    Laptop freezes after glitchy artifacts appearing on screen


    I have Acer Nitro 5 AN515-52 laptop. It has Core i7 8th Gen 8750H Processor 16GB RAM, 1TB HDD, GeForce GTX Graphics 1050 Ti- 4 GB, 230GB Samsung Nvme SSD.
    It is running Windows 10 22H2, build 19045.2604

    Today I experienced this issue twice. I was working in Cinema4D and my laptop froze all of a sudden with these glitchy artifacts appearing on the screen.














    It was on charging. Then I rebooted my laptop and there was no display. I tried restarting it multiple times by force power down by holding the power button but encountered the same, (more on the power button later). In order to find out whether windows OS got corrupt or some hardware issue, I kept presssing F2 and Del to enter the BIOS. I got blank screen. I realized that the laptop was giving a beep sound on switching off/on the charger during that time. That beep sound always comes whenever I switch on the power from the mains during the bootup of laptop. While usage of laptop normally, that beep sound never came.
    Then, I forced powered it down. I left it switched off for 20 minutes or so, no charging happening during that time. Then it booted normally after me successfully pressing the power button. I ran "chkdsk /f /r c:" in admin cmd prompt after reaching desktop screen. I restarted and then it checked for errors at startup and I noticed that it was fixing errors too during the percentage progress that showed up.

    Everything went fine for an hour after which I put my laptop to hibernate like I do frequently. After 30-40 minutes passed by, I switched it on again. Then I was working on it without having it plugged in. After 45 minutes of working then I faced the same issue of glitchy artifacts on screen and laptop freezing. Both of these troubles happened while doing very basic and light weight 3D modeling in Cinema4D.

    I am using latest Nvidia studio driver version 528.49 . Have my graphics drivers got corrupt? I haven't installed any new software, neither done any major windows update in the last 7-8 days (or more as far as I can recall). At first I thought that it was screen trouble. But now I am unable to figure out.

    I have been also having an issue of pressing the power button for 5-6 seconds to have my laptop startup since I guess July or August 2022. I created a thread here.

    I use the method given here now as a workaround to power on my laptop.
    Acer Nitro 5 black screen? Not turning on? Keyboard not working? I may have found the solution. - Page 2 Acer Community

    Copy pasting the process that I use.
    Apparently, there is a pressurized micro-switch somewhere in the middle of the keyboard, near the letters X C V D F. I pressed down near that spot and push the power button at the same time, and finally the laptop turned on. For safe measure, I put pressure on the spot below the letters of the keyboard. This also works the same way when typing with other keys on the keyboard.



    It was mentioned that "Don't press down too hard, otherwise you may damage the internal hardware.". Have I damaged something internal accidentally?
    I am creating this post right now while typing on the same laptop only.

    I have been also facing this issue on my laptop that remains unresolved.

    Looks like a hardware failure in the GPU and/or associated Vram.
    There should be some indication in the Reliability History.

    To test for that you can disable the Nvidia dGPU in the Device Manager and run using the iGPU.

    I don't know that application, but it may insist on a Nvidia GPU, but you can test with another application.

    Also I would check temperatures whilst it is working hard as elevated temperatures can damage components long term and increase the random failure rate.

    In the reliability history I am only getting this. The improper shutdowns were from my end when the laptop froze and I had to do a force shutdown using the power key. There is no other information.

    I'll do that and check. However, I have been using the same application later but I did not face any such trouble.

    It uses the GPU whenever I am doing rendering. I doesn't use Nvidia GPU when I am doing normal modeling work. Like, making a 3D model of a car by making all its surfaces.

    Yes. Temperatures went above 90 degrees celsius last year when I was rendering animations. Sometimes they went like 95 degrees. Is there any software to check the health of my overall hardware, especially graphics card?

    Yesterday I went to my most trustworthy computer repair shop. He checked and removed two sticks of 8GB RAM and inserted an old 8GB RAM stick (after powering off the laptop of course). The laptop ran fine with no glitches for good 30-40 minutes. I was in disbelief. Then he put my RAM sticks in the slots after I asked him to, and after that the laptop ran fine for 5-10 minutes before glitching and freezing. Then he removed the RAM sticks , and then he inserted his own RAM stick into the slot. The laptop ran fine. I eventually purchased two new RAM sticks of 8GB each from him and he installed into my laptop. My laptop has small section for replacing the RAM and one doesn't have to open the entire case of the laptop. He didn't touch any area of my laptop. He worked only in the area of RAM. I watched the entire repair process in front of me. Ever since the laptop has been running fine.


    It is still getting hard for me to believe that this screen glitch was happening because of faulty RAM.
