post #1 of 15
Thread Starter 
i just got the cpu and installed it on my motherboard for some reason it isnt working my keyboard and mouse wont show up and my screen remains black?
i downloaded the f10c bios update and still hasnt worked?
Did i install the bios wrong or forget something any help would be appreciated.

Can you confirm that there's power to the motherboard to rule out a dead/bad power supply?
Do any of the fans spin up? Check your CPU 8 pin connector as well to make sure that it's plugged into the board.

Does the motherboard issue a post beep from the PC speaker? It should be just one quick beep if it's posting properly.

ANyways make sure all plugs are plugged in such as the 8pin and 24 pin cpu and motherboard connector.

Graphics card installed and pci-e plugs are plugged in?

Tried a cmos reset?

If you've got a graphics card, try reseating it to narrow it out.

If you wanna CMOS reset, press the 'clear CMOS' button on your board if you have one, or if you don't, you can short the CLR_CMOS jumper on your board while it's off, or take the CMOS battery out for 2 minutes to let the settings reset themselves.

If it still doesn't post then, reseat/check your RAM, and check that your CPU has been lowered into the socket correctly.

If your old CPU works fine then it will definitely be a dud CPU. Is it still under warranty so that you can get it replaced for a new one?
