Pc black screen

[Mikeleeee34]

Good afternoon,

I recently changed my ram speed from 1777 to 3200 since that speed is quite low. After that the pc is starting but all black screen

I tried to reset the COMS but nothing, taken out the battery, pressere the power button for 60 seconds and after 15 minutes I put back the battery but nothing. I tried to change the cpu and ram and removed the gpu to see if it's working but the motherboard won't allow it. I am trying to find some bios update or new bios to download on my other pc to a USB but I can't find it. Any help ?
