So i am currently upgrading my PC. I had 4GB DDR3 Ram and i bought 8GB DDR3 1333 MHZ Ram. After installing it ike the instructions on a website told me. The PC beeps alot of long beeps.

Old Ram wont work either.

My motherboard
ASUS H81M-A

If your not trying to use the old and new memory at the same time then install the new memory and reset CMOS.

Probably a noob question but how do i do that?

Unplug the power supply from the wall and remove the motherboard battery for a couple of minutes.
