GFX Card Installation Problem

I just got a replacement card after my 6600gt went on the fritz, but I'm having a problem getting Windows to recognise this new card. It's a 7600gs.

In System>Hardware>Device Manager there is no Display Adapters icon, and when I go to Display Properties>Settings>Advanced there is no card recognised, no information about it at all. I'm currently running off stock at 1hz, I don't know what's wrong.

When I try to install the latest Forceware drivers, it says it can't find any hardware suitable for the drivers and cancels setup.

Any ideas here?
 
Restart your PC (with the 7600gs plugged in) and go into your BIOS.

When in there, check your primary video adaptor, and change it to AGP or PCI Express whatever your new card is in.

Not sure what your problem is but that is what I would do first.

7600 GS on AGP is quite new, have you tried those on the disk that came with the card? If it is PCI-E then I can only suggest making sure all your old drivers have been uninstalled 100% (perhaps trying driver cleaner).
 
The card is AGP.

The drivers on the CD say exactly the same thing.

Here's my settings in the BIOS, I must confess to not knowing much about it:

AGP Spread Spectrum [Disabled]
Graphics Aperture Size [64MB]
AGP Frequency [66MHZ]
Video RAM Cacheable [Disabled]
DDR Reference Voltage [2.6V]
AGP VDDQ Voltage [1.5V]
AGP 8X Support [Enabled]
AGP Fast Write Capability [Enabled]

Are these setting ok, or is there something that has to be changed? Any help is very much appreciated here.

The settings look ok to me.

you could try to disable AGP Fast Write Capability to see if that helps any.

No effect. :(

I think I should also just add, that the last time I booted up my machine just now, it said "Warning: CPU may have changed!" and it's gone down from being a 2400+ (Athlon) to 1800+ :confused: All I did was remove my DVD drive connection to make sure the gfx card was getting enough power from it's own direct line to the PSU, odd..
 
It appears your multiplier has downclocked from 15x 133 to 11.5 x 133.

BTW, are you overclocking because if you are try to Enable - AGP Spread Spectrum.

I just upped the multiplier again, I'm sure I didn't touch it beforehand though.

I'm not overclocking, but I enabled AGP Spread Spectrum just in case, but again, no effect. :(
 
Ok, some.... sort of... progress here.

I was looking in the Device Manager in Windows to see if there was anything I missed, and I noticed that under System Devices there was a caution mark over the option for Nvidia Nforce2 AGP to PCI Bridge (or something like that) so I updated the drivers for this.

Now an extra option has appeared under the category "Other Devices" called "Video Controller (VGA Compatible)".

However, trying to install the drivers onto this device, or installing the drivers from disk, is proving fruitless. Now I'm stuck again.
 
nForce 2 bridge? You have the motherboard chipset drivers installed right? Can download nForce driver package from nvidia website. Maybe when you removed drivers for old card you accidentally left the tick box checked for the nForce drivers too?
 
Aye I'm going to reinstall all the nforce drivers in a few minutes. But I just want to say....

Success! :)

Forced Windows to accept the drivers onto this unknown VGA device and it worked, apparently Windows couldn't verfiy that the gfx card was compatible with my hardware.. :/

Anyways, I should be able to sort it all out from here, thanks for the help guys. :)
 
It might be that cos the 7600 AGP is so new the drivers aren't quite up to scratch/updated everywhere they should be, which would explain the verification issues, just a guess tho :p

And Congrats on it working :D
