I don't know much of anything about how computers work and the terminology regarding computer hardware, so bear with me.
My older brother recently switched my broken graphics card for a new one, as well as added another stick of RAM to my computer. Everything was fine for about 10 minutes, then suddenly the computer froze completely and a buzzing sound was coming from my headphones. I reset the computer manually and now it won't boot up. It freezes at the "Press TAB to show POST screen,DEL to enter SETUP, ALT+F to enter AWDFLASH" screen.
Help would be much appreciated.
Edit:Sorry for the cut-off title.
