My computer turns on, but nothing shows up on my screen (except the dell colour demo). I used the Asus Motherboard diagnostic (because i have an Asus P8Z68-V) and it asked if i heard a noise. I couldn't, and it asked me to remove my graphic card and RAM. I did, and i heard a long beep and then two short beeps.
What does that mean? all my parts are operational (atleast the fans are) and i checked to see if my wiring was in properly and it looks fine. Also note that there was a lightning storm nearby my house, which might be the cause.
