Hello,

Following my exam i noticed that there is not thermal pad on the graphical chip...but as i use the old heatsink cooling module there is not place for adding thermal pad in order of cooling this chip. 

perhaps i had to order another cooling module

The GPU needs to be cooled. If there is an HP part number on the motherboard you can look it up here

Usually there is a "where used" under the lookup and one can search the "where used" to find a cooler that fits both the CPU and GPU.

Do you have a link for the AliExpress part that shows an image?  Is there an HP part on motherboard?

If the motherboard has a dedicated GPU it is probably better than the old motherboard and it might be worth the effort to find the correct cooling hardware.

Hello, thank you for your contributions...

Actually that was the overheating of the gpu (here : amd vga graphic chip) which caused the shutdown.

i ordered a new heatsink with a radiator for cooling the graphic chip. I put thermal pad on the radiator and now the system works for more than 30 minutes.

however I have a small problem. Normally to fix the graphics chip radiator to the motherboard there are 2 tabs with 2 screws. But on my motherboard there is nothing to fix these 2 screws. there is no support for screwing.

What is the name of the support which should normally exist on the rear side of the motherboard and which receives the nuts where the radiator screws are attached? if i had the name and the references of this device i could order it and firmly attach the radiator on the motherboard. With a little luck i am going to try to send you with this post the photos of the rear side of the motherboard and of the new heatsink.

Waiting for your answers.

Usually there is a plate on the backside of the motherboard with female screw towers that come up through the holes in the motherboard and then you have male screws going through the heatsink that screw into those female screw towers. On desktop motherboards you sometimes get some single female screw towers that have a rectangular base bigger than the hole so you can use them to receive screws and hold things down.

Thank you for your answer...

i absolutely agree with you, but as you can see on the photos that i sent in my previous post there is no plate (rear the graphic chip) on the backside of the motherboard, it is missing...(it has been taken off or taken apart).

If somebody could help me to find links on internet where i could find and order such a plate with screw towers i will be very pleased?

the screws of the radiator are rather small; so if somebody could send me the references for the screws towers to attach the previous ones it will be a great thing...

Thank you in advance for your help (the reference of the motherboard is : P/N :01013y000-600-g rc8f32004ah1 for a hp g72 pc.)
