Gateway MA7 has no Video after sucessful POST
Posted on 2010-08-15
I have a Gateway MA7 that fails to boot or display any video after an apparent successful POST. I can get into the BIOS, make changes, it displays the BIOS info, and the Gateway Logo, but after it completes the post, I get a black screen. If I enable battery learning, it will display the battery learning screen after post, but won't boot into VISTA.
It won't display to an external monitor.
No change if I remove the Hard drive, DVD drive, Battery, Memory or Wireless Adapter.
I have switched out memory, no change. I have replaced the HD, with a different one, no change.
It will not boot from a CD or DVD.
I have tried to run memtest on it but as I say as soon as the POST has gone through successfully the screen goes blank so I couldn't run memtest on it.
I'd be very grateful for any help on this.
