Nvida and Bad drivers

Problem with 8800gt and New drivers

I spent 2 days installing removing drivers to no avail. I did find one guy who thought that installing the 3D drivers overloaded the GPU and fried the card. This may be true my 8800gt worked fine for a few weeks. It still ran windows and the internet ok but couldn't play any games or it just caused total graphics lock after a few secs play.

I ended up buying a Radeon 6870, Nvidia has seen the last of my money thats the second time there cards have broken

I doubt a driver can overload a card and burn it out.

Start with a clean install of the OS and see what happens when you follow the card installation from manual.

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.

OFC the drivers can burn components out. It just the same as overclocking can burn them out if they instruct the GPU or other components to exceed its normal working parameters. It worked fine for a few weeks then failed.

Offer advice when you have some of worth other wise be silent

And you expect someone to help you with an attitude like that. You'll get lot's of silence now.

The drivers themselves cannot burn out the video chipset

If you were overclocking the 8800 GT, then it's quite possible you used settings that damaged the video chipset. You overclock beyond the settings the video chipset (or CPU) was originally set to at your own risk - no warranty covers that. If you want to overclock, there are plenty of web sites that tell you which settings you can use for the specific video chipset or CPU that won't damage it and are stable. Especially if you overclock a CPU, try to find a site that has settings for your video chipset or CPU when it's been installed on your specific mboard model, otherwise the settings may not be stable for your mboard.
In any case, allowing your video chipset to get too hot for whatever reason will damage it.


System requirements.

Geforce 8800 GT

Minimum of a 400 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 26 Amps.)

"Radeon 6870"

500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for AMD CrossFireX™ technology in dual mode)

What's the (max combined ouput) wattage capacity rating of your PS ?

Your power supply must have at least the minimum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video - video built into the mboard - IS NOT A CARD ! )
If that info is not in the ad for the video card, you can go to the video card maker's web site and look up the specs for the model - often under system requirements - the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don't find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings - in that case, add those ratings to determine the total +12v current capacity.

If you're a gamer...
In most if not all cases, the max capacity rating of the PS is an intermittent rating. It's recommended that you do not load your PS to any more that 80% of that rating if you are going to be using something that puts a constant load on it, such as playing a recent game for hours on end. In that case, you multiply the min capacity stated for the system with the particular video chipset on the card by 1.25 to find the min. capacity of the PS you should have.

I didnt over clock the 8800gt that was an example of how graphics cards can be damaged by giving it instructions to exceed its normal working parameters. It was suggested that loading the 3D drivers caused the damage as the 8800GT pre exist the technology. The person who suggested this based it on his experience updating lots of PC to win 7.

My post was more to offer a warning about 8800GT and 3D drivers. As I have already replaced it with a Radeon 6870 powered by Corsair CX 500

So ? Does your power supply have enough capacity for the Radeon card ?

There are lots of ways your 8800 GT video chipset could have been damaged that have nothing to do with the drivers used that would cause weird symptoms when you used whatever drivers.

Or - the 8800 GT card may have been defective but the effects of that didn't show up until you had used it for a while.

There HAVE been major problems with NVidia video or main chipsets being defective in the past, sometimes in very large numbers, and in many of those cases the symptoms didn't show up until you had used it for a while.

If you get weird video symptoms while booting the computer BEFORE the operating system loads, that cannot be caused by any software on the hard drive - that's a hardware problem.

"The person who suggested this based it on his experience updating lots of PC to win 7."

There's lots of incorrect information on the web.
If you find MANY so called experts are saying the same thing, then what he said MAY be valid.

The video drivers themselves have no overclocking ability. There may be a program included along with the actual drivers that allows you to do that, but that's not part of the actual drivers.

Video "drivers" downloads always include associated programs as well as the actual drivers

On the other hand, I know from experience that NVidia doesn't seem to care whether a particular drivers version works properly with all devices it was intended for, as long as most of them ( or Nvidia video chipsets - see below) , have no problems.

( AMD / ATI removes buggy driver versions from it's web site as soon as enough people report problems with it, and they have previous driver versions easily available.)

I have an older Asus mboard that has an NVidia main chipset. When it was brand new I installed an ATI AIW card on it (Radeon video plus TV tuner and related ATI chips and video and audio input capability).

The AIW card worked fine BEFORE the specific ATI drivers were loaded when the NVidia main chipset drivers had been loaded,

and it worked fine when the the specific ATI drivers HAD been loaded when the NVidia main chipset drivers had NOT been loaded,

and it worked fine when the drivers for both had been loaded in Windows Safe mode or Enable VGA mode,

but it DID NOT work fine when the drivers for both had been loaded and you loaded Windows normally.

I searched the web and found that (newest) NVidia main chipset drivers version and previous versions was / were known to clash with ATI's Catalyst software .

I un-installed Catalyst - no change in symptoms.

I loaded the ATI software from the CD that came with the card rather than the newest ones I had downloaded, Custom install, did not install Catalyst - no change in symptoms.

I un-installed all the ATI software, loaded Omega Radeon drivers instead (they didn't use Catalyst or a need a .Net Framework version like Catalyst does) - no change in symptoms.
(The Omega Radeon drivers use ATI software, some of which is slightly modified - tweaked , with the approval of ATI, but it's supported only by the Omega web site).

I loaded the NVidia main chipset drivers from the mboard CD rather than the newest drivers I had downloaded - no change in symptoms.

I tried de-selecting several things in the NVidia main chipset drivers installation rather than using the default Express or whatever installation for both driver versions - no change in symptoms.

I suppose I could have tried to find an older version of the NVidia main chipset drivers on the web (the Nvidia web site didn't have them at the time), but was so frustrated I bought another new mboard that had an AMD main chipset rather than a Nvidia one.

No problems with the same AIW card !

(The card had NOT been damaged by the NVidia main chipset drivers.)

I came to the conclusion, rightly or wrongly, that Nvidia didn't give a dxxx whether their main chipset drivers clashed with the software for an ATI video chipset card. They have been a bitter rival of ATI since before the company was called NVidia.

The symptoms included
- the computer would black screen and reboot for no apparent reason when you did certain things
- most of the time when it did that, the bios loaded default settings except for the time and time. A custom configuration was required, so that resulted in the bios not finding a bootable hard drive partition to boot from..The computer owner was disabled and could not reset the bios settings herself.
(She wanted a TV tuner on the computer because she found it difficult to use a remote for a regular TV - she could use Media Center in MCE 2005 with a TV tuner adapter quite easily.)

When I used a PCI video card, neither of those things ever happened (see below).

When I used another mboard with the same AIW card, power supply, cpu, ram, and drives, neither of those things ever happened (see below).

I got the AIW PCI-E X16 card for a clearance price (it had never been used before), but even so, it cost me, and was still worth, more than the Asus mboard with the NVidia main chipset. It was much cheaper to try another new mboard, rather than trying a Nvidia video chipset card and having to buy a decent TV tuner card as well. or a Nvidia combo card that had a decent TV tuner built into it, with the original Asus mboard.
I ordered the replacement mboard on the web, and installed a PCI card on the original mboard so that my friend could use her system until I was ready to swap mboards (she had an older PCI TV tuner card that I installed as well) and try the AIW card again - no problems with that video card (a different Radeon video chipset on it).
(I haven't tried a different PCI-E X16 video card with that mboard yet - I didn't have a spare one until recently - both the ones I could try have a Radeon video chipset.)
