Question Installed ssd m2 and now pc never boots again (no signal black screen)

[JohnVR]

Please help, I need to work…

Specs: motherboard b360m aorus gaming
Tried installing a m2 ssd pcie 500g in it

Installed it (with the special screw)
Tried booting
Result was that my pc was booting and turning off each 3 seconds by itself
Resetted bios by removing battery
Now it turns on normally but no screen (black, no signal)

I removed the ssd and the screws
Replaced the ram
Resetted bios via those 2 pins
Tried plugging the hdmi of monitor into the cpu instead of gpu

Everything resulted in the same.
Leds and fans always on (fans of cpu also on)

Thanks in advance
