I have LCD ADVANT model No: ADT15T display for your information.

Yeah thought it was going to be one of those crappy intel things. You may need an xorg.conf to define the dislpay better.

Thanks for the information.........but I do not know what to do?

Perhaps you could kindly explain xorg.conf

Do I have adjust the Display parameters on my computer (It was given to me free)

By the way, I am replacing my computer soon and was thinking of buying an iMac 27" what are your thoughts on this?

I am now getting more often COLOURED BARS on top half of screen some times soon after computer has booted up.

Still I have had no answer to this problem.

Please could you HELP ?

run:

gksudo gedit /etc/X11/xorg.conf

paste the below code, save the new file, close gedit then reboot:

If it doesn't make a display boot to recovery root console and rename the file then reboot

I have done what you said above but so far there seams no difference.
The computer crashed and went to what I think you safe mode and said something like Battery Low them rebooted when I pressed Ctrl Alt Del

I am new to Linux so please bear with me.

Could you explain a little more your line:- If it doesn't make a display boot to recovery root console and rename the file then reboot.

thanks

I'd test the ram. boot to live cd and when the stickman shows up, press spacebar, then select the memory test. Let it run a full test so we know its ok

Sorry I am new to this, I do not understand what do you mean by a "Live CD" and also "Stickman"
Please could give me more info on how to run a "Ram Test"

The LiveCD is what you installed with. This is synonymous with USB too as the data is exactly the same. The stickman screen is this:

See the stickman at the bottom :)
