I changed my ram speed from 2666mhz to 3200mhz after getting my new ram (Corsair vengeance 2x 8gb ddr4 3200mhz).

After the update i tried to start my pc, but the screen doesn't turn on/no signal, keyboard and mouse don't light up and work. Only fans and motherboard leds work. I tried removing the CMOS battery, but it didn't work. What should i do??

    Hi, I am Dave, I will help you with this.

    Disconnect the power cable from your PC.

    Press and hold the power button on the case of your PC for 30 seconds.

    Wait 30 minutes.

    Reconnect the power cable to your PC, then start it up, does it boot up correctly?

    If not, if you have more than one stick of RAM, remove a stick and see if you can get into BIOS to remove that profile you have set on your RAM.

    If that method did not work for you, seeing as you can open your PC to change the RAM, remove the CMOS battery from the motherboard, and then perform the above steps again to see if that can reset your BIOS.

    Removing the Cmos helps

    Nope, nothing happens. The fans start and the leds light up, but no sign of life on the monitor or the keyboard.

    I changed the ram to my old but it hasn't helped at all.
