3] Run a RAM health test
Your computer first shows a pixelated screen, then freezes. Hence, this also indicates that the problem may be with your computer RAM. A faulty RAM shows many signs and symptoms. Freezing issues with a pixelated screen are one of these symptoms.
I suggest you run a RAM health test. For this, you can use the Windows built-in Memory Diagnostic Tool or a third-party tool to test your RAM, such as Memtest86+.
If your computer has more than one RAM stick, boot it with one RAM stick at a time and monitor what happens. This will tell you which RAM stick is faulty.
4] Clean your GPU
When does the pixelated screen appear? Does it appear at the time of doing heavy graphics tasks? If so, there may be a hardware fault with your GPU or it may be dirty. Monitor your GPU temperature. High GPU temperature is one of the causes of graphics issues on a Windows computer. If you notice that your GPU is overheating, you need to fix this. Also, clean the GPU. Open your computer case, disconnect the GPU, and clean it carefully.
If your GPU’s thermal paste is worn out, it can overheat, which can impact your computer performance and cause this issue. In this case, I suggest you check the thermal paste while cleaning your GPU. If the thermal paste of your GPU is worn out, you need to replace it.
5] Update the BIOS
You can also check for the BIOS update and install it if one is available. However, before updating the BIOS, you need to check the BIOS version via the System Information tool. You can download the latest BIOS update from your computer manufacturer’s official website.
While installing the BIOS update, make sure that your computer gets a continuous power supply because the power supply interruption during the BIOS update installation can break your motherboard. Laptop users are recommended to connect a charger, even if their laptop is completely charged.
8] Your Graphics card driver might be faulty
If none of the solutions work for you, your Graphics card driver may be faulty. Contact a professional computer repair technician for further assistance.
I hope this helps you fix your problem.
