ASUS ROG G750 gpu problem after change thermal paste

Hi everyone. I've problem on my laptop asus g750 jh

problem description :
overheating temp cpu and gpu (90 ~ 91) i change thermal paste for cpu & gpu
and upgrade ram to 32gb 4x8gb g.skill 2133mhz 1.35v and update operating system to win 10
after i do that my laptop work good for two days with very low temp but suddenly my laptop stopped working with black screen and no power.
i disconnect the adapter and remove the battery for 10 minutes and back it again and switch it but i found this screen :





print screen



nots: [ i used ic diamond ].
i back to windows 8 but i have same problem .
i last 4 nvidia driver on win 8 and last driver for win 10 but not solve the problem
warranty will end after 25 days

 

A driver or os reload won't fix your issue, it's definitely hardware related. I would try to reseat the video connector first, make sure you didn't pinch the video cable when you put it back together. Also you can remove the graphics card and clean the pins with an eraser and concentrated isopropyl.

 

Yes time to go back and check out to see if something was not quite put back right.

 

i try many drivers from nvidia and asus site and i try relod os win 8 and 10 and i remove the graphics card and clean the pins but not fix the problem .
someone said to me, goodby to your warranty becasue i changed thermal compound by my self. is that right i lost my warranty or not ??
if i lost my warranty what can i do now ?

 

My guess is gpu problem, i know this cubes. You should try warranty.....

 

try removing the paste again properly with alcohol swab ...make sure u clean it properly ...the small components in the dye too and again apply the paste but of small quantity on the chip and give it a try

 

Yes, last chance. You can set up bios to default or reset.

 

Did you spread your thermal compound? With ICD you want to use the compression method instead of spreading it. Spreading it will cause air pockets.

Technically when you remove the screw on the cpu with the sticker on it that says "warranty void if removed or damaged" then you will probably lose your warranty. Though in certain circumstances it can be overlooked.

 

i try removing the paste with alcohol swab and clean the small components and i used ic diamond with compression on heatsink and i try used antec formula 7 thermal and i have same problem
i try removing bios battery 30 minutes and set default but nothing happen

 

about lost warranty this thing unfair from asus and make me feel remorse for bought asus laptop

 

Without a warranty sticker Asus would be open to constant claims that weren't real warranty issues.

Asus doesn't have very good support (I've dealt with that hell once) but their hardware and designs are among the best out there. I think your best bet at this point is trying to find a local business that can reball your video card or you can buy another video card. You can also try to clean the bga under the chip with some isopropyl and air.

 

connect ur laptop with an external monitor and see if the display is ok there or same like now ! if it is the same thn its ur GPU

 

i did that but they don't show anything no signal

 

i connected my laptop with 32 inch LG smart tv [ by HDMI ] for 2 years .Is it hurt gpu ??

 

thats weird ! it must show display over there if it is showing on ur laptop ! try re installing beta drivers of it or from asus website...first completely uninstall the drivers ...restart..and thn install the new drivers

 

from first time i connect my LG tv on g750 they always show detail after load windows and not show boot screen any way i will try drivers on asus site

 

did u see any box or artifacts in the details on ur LG tv?if no thn ur gpu is ok... its driver issue

 

my tv only show message no signal i test last 2 drivers on asus site but i have the same problem

 

might be a GPU issue thn ...try cleaning the contact pins of the GPU and wash the whole GPU with an alcohol !

 

I don't want to start anything but this obviously isn't a driver issue since the artifacts still exist in the bios.




Please don't give bad advice here, this is how bad information spreads.

Vooo, look into gpu reballing/bga solder rework. If you are in the US you could try L2 computer repair from Brooklyn NY. I have used their service in the past and was more than happy with the final results. There has only been one motherboard they weren't able to repair (G46vw with liquid damage).

Link to their repair service below.

You can also buy another video card if you don't want to go the repair route.

i looked into gpu and i didn't found any damage in solder and electronic parts on gpu pcb - i ask asus support about my problem and they told me
quot replay :
Regarding your inquiry about the heating and booting problem of your device, please contact Metra service center as they may help you with ordering parts of your device from outside the country.
tomorrow i call Metra service and will ask him about if he can fix my gpu or buy new gpu

 

You won't be able to see any damage since the problem is with the solder balls under the gpu.

Here's some reading for you.

Yes sadly a lot of electronic failures only show up with techniques such as x-ray analysis.

 

some friend say to me make reflow to gpu

 

If you have exhausted all other options it can be worth a try, just be aware reflowing if it does fix it tends to not last a hugely long time.

 

That's not always true, reflowing has earned a bad rep because of people cutting corners. The most important step before a reflow is to clean under the chip with air and concentrated isopropyl. The other important step is to make sure the solder below the chip gets to a certain temperature. There are so many people guessing instead of measuring the exact temp.

The machine I used to use when I owned WMC.



I still have a working jtagged xbox that I repaired years ago by reflowing it.

It all depends on the technique.

 

It's going to also depend on the condition of the solder, exactly where the solder is damaged (IE is it betweent he package and chip or between the die and the package). Cleaning the solder that does not have the issue wont help

 

asus egypt support cant help me i will back my laptop to the seller and he will back it to asus usa support that will cost me 600$ dollar (shipping from egypt to canada + shipping form canada to egypt + pay new customs ) i think asus will not pay any thing from that cost

 

thats too much ! u better order a replacement video card of ur laptop from aliexpress !

 

im not sure if the video cars on aliexpress good or damaged

 

dont worry ! buy from a seller whose positive feedback is 95-97 percent
have a look over here http://www.aliexpress.com/wholesale?catId=0&initiative_id=&SearchText=asus+g750+video+card

 

some thing i forget write it after change thermal paste i make stress test by furmark for [40 minutes] i found something strange Frequency gpu up from 771 to 954 mhz . the temp was 77 degrees

 

thats fine 77 degree is ok at full stress

 

Not bad for furmark at all.

 

today i shipping it to the seller

 

what do u mean by shipping it to the seller ? ? ur selling it or u sold it ? or what are u upto?

 

The temps are good so shipping it back would be odd at this point. Was it something you were not happy with?

 

i dont think he ordered any gpu ! he was telling about his old gpu and now the shipping back is about something else because he didnt mention that he bought a new gpu !

 

i purchased my laptop by broker [something like shipping company ]. why broker ? because i cant bought any items direct from usa to egypt and he do the very complex customs clearance.
the broker, described the problem to the seller on ebay and the seller said to him send the laptop to repair it under warranty. [ i can't believe this ]
.i can't bought used gpu because i don't trust it

 

oh lol glad it is under warranty hope u will get it fixed soon best of luck !
