Hello,
The symptoms you describe, such as screen artifacts, issues starting up, and freezing even during a boot from USB stick. Here are a few troubleshooting steps you could try:
Test your memory: Use a memory testing tool like Memtest86 to check for any errors. Your symptoms could be due to faulty RAM.
Perform a hard drive check: Use the built-in Windows CHKDSK utility to check for any issues with your hard drive.
Check your graphics card: Screen artifacts often indicate an issue with the graphics card. If you have an integrated graphics card, try connecting the monitor to a different port or using a different cable. If you have a separate graphics card, try removing it and running the computer without it to see if that resolves the issue.
Reset BIOS/UEFI to default settings: Incorrect BIOS/UEFI settings can cause malfunctioning of your when booting. Power on your computer and during power on, press the key to open BIOS/UEFI settings (usually Del, F2, or F10) and reset to default.
Best Regards,
Hania Lian
