It's all gone wrong! *sobs*

Always post your specifications - saves time.

Disconnect all external and internal components and only run with bare minimum components. If you have an onboard video card, use that. Make sure CPU has a stock cooler properly installed, the motherboard has ALL POWER SUPPLY CONNECTIONS MADE if ATX. Please read manual if you are unsure.

Then, boot up the system. If it still does not show anything - your motherboard or display card may have a problem.

Please connect a PC speaker to the motherboard (beeper) and hear the number of beeps.

I tried disconnecting things to the bare minimum and no joy. Everything is properly connected.

No help.

Follow all the instructions in my post and please post results.

I get no beeps...

Do you have a case speaker connected? wont hear any beeps if not  
Moto

I believe it has one built in.

see if you can locate the speaker on the motherboard... it is a black cylinder with a dotted opening on the top surface. Read the manual to see if it has one.

or see if your cabinet has a cable that says speaker (4 pin)... along with power hdd led and reset cables.
