To me this is a hardware problem.

Let's diagnose, and see Shunka_Reid.

A) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port, on the laptop.


Number 3 - External VGA display port

General example of VGA connector (port), and VGA cable,


Scroll down a little for the VGA cable example.

You can use a CRT type of monitor, (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable.

B) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By factory default settings, the display should show on the external VGA monitor.

IF not;
There are at least 3 display options available;
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor.
3) External VGA monitor ONLY.

Press, and hold the Fn key down, and at the SAME time tap once on the F4 key.
The F4 key is the Display Toggle-Over key.

Still no?
Hold the Fn key down again, and tap on the F4 key once more.

Do you get a good display on the external VGA monitor?
Post back in a Comment.

Also, has the laptop ever been cleaned on the Inside, to your knowledge?

I think I might have the same issue. I have an NV7919u and I have noticed that several times after emerging out of "hibernation", the screen has columns of strange looking black lines from top to bottom of the screen.

What I have found is that if I open an application or maximize one that has been minimized, it clears the screen. I am sorry that I can't help much more than that but I am also looking for the cause in the event I had an opportunity to repair it...!

I can't tell you that... but if you want to get it work again, install the newest drivers from NVidia and it should work.

Did it come with Win8 installed already? Was it ever working before? Or did you install Win8 on this machine and now it won't boot up?

what are you trying to do? if your trying to recover from the partition and it is not allowing you to do so, you may have corrupted the restore partition. or you let the 30 days expire and you have no choice but to reinstall or purchase a legal license. Either way, it may be best to contact gateway for original disks (usually a minimal fee) and once your back up and running, make sure you make a set of recovery disks before you do anything else.

If it is a new hard drive it could need formatting or if it already has software loaded it could need the drive formatting on a different machine.

I have noticed something strange, probably in the bios settings of one computer I had contact with recently. It resisted all attempts to load an operating system on an empty drive but loading an operating system with a different machine and then reinstalling the drive in the original it accepted the new operating system without any further hitches.

Another thing to think about was the time we tried to take a look at a hard drive and all my friend's machines refused to read it.
It turned out his machines had 32 bit operating systems and the fresh hard drive was on 64 bit.

If loading restore from F8 just before booting doesn't work, you may need an OS disc to restart your laptop.

If it booted up before, put the old drive in then see what happens.

Okay, whats happened is that you either have a program like Bitlocker turned on, or some security feature enable on your hard drive.

If you want to get into BIOS press either F4, F2, F1 or DELETE. Most of those keystrokes will enter you into your BIOS. Unless your BIOS is locked with a password, in which case you'll need to get a device code. If this is the case you will need to contact the manufacturer and speak with them about your issue, which will require your serial number and model number.

As a back door last resort, you may be able to put your Windows OS disk and do a install over the existing Windows image. Make sure you have a real windows OS disk, not a recovery disk. Let me know if any of this helped you.

Can you be more specific? What do you mean by "factory reset"? It sounds like you get to the windows password screen, then you get a blue screen instead of your desktop, is that what's happening?

It sounds like you may need to put in your install disk and reinstall your version of Windows. Can you give us some more details? Is there an error message or anything on the blue screen?
