Acer Laptop Screen flashes all different colors - Going crazy!

By vcongion ·
Hey friends,

I've got one that?s got me stumped. Myself and one of my employee's have looked at this one and we still seem to be having the same problem. The initial problem was the motherboard so we installed the board, loaded up the laptop and everything worked fine. We then decided to do a clean install of windows media center 2005. We used the ACER installation cds which are bundled with all of the drivers. After the installation was complete and windows loaded for the first time the whole screen would flash repeatedly with bright colors. We immediately thought we got a bad MB.

After installing a new MB the same issue occurred. We are able to get into windows but eventually the screen flashes. We tried uninstalling the ATI video drivers and as soon as that happened the screen flashed. We also attempted to start up in safe mode and were unsuccessful with removing the drivers. I would appreciate any suggestions! Thanks.

Acer laptop - what model and number?

"The initial problem was the motherboard so we installed the board.. ..After installing a new MB the same issue occurred."

So, including the original motherboard, that's THREE motherboards up to now, correct?

Without knowing the model of Acer laptop yet, I can only ask what ATI graphics card is fitted to this Acer?

Does this system flash repeatedly with bright colours immediately - or only once Windows has booted up?

Like the Model I would say look at the manner that you installed the OS & Associated drivers as the problem here.

Quite often Device Drivers need to be installed in a certain order to work correctly. If this order isn't followed you can get all types of Screwy Symptoms occurring. I'm assuming here which is always a dangerous thing to do that you haven't tried any newer ATI Drivers as well so maybe that would be a good starting point to attack this unit from.

The other thing I would look at is the Leads that attach the Monitor tot he M'Board and double check the connections here. It's not unknown for one of these leads to break and need replacing and it's also not unknown to have a Ribbon Cable connector fitted the wrong way round on a new M'Board. You can not just believe that different M'Boards are identical as many are not.
