I had the bsod (nv4_disp) and when i looked on the net i was told to start in safe mode with networking and download the latest driver. Uninstall old driver then install updated one. This i did but when i start up again the computer screen flashes.. Please help

Unplug, remove battery, plug in, reboot, start tapping F-8 repeatedly, select safe mode with networking. Uninstall the Audio adapter, download the drivers for Win XP here: http://support.gateway.com/support/drivers/search.asp?st=pn&param=3500728

LOL, you are going from one terrible product to another one. Norton and McAfee are core hogs, use a lot of resources and will slow your system to a crawl, especially if you let it expire. Why would you want something on your system that is so difficult to uninstall? Give em the boot. Try one of the FREE Antivirus programs such as AVG, AVAST or Microsoft Security Essentials.

Dell did not create this monster, your third party software is the culprit and they just don't deal with it if it's not their product.

Anyway if you tried the normal uninstall by clicking Start/Programs and opening the McAfee Folder and clicking uninstall and you're getting the BSOD, maybe try uninstalling it in Safe Mode With Networking.

Turn off the computer, then hit the power button to turn itback on and immediately start hitting the F8 key repeatedly until you see SAFEMODE. Take the Safe Mode With Networking option and let it boot up. Safe Mode will lookdifferent to you, the screen will be darker and the icons bigger, this isnormal.You can also go into the Control Panel and Uninstall the Program. Click Start/Control Panel look for Program and Features or Programs or Uninstall.
You can try the McAfee Removal Tool. Download and Install it, then run it. The link is below:http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe

Start safe mode with networking enabled, in safe mode uninstall the graphic card drivers.
Reinstall the latest driver from the manufacturer and try to set up display resolution again.

What happens when you try to boot? Are you getting BSOD (Blue Screen Of Death) or does it just reboot again? Keep tapping the F8 key which will take you to the advanced boot options. You should select Safe Mode with Networking, which should load windows with minimal drivers. Once you are in Safe Mode with Networking, you can either do a system restore to a time when your computer was working properly, or uninstall any programs, updates that you installed recently. Also try turning off Hibernation once you are in Safe Mode with Networking. If that does not work, reply back with the OS version

Try safe mode (F8 while booting) fi it will boot into safe mode, then it might be a bad driver.
Delete audio, video, network, etc (all but teh cpu driver) and resart.
Download the driver (if you don't have a disk) on a usb stick (on another computer of course) and reload drivers.

Load the computer in safe mode by pressing F8 before windows loads up. Once in safe mode, uninstall the drivers that you installed, reboot and download the latest ones from the manufacturers website.

I think if you download and install the most recent copy of Direct X, the problem will be solved.

Nvidia's recommendations for the 8800GT are 26 Amps (I think) on the 12V rail... Although you would think 20 Amps would be enough, my next step would be to uninstall the video card driver again, get yourself a copy of a program called Driver Cleaner dot net, run the program in safe mode to completely remove all of the Nvidia driver, then reboot into Windows, download the latest WHQL driver for your card from nvidia's website, and see if that fixes it. If not, either try the card in a system with a more powerful power supply, or get a more powerful power supply, and see if your error goes away.

These kind of problems can be caused by a number of different things, from software to dodgy ram, PSU etc etc. I'll assume you've already done a virus and adware scan-if not, do it now. If that doesn't work, let's start with the easiest to diagnose and fix-the device driver itself. Download the latest version of the Ati catalyst driver from Ati. Uninstall the existing driver(Assuming you're using Windows XP, Start>Control Panel>Add/Remove Programs, then find the Ati graphics driver on the list and remove it), remove the grapics cards entries from Device Manager(Start>Control Panel>System>Hardware>Device Manager, then click the cross next to "Display Adaptors", right click and choose "uninstall"), and reboot into safe mode (tap F8 at POST screen). Run drivercleaner in safe mode (you can download it from here): http://www.driverheavendownloads.net/ then reboot, cancel the "Found New Hardware Wizard" which pops up when you restart windows, and run the new driver installation program.
