Display issues

A few weeks ago i had this problem with my toshiba satellite m30

The screen began freezing and the music playing started stuttering. It then froze completely so i held down the off button to reset it, It then wouldnt boot up at all, (or so it appeared) the lights came on but nobody was home.

I settled on my idea that it was a motherboard problem and hunted down a cheap motherboard online (same model etc)

It arrived yesterday and I fitted it into my laptop and put everything back correctly, booted it up and noticed these funny lines on my screen. They looked kinda like glitch lines you'd see on a gameboy or something, and finally when it completely loaded most fo these faded till there were a few that just resembled dead pixels.

After booting again it crashed, I started it up straight after and it got to the "windows was not shut down properly" screen. Some of the letters were missing in random places and were replaced with funny symbols like "matrix" text.

Now it seems im back to the dead screen stage with the occasional previous things happening.

Anyone know whats going on?

Advise me

cheers

 

Anyone?

 

Well it is not the motherboard, it is either the lcd or the graphics card.
The only way to tell, is to use an external screen. IF the problem occurs on the external screen, than the problem is caused from the onboard graphics card.
If no problems occur through the external screen, than the problem is your lcd screen.
To fix the lcd problem, take the plastic bezel around the screen off. Then as you take the lid apart, you will gain access to the back of the lcd panel. You will see a ribbon cable running up the back the screen. Unplug the cable from the back of the lcd, and clean the connection with small amounts of rubbing alcohol, if it is needed (use a q-tip, and make sure its dry before reconnecting).
Then reconnect the cable, and make sure that it is connected all of the way. Then use a piece of tape to cover the connector and use a piece to tape the cable in place, so that it cannot be disconnected again.
Than put your laptop lid back together and let us know if the problem still persists.

Yeah, I plugged it into an external monitor and it appears to be the onboard graphics. Can this be fixed at all?

 

Wait a minute. If you have on-board graphics then by replacing the motherboard you are also replacing the on-board graphics. This may actually be a hard drive going bad.
You can download the "ultimate boot cd" (google it it's free) and run the HD diagnostics.
Also make sure everything is securely plugged in your new motherboard especially the LCD ribbon.

EDIT. Download one of the many free Linux distro's Live CD (Ubuntu, OpenSUSE etc.) burn the iso and boot from the CD (make sure your BIOS is set-up) and see if you still have the problem. If it boots fine then all the hardware BUT the hard drive are OK.
Good luck

 

Well, the graphics not working, is some kind of internal conflict. Since your system has an onboard graphics card, that means that with your new motherboard came a new graphics card. I dont think that you got a DOA motherboard, but it is very strange. If the problem is occuring even on the external monitor, their is a connection issue somewhere along the line. Make sure that all of the cables are secured all of the way, and that the memory and processor are properly seated. If the lines continue to appear, than I suggest RMA'ing your replacement motherboard, because it must be caused by the motherboard.
