Problems with my video card

Nvidia / Geforce gt 330

Specs: Windows 7
I have an nVidia GeForce GT 330 video card, and I use Windows 7
Some months ago, I started experiencing problems. They would be different depending on if I used Windows Basic or Aero, but generally small squares of the screen appear somewhere else on the screen and flickering problems when scrolling in browser. Besides that I'd experience the eroor message "Display Driver Nvidia Windows Kernel Mode Driver Version XXX.XX stopped responding and has successfully recovered", which would often cause crashes when in games. I've also had blue screens but I'm pretty sure the blue screens are connected to the other problems.

The thing is if uninstall the driver, so it's back to it's basic version there's no problems at all (but since I can't really run any games or anything it doesn't really help). I didn't have this problem right when I bought it, so I figured it must have been an update. So I reformatted the hard drive which fixed the problem as long as I don't update the video driver, but again I have to if I want to play any games.

I'm really lost on what to do, and I don't even know if sending it to repair would help, so I would appreciate the help.
Oh and sorry for the wall of text.

"as long as i don't update the video driver"
does this means old video driver works fine?

"...sorry for the wall of text."

Don't be sorry. The more info you provide, the better.

"I've also had blue screens but I'm pretty sure the blue screens are connected to the other problems."

Quote the message.

A problem file may be named at the end of the text.

You may see a link such as "more Details" to more info - if so, click on it and see if it names a file.

You may see a message "dumping memory" or similar.

You haven't told us whether the computer is a laptop or desktop computer, or the make and model of the brand name system, or the make and model of the mboard if it's a generic system.

It's a video adapter, but it's NOT a CARD unless it's on a physical board that installs in a mboard slot and that can be removed.

"...flickering problems when scrolling in browser..."

That can be caused by a hardware problem with your computer or monitor, or by a specific video "drivers" problem.

"...generally small squares of the screen appear somewhere else on the screen..."

Those are generically called artifacts.

Almost always, you get those only when you have a hardware problem, not when you have a software problem.

If you get those while booting BEFORE Windows loads, that can't be caused by any software on the hard drive - that has to be caused by a hardware problem.
- if the video adapter is built into the mboard, probably either you have a ram connection problem, or are trying to use incompatible ram, or the video adapter or the mboard is damaged. If the video adapter is damaged, if there is a slot you can install a video card in, that will probably work fine

- if the video adapter is on a card installed in a mboard slot, it may have a poor connection to it's slot, or if it has a fan on it, the fan or the heatsink under it may be clogged with mung, or the fan may be failing or is no longer spinning, any of which will cause the video chipset to overheat . In that case, if the video chipset isn't already damaged, the video may be okay for a while after you boot your cooled down computer, but then you get the symptoms after the video chipset gets too hot.

If you DO NOT get those symptoms while booting BEFORE Windows loads.....

I've seen cases where a video adapter's chipset is damaged such that it works fine in plain VGA mode, but you get symptoms when it's using it's specific drivers in Windows.

You should not have problems with NVidia video drivers that worked fine previously, unless you didn't install them properly.

However, if you are now using newer or older NVidia video "drivers" than the ones that worked fine previously, NVidia has a reputation of not fixing bugs in their "drivers", unless it affects a large number of video adapters, and enough people contact them about problems with a particular version. .
You may need to find and load older or newer NVidia "drivers" from a web site other than NVidia's or wherever you got the present "drivers", e.g. if you have a brand name system and are using newer "drivers" than on their web site, try loading the "drivers" they have for your model.

Unless the instructions for installing a device tell you otherwise.......
(this ALWAYS applies to video adapters unless the drivers and software for the video adapter is already built into Windows...)
You DO NOT install drivers for a device while booting into Windows, if the software for the device has not been installed yet - when Windows detects a generic device or New Hardware while booting, you allow it to search for drivers, it doesn't find any, and it wants you to show it the location of the drivers - CANCEL that, continue on to the desktop, and install the software for the device using the proper installation from a CD or the proper installation file that you downloaded from the web.

If you DID install drivers that way, go to Control Panel - Classic View - Programs and Features and Un-install the software you installed, reboot, DO NOT install drivers while booting, and install the software the right way !

If you want to re-install video "drivers", un-install the existing "drivers" in Control Panel - Classic View - Programs and Features BEFORE you install the drivers again !

("drivers" = the software for video (and sound) always includes other associated software along with the actual drivers. )

It is a very good idea to DISABLE any resident module(s) of anti-malware software or third party firewalls (a part or parts than run all the time in the background looking for suspicious activity) that you have installed, BEFORE you install video "drivers" , otherwise the software may not install properly.

A common thing that can happen with ram, even ram that worked fine previously, is the ram has, or has developed, a poor connection in it's slot(s).
This usually happens a long time after the ram was installed, but it can happen with new ram, or after moving the computer case from one place to another, and I've had even new modules that needed to have their contacts cleaned.

See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:

For a laptop, or netbook, you must remove both its main battery and AC adapter before you do that.

For a brand name computer, see the Owner's or User's manual if you need to - how to remove or replace the ram is usually in that - it may already be in your installed programs. If you can't get into Windows, it may be on a disk that came with the computer, or you can go online and look at it or download it - it's in the downloads for your specific model.

For a generic desktop computer, see the mboard manual if you need to - how to remove or replace the ram is usually in that.

If your video adapter is on an actual card that installs in a slot, you probably have a desktop mboard, and you could try
- remove the AC power to the computer
- remove the card, wipe off it's contacts with a tissue or soft cloth, install it again, make sure it's all the way down in it's slot and secured properly. Some AGP and PCI-E x !6 slots have a sliding piece that locks down the inner end of the card's connector - you must move that before you remove the card, and you should slide it back when the card is installed again
- restore AC power to the computer. If the video card has a fan make sure that it spins, and does not make rattling or screeching noises when it does (most likely to be heard right after starting a cooled down computer).
