Hi
I am suffering the BSOD displaying that the file nv4_disp is at fault.
This error is causing my PC to crash everytime I try to start it.
Sometimes I manage to get onto one of the profiles, but I am unable to get the computer to respond to any mouse or keyboard input, before finally displaying the BSOD
The rest of the time, i just get vertical coloured lines across the screen before going to the BSOD.
I can however access via Safe Mode with no problem.
I have vacuumed out all the dust from inside.
No hardware changes have been made for some time.
My kids have been playing heavily on Minecraft.com lately and downloaded programs to do with that, which is the program that was running when this problem first came to light (according to my daughter this wasn't the first time she had such a message, but was normally able to restart ok).
I am running XP SP3
Graphics Card NVIDIA GeForce 7300 GS, last updated 11/8/2006, version 9.1.4.7
Have seen problems on internet from other users, but wanted to contact you before trying anything suggested
Look forward to your help
The NV4 file has to do with a corrupt Nvida video driver or your Video card is either not seated correctly or needs replacing.
Firstly I'd check that the Video card is seated properly and then go with the driver possibility as it costs nothing.
Boot to safe mode and go to Start / right click on Computer / manage / double-click Device Manager / click the wedge shaped arrow next to "Display Adapters" and then double-click on your Video Card / now click on the Driver tab / click on Uninstall driver.
After the uninstall you need to boot into "Safe mode with networking", not Safe mode.
download this latest video driver from here to your desktop.
Install the driver . If that doesn't clear the problem, I think your Video Card needs replacing.
Thanks Lee for your quick reply.
Have just done all the above and we're sorted.
Was this error caused by anything in particular do you think, or was it just a 'natural' fault that happens in time?
the driver probably got corrupted somehow, but knowing what/how caused it is impossible to say for a certainty, my usual guess for such things is a hard drive read head crash.
no it's not a "natural fault" that you'd expect to happens, but then again it's also not that unusual for data/drivers to get corrupted somehow either.

I kinda supect this, it may have installed something that could have corrupted the driver.
Well it lasted about a week and now the BSOD is back, though this time with a new message:
'Check to be sure you have adequate disk space. If a driver is identified in the stop message, disable or check with the manufacturer for driver updates. Try changing video adapters.
Check with your hardware vendor for any BIOS updates. Disable BIOS memory options such as caching or shadowing.'
No specific driver is identified as being at fault.
Is this fixable, or is it new grahics card time?
Go to Start / right click My Computer / Manage / Device Manager (any yellow exclamation marks there?) / expand Display Adapters / double click on your video card. Does it say "this device is working properly" ? If so, click on driver tab.
What does it say next to -
Driver Provider:
Driver Date:
Driver Version:
Cheers,

Hi Lee
No exclamation marks in Device Manager
As I'm only able to access the computer via Safe Mode, the device status is unavailable
Driver Provider: NVIDIA
Driver Date: 07/04/2011
Driver Version 6.14.12.7061
Cheers

Disable BIOS memory options such as caching or shadowing
I'm not confident you even have such a thing in your Bios (it's usually in older systems) but it's worth a look and a try if it is there, but it is a bit of an antiquated Microsoft message.
The BIOS can be accessed during boot by clicking a specific key. Typically, the key is indicated by a message on startup. The key could be F1, F2, DEL, or F10, F11 or f12. If you don't know which one it is, hit the DEL key several times straight after bootup. When you see the Windows logo you know it didn't work, try again.
Once in the BIOS (navigate with keyboard arrows and use delete to enter a section and escape to leave) you might find an option to enable or disable BIOS caching or BIOS shadowing. The option could be called 'XXX' is cachable. (Enable/Disable). To tell you exactly where to find the respective option and what it is called, I would need to know your BIOS manufacturer and version.
Done this, but no better.
In fact it's got worse as I can't even access the computer via Safe Mode now.
If I let the PC boot normally it starts the DSKCHK routine every time
You are going to have to get into BIOS Setup on your computer to set the CD/DVD drive as the first bootable device, so you can then boot your XP CD, unless it provides the ability to press a Fn key at boot time to bring up the boot selection menu. If it does, use that.
How you do this varies with each manufacturer. Normally you press F1, F2, F10 or Del when you see the manufacturers logo. Often there is a clue somewhere on the screen when you boot normally telling you what key to press. Some computers (most newer ones) have a key you can press (often F12) to bring up the Boot Menu from where you can select the CD/DVD drive to boot from.
If you don't have an XP CD, download and run ARCDC by Artellos. It will download the required files from the Microsoft Web site and create a .iso file. It will also offer to burn the iso image to a CD for you. If you don't do it then, there is a good freeware burner called ImgBurn which will do it at a later time. If you're unsure how to do this, you can follow the tutorial here: How to Burn an ISO File. This can be done from any computer.
Boot the CD and at the first opportunity, enter R to start the Recovery Console.
Next, choose which XP installation you want to login to. Normally this will be 1.
Lastly you will be asked for the Administrator password. Just press the Enter key as the Administrator does not have a password (unless you gave it one, then you would enter it).
From the command prompt, enter: chkdsk /r
Allow it to complete undisturbed. It can take an hour or more depending on the size of the hard drive.
Remove the CD, type exit and the computer will reboot. Hopefully that will have fixed the problem (corrupted file system).
If that doesn't resolve the problem, boot to the Recovery Console again only this time do this:
Type chkntfs /x C: (Note the spaces before and after /x)
This will prevent chkdsk from scanning drive C: at startup. Reboot and see what happens.
To reset it to normal again open a Command Prompt, type chkntfs /d and press Enter.
Cheers,
Lee
