Hi AJ
If its a continuous Long beep than it can posibly be eighter the Keyboard, Power Supply or worst case scenario You're Mobo. Even though it doesnt sound like a keyboard issue seeing you cant even get a display, Ill recommend that you borrow a keyboard and a PSU (Power supply) from a buddy to run the test. Chenge them on e at a time

What is the BIOS on your PC.
AMI,Award,Phoenix,IBM or other.

AMI/ Award/Phoenix
1 long beep indicates memory error.
Try cleaning and reseating memory modules.
IBM
1 continuous beep indicates failing Power
Supply (or worse scenario failed motherboard)

Apologies sittas87, your reply came as I was typing.I tend to agree that it is most likely the PSU or motherboard.

To be specific the model type does apply. But in most cases this will be the case.
Btw, no need to apologies we're all here to help ;)
