Re-pasted the GPU & CPU, my system (PH315-51-50ST) is crashing/hanging when loading games v2

As mentioned in previous thread, re-applied the thermal paste Kryonaut to the CPU and GPU to cool my idle temps. Initially I had issues in booting the laptop, but that was solved by cleaning the fans, replacing some of the thermal pads on the heatsink and ensuring it wasn't fastened too tightly.
The temps for the CPU now are a bit of an improvement from before, at idle its at 40-50°C and when stressing the CPU its at around 75-80°C. However now whenever I try and load any game, the system just freezes up (both video and audio freezes) forcing me to hard restart.

As 'busu3' had asked, I ran the heaven benchmark and the same problem occurred. It had been running for 2-3mins without any problems before the system hang. Before running it I had also done a clean uninstall and install of my nVidia drivers using DDU.

    I would suggest you double check whether you applied the thermal paste properly to the CPU and GPU.
    You need to make sure to properly remove previous thermal paste application and re-apply it... the P-dot method tends to work fine for desktops because they have fairly even heatsinks but for laptops, you may need to spread the thermal paste in a relatively thin layer on both the CPU and GPU dies in order to cover the surface area properly.

    Also, have you checked the VRM chips on the motherboard along with the GPU vRAM chips?
    You may need to re-apply the thermal paste to those too or replace their thermal pads (if they had any), and check if you tightened the screws on the heatsink as much as you could (Keep in mind that laptop heatsinks are not always even, so they sometimes need to be tightened more tightly to ensure proper contact).

    Before replacing the thermal paste, make sure you disconnected the battery from the motherboard just in case and work with anti-static gloves (if you have any)... once you disconnect the battery from  the motherboard, press and hold the power button for 10 seconds to ensure you removed any excess charge.


    Another thing to try if the problem persists is that you could attempt to test whether one of the components might be causing the problem. You could try removing one of the RAM sticks and test to see how the system behaves when one is removed. Repeat the procedure with the other RAM stick... and then alternate the sticks between the RAM slots (sometimes in a desktop, a RAM slot or a RAM stick will be causing massive problems, and I had to remove one thing at a time to test to see what works and what doesn't... it turned out the RAM slot burned out, but the RAM stick was fine, so I just moved the RAM stick into a functioning slot - but your issue, if its caused by RAM could be that one or both of your sticks are causing instabilities hence why I would suggest testing them individually).

    Please perform the following steps and check the CPU usage :
    >>>Power Reset
    Disconnect the charger. Please check for a battery reset PIN hole at the bottom of the device. The reset hole would have a battery symbol next to it. Insert a paperclip into the hole and press for four seconds. Let the computer sit for 5 minutes with no power. Reconnect and monitorthe CPU usage.


    >>>End Task of running programs and Disable Startup program in task manager. This fix can help you quickly end high CPU usage issue when your device becomes extremely slow or even get stuck with running programs:

    Press Ctrl + Alt + Del keys at the same time to bring up Task Manager; 
    Select Task Manager > Check and select programs that are taking high memory and CPU usage > Click End Task to close selected programs or apps. 
    Click on Startup on Task Manager > Select and right-click on unnecessary programs or apps > Select Disable to stop them running from Startup.


    >>>Run DISM command to decrease high CPU usage

    Right-click on Start and select Command Prompt (Admin), sign in with your administrator account;

    Type: DISM.exe /Online /Cleanup-image /Restorehealth and hit Enter;

    Type: DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess and hit Enter;

    Type: sfc /scannow and hit Enter.


    >>>Disable Superfetch and Windows services to fix Windows high CPU usage 

    Press Ctrl + Shift + Esc to open Task Manager;

    Go to Services tab and click Open services;

    Navigate and locate Superfetch, right click on it and select Properties;

    Click Stop to end the Superfetch service and click OK to confirm the change.


    >>>Press Win + R to open Run dialog > Type: msconfig and click OK;

    Check Hide all Microsoft services under Services tab > Uncheck all other remaining services > OK to save all changes;

    Restart Windows > Enable any services individually and reboot PC > Repeat the process till Windows high CPU usage issue gets fixed by then.

    Accept if its Helpful.   B)
