This initialization phase occurs right after you turn on your computer and is called the <a href=\"https:\/\/g100.us\/what-is-pc-post-posting\/\">POST (Power-on-self-test)<\/a>.<\/p>\n<p>These LEDs (also called <a href=\"https:\/\/g100.us\/msi-ez-debug-leds-troubleshooting\/\">Debug LEDs<\/a>) can be extremely helpful in narrowing down the root cause of whatever issue you're facing, especially because, in most cases, the Monitor will not function to display more information.<\/p>\n<p><strong>Whenever any of these LEDs stay lit, you\u2019re being informed that something's gone awry.<\/strong><\/p>\n<p>This could indicate several problems ranging from loose connections to hardware incompatibility to defective components that need to be replaced.<\/p>\n<p>This article covers everything you need to know should you ever have to deal with this pesky \u2014 and most debilitating \u2014 issue.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Before_You_Start_Troubleshooting\"><\/span>Before You Start Troubleshooting<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>First things first, you should run a few preliminary tests to make the troubleshooting process a lot easier later on:<\/p>\n<ul>\n<li><strong>Let the LEDs settle<\/strong>. Those indicator LEDs can blink frantically during every boot-up routine. Only if one of the 4 LEDs stays permanently lit for a minute or more do you truly have an issue at hand.<\/li>\n<li>Make sure that all PSU and motherboard cables are firmly in place and that there are no loose connections.<\/li>\n<li>Ensure that all your hardware is compatible. For example, if you\u2019re sporting an AMD Ryzen 5000 series CPU, you won't be able to use it with a B350 motherboard. You can use websites like <a href=\"https:\/\/pcpartpicker.com\/\" target=\"_blank\" rel=\"noopener\">PCPartPicker<\/a> or <a href=\"https:\/\/g100.us\/how-to-check-pc-parts-compatibility\/\">our troubleshooting guides<\/a> to double-check your entire setup.<\/li>\n<li>Remove all USB devices and peripherals that are not vital during the boot-up process.<\/li>\n<li>Reset the BIOS by <a href=\"https:\/\/g100.us\/clear-cmos-motherboard\/\">clearing your CMOS<\/a>, resetting the appropriate jumper, or simply loading the default values within the BIOS itself. Doing so will reset all CPU and RAM settings to their factory defaults.<\/li>\n<li>Remove all RAM modules except the one <a href=\"https:\/\/g100.us\/ram-slots-use\/\">located in the second DIMM slot<\/a> (assuming you have more than one stick of RAM)<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"LED_Indicators_and_What_They_Mean\"><\/span>LED Indicators and What They Mean<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Most motherboards nowadays have <em>four<\/em> LED indicators, all of which have a singular purpose: <strong>to help narrow down issues that happen during the <a href=\"https:\/\/g100.us\/what-is-pc-post-posting\/\">POST (Power-on-self-test) phase<\/a>. <\/strong><\/p>\n<p>Often <em>before<\/em> anything can be displayed on your

Alternatively, you can try slotting your GPU in a different PCIe slot (assuming you don\u2019t have an ITX motherboard) in case the x16 one is damaged. Check to see whether there\u2019s any physical damage on the slot and GPU itself.<\/li>\n<li>Be sure the PCIe socket's back latch has clicked into place when you install the GPU<\/li>\n<li>If nothing seems to work, you can use your <a href=\"https:\/\/g100.us\/best-cpus-with-integrated-graphics\/\">CPU's iGPU<\/a> (if it comes with an integrated graphics chip). Otherwise, you\u2019ll have to replace your graphics card<\/li>\n<li>If possible, try your GPU in a friend's PC to see if it works there.
