Computer will not boot at all, even into BIOS

Posted on

Problem :

I asked a question a few months ago about my computer randomly shutting down, but not powering off, i.e. the fans were running but no input was taken and the screen didn’t come on. It happened again today, and now I can’t turn my computer on at all. I hit the power button, and the fans spool up like normal, but nothing happens. No USB power, no nothing. The one thing that is really odd is that the silent mode and stop lights on my graphics card (I have a Gigabyte Windforce GV-R938G1 GAMING-4GD) will flicker twice about every 17 seconds. They also do this on startup, just without repeating. This leads me to believe that it is a boot loop, but I don’t know how to break the loop and I don’t know what could be causing it, or even if that is what’s happening. I have tried power cycling, leaving it off for a while, leaving it unplugged for a while, and unplugging the reset switch in case of a short. This is my own, custom-built computer. Specs below, any help much appreciated.

Just got my board back from RMA at Gigabyte (after well over a month) and it still does not work. While it was gone, I tested my power supply with a multimeter and got essentially perfect readings from the CPU, GPU, and motherboard cables. I also got a speaker to listen to the POST codes and there is nothing. No beeps. I have no idea what this could be.

Solution :

Unplug all your cords and hit the power button for 10 seconds to drain any remaining power , next is remove all your RAMs and try to boot without the RAMs if it successfully boots then start adding RAMs one by one to check which one is faulty sometimes removing your CMOS battery and resetting your bios would do the trick but I recommend that you take a look for any flashing LED lights on your case cause sometimes they indicate what’s the issue with your PC if so, please check the manufacturer diagnostics with LED lights to explain what’s going on with your PC .
