP1666Q.

Can you read your card Q586 part number??
