Hi,

Anyone knows what could this problem be? It doesn't even get to the login screen...

I am unable to tell what is on the display; is it the BIOS setup utility, or a Windows screen? If it is in Windows, do you have another monitor you can try with the laptop? (Note, you need to press a couple of keys to switch to an external monitor., usually it is Fn + F5)

It is the Windows Startup Repair screen. The computer can't reach the Windows logon screen.

I've already connected an external monitor, but the same happens. The external monitor displays with those "scan lines".

Do you see the lines during power on self test, before Windows starts to load? That would likely be a memory or graphics controller problem. If the power on self test is ok and the problem occurs after Windows starts, then I would suspect drivers. Have you tried starting Windows in Safe Mode?

Yes, I see this problem as soon as I start the computer. The "Toshiba" start-up screen, also appears this way. Could this be a Graphics controller problem, then? The GPU?

If you see it as soon as the computer is turned on it is a hardware problem. Unfortunately for 99% of all laptops the graphics adapter is integrated on the motherboard and repair would require replacement of the motherboard. What is the exact model of your laptop as read from the label on the bottom of the laptop?

Hi dustjay. I have:

Toshiba A300 - 1CO

I plugged that model number into the Toshiba site search and it either comes back as a Power Adapter or "No Results"

Sorry I did not realize you were not in the US. With my extremely limited vocabulary of Spanish, I was able to pick out the Graphics and yes it is integrated and will require a Motherboard replacement to repair.

The Graphics is:

ATI Mobility Radeon™ HD 3470 with HyperMemory™
Memory: 256 MB VRAM dedicated (up to 1 023 MB with HyperMemory™)
DDR Video RAM (shared DDR Video RAM and system DDR memory)
Bus conector: 16x PCI Express

Too bad I will need a new Motherboard... Is it easy to replace? And what specific model should I look for?

Thanks.

You would have to get the motherboard model information from Toshiba. It will require complete disassembly of the Laptop to accomplish a replacement. Is it Easy? I would not tackle such a task myself. The price of a replacement motherboard can be as much as the price of a new Laptop.
