Pixels follow cursor with Nvidia drivers on Geforce 4 1

[JJ1]

Dear All,

I have a PC with an "Abit Geforce 4 Ti4200 AGP(8x)" graphics card. When I boot Windows, I see the following problems:

1. Splash screen has a few stray black pixels over the Windows logo.
2. The user login screen then has vertcal stripes of black dots.
3. The mouse cursor has about 15-20 black pixels following it (no virus or spyware).
4. After around 10 minutes, the screen starts to refresh every 5 seconds.
5. After around 20 mins, a blue screen of death appears complaining of an infinite loop with "framebuf.dll" being the culprit.

The only solution is to remove the Nvidia drivers. After doing this and rebooting, I have no problems. However, I don't like to lose the performance of the card.

I have tried various versions of the drivers from the Nvidia website, but to no avail.

I also tried reinstalling Windows, but this hasn't helped either.

Finally, I tried different monitors (DVI and Analog ports) and reseating the card in the AGP slot - no success.

I now believe this must be a hardware fault. But, how come it works well when there are no Nvidia drivers installed?

Does anyone else think this is a hardware fault?

Your advice would be greatly appreciated.

Many thanks,

James.

P.S. My spec is:

Windows XP (sp1a), DirectX 9b, 512Mb RAM, Abit Siluro, Formac Gallery DVI Flatpanel, Geforce4 Ti4200-AGP(8x), Abit Mobo. (i.e. nothing unusual)

Could be a Driver conflict, there is a facility within the Windows XP i would like you to run, let me know what resukts you come up with.

If you could run these with the driver installed that would be appreciaed.

Firstly - when you open the properties of the video card does windows recognise a conoflict, if it doesnt then it will say 'this device is working properly'.

Secondly - do you know if the driver is digitaly signed by microsoft?

Third and final - Open up you display properties, settings, advanced, and find the hardware acceleration section it may be listed in the troublshoot section. turn down the hardware acceleration see if this makes any improvments.

If you fear that it may be a hardwrae falt i would speack to the nvidea support desk. although from your description it sounds un-likly it may be worth a go.

The driver may enable parts of the hardware to enhance the performance and it is these bits that are cuasing the problem.

Let me know how you get on.

1. No conflict
2. Yes it is. I believe all the release versions of Nvidia drivers are signed (don't quote me on this though).
3. Done this and rebooted, but it's hasn't helped unfortunately.

I also put the card in another machine and got the same problem, so I think a hardware fault is pretty conclusive although 13 months after purchase isn't a great time for it!

I've sent a couple of mails to Abit (manufacturer) and Dabs.com (reseller) but I'm not sure when the warranty expires.

Thanks for the suggestions.

Regards,

James.

I know that all products have a limited warenty but i know here in the UK if you are willing to put up a fight you will be able to get an exchange.

Under the consumer rights act resellers are obliged to exchange all goods that fail before a time where it is deemed acceptable by the consumer. i would say that considering all IT equipment as an industry standard gets up graded every 36 months 13 months is not an acceptable amount of time for it to last!

Just give the supplier loads of beef! make sure all contact is in writting! sure you will be able to convince them!

Well,if no nvidia drivers are installed and you are using a generic video driver from windows,none of the extra features of the card are being handled in hardware,they are being handled with the software renderer. More then likely the card is damaged. try to get it replaced from the cards manufacturer. Try it in another pc to be sure it's the card,but it sounds like a heat issue with the gpu.
