I'm having some problems getting the PC to recognise the new graphics card (Nvidia GeForce GT 610)
My specs are:
MESH Tower with AMD Phenom 9850 Quad processor
Windows Vista 64-bit SP2
ASUS M2N68-VM motherboard, AMD Socket AM2+
Motherboard chipset nVIDIA GeForce 7050 PV/ nVIDIA nForce 630a
integrated graphics is Nvidia GeForce series 7 Shader model 3.0 DirectX9 graphics processor.

I lost the red colour from the PC to the display. The display and the cables all checked out as good. So not a cable or monitor problem. I then tried my existing PCI express graphics card (ATI Radeon HD4350) and it wouldn't display but was listed in the display hardware, but I don't know if this ever worked properly. So I thought I needed to replace the graphics card, the Nvidia GeForce GT 610. Still no red colour nor is the new card recognised.

I found and loaded the latest Nvidia graphics software (306.23) and my red colour is back but I can still only use the integrated card. Please any suggestions?

Regards,
Ken

Thanks for the prompt response. I had already deleted all the ATi/AMD software and uninstalled the old card. Following your post, I cleaned out the nVidia software, removed the new card and re-booted with no card. I then tried the install procedure again and it still can't see the new graphics card. Tried updating the software still no joy. Some older posts mention taking the battery out to reset the BIOS, is that worth trying or a red herring?

Is there any way to test the PCI Express slot?

Removed the CMOS and when I re-booted I had to set the date and time - no problem. It didn't fix the problem with the graphics card but now had a whole batch of other problems. After about two days I now have the system stable again but when I put a video disk into my HD DVD player the whole thing just hangs. If I select explorer for that drive it hangs. The device manager reads "This device is working properly. Windows did not start a related device driver. To learn more, click the Driver tab and then click Driver Details."

No matter what I doit just doesn't update any device driver for the drive. The other CD/DVD drive works fine and yet I get the same message as above. If I try and play a dvd on the CD/DVD drive it works, I swap it over to the HD DVD drive, system hangs and the the other DVD drive won't function. The system will now not shutdown or restart! I have to do a hard shutdown.

This all went very badly wrong after removing the CMOS - never again

Problem was the PCI-E slot on the motherboard (card not recognised) no longer functioning plus some issue with the on-board graphics card connection (losing red), probably some sort of dry joint and too difficult to repair.

Thanks,
