![]() An improperly installed CPU can also cause this diode to blink ensure that your processor and all necessary power cables from the PSU(4-pin, 8-pin!) are properly connected.Here’s how to update your BIOS even if your CPU is currently incompatible (without a CPU) You may need to update your BIOS if your CPU was manufactured later than your motherboard.Check your motherboard’s QVL (Qualified Vendor List) to make sure the CPU you’re running is compatible.This diode will indicate any kind of issue related to your CPU, including compatibility issues, outdated BIOS firmware, and more. Check your Motherboard’s spec sheet and manual NVMe isn’t supported by all M.2 slots, chipsets and motherboards) you’re trying to use. For M.2 SSDs: Be sure your motherboard in fact supports the type of M.2 Drive and interface protocol (e.g.For SATA HDDs/SSDs: Be sure both the Data and Power Cables are plugged in and that the SATA Port you’re using isn’t disabled because of bandwidth sharing (try a different SATA port).If it’s corrupted, you can try reinstalling your operating system of choice otherwise, you’ll need to replace it altogether and embark on this process from scratch If the issue persists, either your boot drive is corrupted or is flat-out dead.If you still can’t get the system to boot, unplug all storage drives except the boot drive and then try again.If your BIOS doesn’t detect your SSD, be sure to step through our guide here.Otherwise, ensure the boot drive is properly connected and is set as the primary boot drive within your BIOS.If you’ve just assembled your PC, this diode may blink because there’s still no operating system installed.If this particular diode starts blinking, your HDD/SSD is the culprit. The BOOT LED lights up to show the status of your main storage device - the one on which your operating system is installed. Often before anything can be displayed on your monitor. Most motherboards nowadays have four LED indicators, all of which have a singular purpose: to help narrow down issues that happen during the POST (Power-on-self-test) phase. Remove all RAM modules except the one located in the second DIMM slot (assuming you have more than one stick of RAM).Doing so will reset all CPU and RAM settings to their factory defaults. Reset the BIOS by clearing your CMOS, resetting the appropriate jumper, or simply loading the default values within the BIOS itself.Remove all USB devices and peripherals that are not vital during the boot-up process.You can use websites like PCPartPicker or our troubleshooting guides to double-check your entire setup. For example, if you’re sporting an AMD Ryzen 5000 series CPU, you won’t be able to use it with a B350 motherboard. Ensure that all your hardware is compatible.Make sure that all PSU and motherboard cables are firmly in place and that there are no loose connections.Only if one of the 4 LEDs stays permanently lit for a minute or more do you truly have an issue at hand. Those indicator LEDs can blink frantically during every boot-up routine. Before You Start Troubleshootingįirst things first, you should run a few preliminary tests to make the troubleshooting process a lot easier later on: This article covers everything you need to know should you ever have to deal with this pesky - and most debilitating - issue. This could indicate several problems ranging from loose connections to hardware incompatibility to defective components that need to be replaced. Whenever any of these LEDs stay lit, you’re being informed that something’s gone awry. These LEDs (also called Debug LEDs) 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. This initialization phase occurs right after you turn on your computer and is called the POST (Power-on-self-test). These red (or orange) LEDs on your Motherboard indicate that something has gone wrong in the process of initializing all of the hardware components that make up your PC.
