In order to resolve this issue and eliminate unwanted application crashes, use the methods explained below.<\/p><p><strong>Pre-activity<\/strong><\/p><p>Before moving on to the elaborate methods to address the error message, check all the hardware components like RAM, HDD\/SSD, PSU, GPU, and more. Also, check for damaged cables and loose connections.<\/p><p>Simply power off your computer and check the RAM sticks for damaged pins or whether they are correctly seated. Do the same for the GPU, CPU cooler, and other components.<\/p><p>Once you are done with the above activity, move on to methods to fix the EXCEPTION ILLEGAL INSTRUCTION error message on your Windows 11 PC.<\/p><h3 class=\"wp-block-heading\" id=\"h-method-1-run-memtest86\">Method 1: Run Memtest86<\/h3><p>The EXCEPTION_ILLEGAL_INSTRUCTION error could be generated due to a faulty or non-working RAM module. To check if the error at hand is really memory-driven, you can test the RAM modules using MemTest86 &ndash; a freeware to check &amp; test the RAM modules for any errors. To use this tool &ndash;<\/p><ul class=\"wp-block-list\">\n<li>Download <a href=\"https:\/\/www.memtest86.com\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">MemTest86<\/a> from its official website.<\/li>\n\n\n\n<li>Follow the <a href=\"https:\/\/www.memtest86.com\/downloads\/MemTest86_User_Guide_UEFI.pdf\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">instructions<\/a> to create a media creation tool for launching MemTest86.<\/li>\n\n\n\n<li>Launch Memtest86 by following the instructions given <a href=\"https:\/\/www.memtest86.com\/downloads\/MemTest86_User_Guide_UEFI.pdf\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">here<\/a>.<\/li>\n<\/ul><p>Memtest86 will scan the RAM modules for any malfunctions or errors and display them on the screen. Take appropriate steps to fix the indicated errors.<\/p><h3 class=\"wp-block-heading\" id=\"h-method-2-boot-your-computer-in-safe-mode\">Method 2: Boot Your Computer in Safe Mode<\/h3><p>Booting Windows 11 into safe mode can help you circle out the underlying issue causing the EXCEPTION_ILLEGAL_INSTRUCTION error on your computer. When you boot your computer in safe mode, the computer runs only a minimal and required set of processes. No third-party applications are initiated.<\/p><p>By doing this, you can test if a system file or process is going haywire, causing the EXCEPTION_ILLEGAL_INSTRUCTION error message to pop up on your screen. To restart the computer into safe mode &ndash;<\/p><ul class=\"wp-block-list\">\n<li>Press <strong>WINDOWS + R<\/strong>, type <strong>msconfig<\/strong> and hit <strong>Enter<\/strong>.<\/li>\n\n\n\n<li>Click on the <strong>Boot<\/strong> tab in the <strong>System Configuration<\/strong> window.<\/li>\n\n\n\n<li>Under the <strong>Boot options<\/strong> section, select <strong>Safe Boot<\/strong> and ensure that the marking under it is at <strong>Minimal<\/strong>.<\/li>\n\n\n\n<li>Click on <strong>Apply<\/strong> and then <strong>OK<\/strong> to boot Windows 11 in safe mode.<\/li>\n<\/ul><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"571\" height=\"385\" src=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/12\/mark-boot-safe-minimal.jpg\" alt=\"boot computer in safe mode to fix the exception illegal instruction error message\" class=\"wp-image-156356 apply-gradient-on-post-images\" srcset=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/12\/mark-boot-safe-minimal.jpg 571w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/12\/mark-boot-safe-minimal-300x202.jpg 300w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2023\/12\/mark-boot-safe-minimal-150x101.jpg 150w\" sizes=\"auto, (max-width: 571px) 100vw, 571px\" \/><\/figure>\n<\/div><p>Once inside, check, if you are getting the <strong>EXCEPTION_ILLEGAL_INSTRUCTION<\/strong> error message.<\/p><p>While in Safe mode, you can also run the <strong>System File Checker<\/strong> to resolve any system files-related issues that might be causing the EXCEPTION_ILLEGAL_INSTRUCTION error on your computer.
