Troubleshooting steps for "No POST", "system won't boot", and "no video output" issues
Troubleshooting steps for "No POST", "system won't boot", and "no video output" issues
Another one that somewhat relies on 16. I've encountered several instances where individuals are connected to outlets managed by a switch (many states mandate this due to building codes). The issue arises when the switch is switched off, cutting off power from the outlet. Also, ensure that if you're plugged into a GFI receptacle, it hasn't been activated. I've noticed some users employing larger power supplies that may cause the GFI to trip because of additional load.
In short, verify the power outlet.
Absolutely, we need to keep in mind that not everyone sees things clearly.
Discussing this further, is the PSu connected to the power source?
11. When using push-pins, have you confirmed that all four were firmly inserted? (The simplest method is to place them outside the case on a non-conductive surface such as the motherboard box. Follow the instructions carefully!) The pins should be turned in the opposite direction indicated by the arrows.
I also use a roll of packing tape or duct tape to hold the motherboard steady while pushing the pins.
Good article.
Other points to consider:
For troubleshooting, turn off the reset switch. If it’s damaged, the machine won’t start at all or will keep rebooting.
The paperclip trick with the power switch leads can help check if those connections are faulty—short circuits usually cause the PC to briefly power on before shutting down.
If the system stays on long enough for LEDs to blink and fans to spin, then it likely has a short circuit somewhere. This highlights why removing non-essential parts (like drives) during POST attempts is beneficial.
Keep in mind that disconnecting the GPU will often trigger an alarm about lack of power. If your motherboard supports it, use onboard video for early testing.
Regarding troubleshooting, back then we used more expansion cards. If I encountered an issue, I would remove the extra cards and test with just the video card and motherboard. I believe a setup of motherboard plus RAM plus CPU is the bare minimum needed to get the board to start up. You can confirm it's working by checking if the CPU fan is running. Once confirmed, add a video card so you can observe its activity. Then connect the drives as required.
