My OS:Windows Xp, Home edition.

Starting off, a couple of days ago while browsing facebook, and logged into starcraft II. I started getting screen static and then a blue screen to a shut down. The blue screen error was explained by a nv4_disp. Which I googled and seems to be a video card error.

I did a file recovery and had a friend of mine reinstall all the motherboard drivers and 90% of the drivers needed to run my pc. The only one we didn't install was the newest version off the nvidia website. Due to a time restraint. So we just downloaded the regular drivers that I recieved when purchasing the 8800 GT GPU. (The disc). When I got home I wanted to make sure all my drivers were up to date so I proceeded by going to nvidia to get the latest driver for my 8800 GT. 5 minutes after the complete install while browsing the web looking for latest drivers off all my hardware, I got a blue screen again. This time not explaining but just flashing and shutting down my computer.

Now I know this is what was suggest, and this is what I did.. so should be a easy fix right? --> boot safemode uninstall and reinstall newest drivers for my video card. (8800 gt).

But it didn't take the "newest" updated drivers. But handled fine for several hours with the (disc drivers recieved with my GPU), while installing the rest of the drivers/networking etc.. with my "IT friend".

Now I'm wondering if I should uninstall the video drivers I installed and then procceed to install the drivers on the disc that came with my GPU. Problem being it's not the latest driver. I'm not the smartest with computers so what will this affect? or is there a fix to my problem that can allow the newest drivers to run without causing a blue screen.

I'm able to get into "safemode" and with "networking", but not able to access "last working configuration" (or however that is written).

Please help! I'll be watching the post all evening and through the weekend/next week. So I'll be responding to answers rather quickly

I ALSO FORGOT TO MENTION that there are dollar signs on the loading screens!

Umm when I boot the computer dollar signs take place of alot of the letters. Even the boot menu.

I think its called file recovery... Basically cleans off all the drivers and other stuff.. Kept all the programs though.. not sure the technical name for it.

You'll have to ask your friend, what exactly was done, because I'm not sure what you really did.

Nothing but driver/motherboard install was done. I watched him do it all.

The problem is that after I installed current drivers the computer stopped working again. The same drivers that possibly caused the first crash..

No I did a system recovery. Wiping all settings and drivers.

We used my motherboard CD + other driver cds for the basic drivers of the computer.

When I wanted to get "fancy" and install the newer drivers on the manufacturer's website is when the problem happened again. (blue screen, dollar signs for letters, not letting me out of safemode unless I UNINSTALL all video drivers.)

Now, I guess, I understand.

What type of CD did you use to run recovery?
Some recovery CD, or regular Windows XP CD?
Do you have any errors in Device Manager?
What computer brand and model is it?

My computer "everex" walmart special. Was basically rebuilt by me. The only thing I kept was the 120 gb hard drive. The recovery system of this computer you just press "r" on boot up and you get a recovery menu. Similar to ones I've seen that use a CD.

I have a few "!" Errors in the device manager. 0ne being my "Nvidia GeForce 8800 GT". And the other being "Audio device on High Definition Audio Bus". (which remembering now.. the only two drivers I installed before the second crash was "realtek sound" and the nvidia graphics card drivers).

So possibly the sound driver caused all this?

Brand was everex but like I said it was rebuilt.

Amd Athlon™ 64 X2 Dual
Core Processor 5000+
2.61 Ghz, 2.00 GB of RAM

Microsoft XP
Home Edition
Version 2002
Service Pack 3

Not sure that's what you need for information.

I'm also on my computers desktop right now. (using my laptop for this website though). I was able to get to the desktop when I went into device manager and completely uninstalled all video drivers.

I'm able to access the internet and what seems like all the programs that don't require graphics to run.

I still get the dollar signs on boot up. But I don't get a blue screen restart,... rinse and repeat session.

When you run a recovery like that, all drivers should be already installed, so there is no need to play with them.
Right after recovery and before you guys started to monkey around, was everything working just fine?

Trust me no drivers were installed. all the "found new hardware" messages were popping up.
