I used the restoration CD's twice and no effect.

Any idea how to fix this?

    Same or similar problem here. Yesterday I found my laptop with a black screen and it wouldn't respond. I did a hard restart (holding the power button). During restart, the screen looks okay at the initial view (Qosmio written across center), then it goes to garbled text and symbles (black and white only) - taking up the entire screen. After a little bit the Windows logo comes up like its booting into Windows, only with several rows of blue dashed vertical lines on the screen. After another little bit, the screen goes blank and finally a blue screen indicating the system shutdown to protect it from a serious error - complaining about a file nv13-disp (I think - may have to double check that). How can I fix this - without spending $500 - 1000 on a new system board?

    I am having possibly the same problem with my client's Toshiba Qosmio G25-AV513 PC Notebook. At the start of boot up, the QOSMIO logo looks good, and hitting F12 at that time will allow me to select between hard disks and CD drive to boot up from. But otherwise, just letting it boot up from the hard drive and letting it go through the DOS mode where messages are posted in black and white, but I can't make out anything, because the screen looks all scrambled with a repeating black and white patterns that covers every character position, although it looks different wherever the characters are supposed to be.



    I can do an F8 to go into safe mode, when it settles to a cursor waiting for the enter key, I know that it is asking for whether to go into safe mode, I can't read anything but I can guess where to move to with up keys to get to the safe mode line. From there I can hit enter and it will go into safe mode where it does work and look good, after it passes beyond the Windows logo which shows some columns of marks. I have noticed in normal boot up that it does go to a blue screen that says it has to reboot for safetye reasons and doesn't give me enough time to read the rest of the message.



    Anyway, I tried installing newer BIOS and that didn't help any. I tried an Ubuntu live CD and I can get it to load and run it. I haven't tried an external monitor yet.

I extremely recommend DON'T do anything to the computer. Unless you plan on buying a new one anyways, don't bother fixing it on your own. blue screens are caused by one of hundreds of thousands of problems.

take the computer to a near by repair center and have them EXAMINE it. many of the issues can be solved, but be sure the is one of those cases. then get a quote on how much it will cost to fix.


You will need to do a Backup Before all your files are lost.
Good Luck

I want to upgrade my Toshiba Qosmio G25-AV513 to windows 7, but I understand that some of the programs will not function properly due to the old hard drive. Is this true or is the company I called for...


Uhm. I am typing this from a Qosmio G25-AV513... Using Windows 7.. With the original Hard drive.. Someone is lying to you. Lemme guess.. Best Buy?? Anyway.. It wasn't a totally straightforward upgrade.. You will need a little computer knowledge (finding drivers, ETC.) And since this computer came with a RAID setup, you will need to download the windows 7 raid drivers, and put them on a thumb drive BEOFRE you start installing, because when you get to the install screen it won't find a hard drive, you have to put the thumb drive in and click "Load Drivers", then load the RAID driver and it will work.. Drivers are kind of a pain to find since Toshiba didn't update their website with Vista or 7 drivers.. Thanks Toshiba. If you need help, e-mail me. P2000Canaro@gmail.com. Good luck!

Display has vertical white lines. Hook up a external flat screen and it works fine . Toshib Qosmio g25


this indicates you have a bad screen, and if you press around on the back (top) of the computer display the lines will disappear until you take your hands off the area effected, and the screen needs to be replaced.

Spilled Water on Toshiba Qosmio G25-AV513


If you are pretty good at computers then you can open up the computer and see just how bad the damage is. You may need to replace the keyboard, or a few parts of he mother board. If it was water I think you would have more of a chance, but the sugar will definitely cause problems if it hit any circuit boards. Your best bet is to take out your hard drive, make it an external hard drive and get a new computer.

Qosmio g25-av513 disassembly


Hi Paul have a g25-av513. First disconnect and remove both hard drives and the battery. In the battery compartment there is a small screw you need to remove and in the hard drive 2 bay there are 2 f8 screws that need to be removed as well. In all there should be 17 screws that need to be removed before you can pop the back cover off. When removing pay close attention to the connectors attached to the underside of the back cover. be careful not to pull to hard or you may tear the connectors which are very thin wires. First you have to remove all the screws on the underside of the laptop. The screws are marked f8's and f16's the longer ones are the f16's of course. I have taken mine apart several times already due to a boot up shut down issue which I believe is related to the modem board underneath hard drive 2. It seems that when ever I disconnect and reconnect this board my power shut down issue disappears. If it happens again I'm going to remove i all together and see if that takes care of my problem.
