Hi all, when start button is pressed, the monitor is blank, no start screen, can't boot into windows. Motherboard light is not on. However, all the fans are running, PSU fan, processor stock cooler fan, casing fans are running. RGB of cooler fan is working.

Debug light on motherboard show CPU with red lighting.

I am unable to press reset button.

Can only force shut down when long press power button.


This happened when I found that virtualisation setting on bios is disabled, it has been enabled for long while. It might have been auto reset back to default setting. Hence I wanna to boot to bios to update it. After that, when I restart, noticed it couldnt boot into window. At first the lights on motherboard were working. Then when I long pressed power button, the fans and processor fans were not able to shut down, then I pressed the main switch on the wall to force shutdown. After that when I switched on the pc again, the lights on motherboard is no longer working.


System:
2700x Ryzen 7
Gigabyte Aorus x470 Ultra Gaming
4 x 8GB DDR4
One graphic card

Help needed. Thanks

I have tried with the ram sticks, tested with all the slots. Now even the processor fans and ask the fans stop working.

However, there is still a flash of light on the motherboard for a split second when i turn on the psu switch at the back with the ram on..

Does your pc come with a buzzer? If it does, take out the ram, gpu and everything else except Mainboard and CPU. Power up and see if it beeps, if it doesn't beep at all, it could be a faulty Mainboard / CPU / PSU; if it beeps, mainboard and CPU are most likely fine. Check the post beep code to figure out what went wrong.

Try checking the RAM first, and then test the mobo.

Clear cmos 1st, start from there. Check your user manual on how to do it

assuming this is the culprit, unplug all your psu cables into the mobo (remove all power source), remove the cmos battery and leave the mobo for like 10 to 15 minutes. then try again to boot with just 1 ram stick.

Unplug everything then install each part 1-by-1 outside of the case
Remember to remove the CMOS battery while unplugging all the hardware so the CMOS memory will be cleared

If you have multiple SSD/HDD, install the main SSD/HDD first that is being used for Windows
If you use multiple RAM sticks, install 1 stick first followed by the other
