How to Fix ‘New PC Build Won’t Boot’ Issue – Guide
If your computer won’t turn on – no fans are working, no LEDs are flashing, and nothing appears on the screen – you probably have a problem with the power supply. Unplug your computer and plug it directly into an outlet that you know will work, rather than a power strip or spare battery that might fail.
Make sure the power switch on the back of your PSU is turned on, and if the wall outlet is connected to a light switch, make sure the switch is also turned on. If you are using a laptop, make sure the charger is connected correctly and in the correct port – if charging via USB-C, only some of the USB ports may be providing power. A faulty power supply can often cause startup problems, even if the fans and lights turn on. If you don’t follow the troubleshooting steps in this guide, it may be time to replace your power supply.
Misplaced front panel connectors
The front panel connectors are a bit of a mess. It seems silly that we still have to tinker with a bunch of tiny wires while referencing the positive/negative schematics described in the motherboard manual, but that’s the way it is. The front panel connectors connect power button, Reset the drive activity LED button to a dedicated header on the motherboard, and an activity LED for the drive.
If you connect the power LED wires to the place where the power switch wires should be, nothing will happen when you press your case’s power button. Fortunately, connecting them in the wrong place won’t harm your PC. ..
Sheep Seated Incorrectly
When it comes to RAM, system administrators are usually very meticulous. They don’t typically rely on a few specific memory kits that the motherboard manufacturer has specifically qualified. However, you should make sure your USB sticks are seated correctly and that your computer is properly booted if you want to use them.
When installing RAM, be sure to align the notches on the RAM module and the DIMM slot. If they are lined up correctly, press firmly so that the tabs on both sides snap into place. Even though the RAM appears to be installed correctly, if your computer won’t start, try removing the modules and reinstalling them. ..
Missing power cables
Your motherboard needs power, as does the processor and graphics card. Depending on your specific parts, you may notice three or more power cables that extend from your power supply and need to be plugged in. If one of them is missing, your system will just stare at you without understanding when you try to fire it up. ..
If your computer is not booting, make sure the main ATX cable is connected to the motherboard. Some motherboards have a 20-pin connector. On most modern power supplies, the four extra pins stand out from the main connector. Also make sure you have connected the appropriate PSU cables to the motherboard’s 4-pin or 8-pin CPU connector.
Absence of motherboard deadlocks
Many modern cases come with spacers already installed on the motherboard tray, while others put them in a bag and leave them behind. You can put them where they need to go. These spacers elevate your motherboard so that it doesn’t come in direct contact with the metal tray. Otherwise you may have two problems. One is that the motherboard doesn’t align correctly with the case’s front I/O panel and, more critically, the second is that the motherboard can short out.
Different-sized motherboards use a different number of spacers. For a standard ATX motherboard, there are nine holes to align with the corresponding spacers. In general, you can get away with using less, but it’s a good idea to use all of them to ensure that your motherboard doesn’t move and is properly supported. Regardless, make sure your motherboard is not directly over the tray.
CPU overheating
If you’re experiencing problems with your computer, it’s important to rule out a faulty CPU. However, don’t forget that there are other possible causes of system problems, such as bent pins during installation. So if you’re still having trouble getting your computer up and running, be sure to check all the components for potential issues. ..
It is possible that your CPU is overheating. If your PC turns on briefly and then shuts down abruptly, it may be because the CPU cooler is not making enough contact with the processor. Alternatively, if you have an AIO cooler, you may not have connected the pump’s power cable. If this is the case, your computer may overheat and damage itself.
