Hi, I just replace my 1080 ti hybrid cooler with the accelero xtreme 3 cooler . Afterwards I have black screen when I turn on the PC. I remove all the components of the accelero xtreme 3 cooler and put back the hybrid kit. When I talk to the customer support they said I could still send it to them but a RMA is highly unlikely due to the fact that I used thermal adhesive. Is it possible for thermal adhesive to damage pcb ?

Can't post pics because the file are too big? About 4mb per pic

It's possible you may have damaged or knocked off a small SMD near the GPU. If you did that, then they probably won't cover the repair via RMA. Not sure why you used thermal adhesive instead of just a thermal compound. The mounting hardware it came with should have been more than enough to secure the cooler to the card. 

The thermal adhesive was used to put on the alluminum heatsink for vram and power. The adhesive that come with the kit is not electric conducive .

Are you sure it was an adhesive and not just regular TIM?

Hard to tell but he might have been talking about those heatsinks you can get with the adhesive on them? The memory modules appear to have round spots versus the typical full flat coverage of OEM thermal pads.

I used regular thermal paste for the core, and the adhesive for the vram and power. It harden after an hour to keep the heatsink in place.

Maybe a fine or extra fine scotch-brite pad. I doubt it hurt the parts, but may polish them too shinny.
Do you have an old board and adhesive to test?
A fine scotchpad should not scratch the parts, but may take off and writing if gone too far.
Worth testing if no other options come to mind.

I got this from google.   Acetone may very well work.  Then use 90% alcohol after that.
Fine sandpaper 2-3000 grit.  But again it may polish it and make it shine and remove any markings if gone too far.
 
How to Remove Hard Glue
Make sure the glue is completely dry and hard. Dip a cotton swab into acetone-based nail polish remover. ...Scrub the glue vigorously with a toothbrush until the glue flakes off. ...Rub the glue gently with very fine sand paper if the gluestill remains. ...Rub the laundry detergent into the glue with your finger

The simple act of pulling the heatsinks off after gluing them on could have damaged the card. Those memory chips are attached by BGA soldering technique and pulling on the glued heatsinks could have broken some of the BGA solder points. Thermal adhesive is usually a one-time permanent decision.

Yes this is the current condition of the card and if you know how to remove the substance without scratching the pcb I would be appreciated it if you could tell me how.

 
Gah,... Okay, now that I have looked at a few more of the images, 50" 4K is dandy for aging eyes, it appears you have damaged some of the ICs. I cannot tell if functionally you have damage, but you can see damage were the adhesive has removed some of the IC packaging material. If it is only surface damage, it will still operate but, that's still a lot of mechanical stress on solder. The uneven surface might cause some issues with cooling the ICs. There's epoxies you can use to seal and even out the surface of the IC. I don't know what your skill level is but most of the surface adhesive left on the tops of the IC's could be scraped off with an exacto knife and magnifying glass. You really don't care about the bits left on the PCB or small parts that don't contact the heatsink or need cooling. You just want a relatively flat surface for the thermal pads to sit on. It does not have to be perfect.

Quick question... is that copper showing through the PCB? It shows in multiple pictures:

Yes those are pry marks on the PCB...probably fortunate those were round adhesive pads...
 

i think so @the_Scarlet_one would that considered as damage to the PCB? 

ahh thank you @the_Scarlet_one for clarifying that, and thanks to everyone taking your time out to help me.
