Nvidia 8600 GT not detected (Motherboard: nForce 630i)

nitebullet · 21 Dec 2011

Hi everyone.

Yesterday I was looking for a driver for my old webcam.
Therefore I installed a program named '' Driver Detective''.. However It did not do the job ( It seems like it' some sort of a scam based the research i've done about it)...As a result I've deleted it. As soon as I've done the work I wanted to do I had shut down.

Now here comes the real problem:

When I started pc, my monitor was showing a blank screen saying ''No signal input'', though I still could hear the GPU fan spinning at full speed. I could get the image back up again by connecting my monitor to my onboard card, but why is my onboard working instead of the 8600GT? I did not open the case or whatsoever. I've also noticed that on driver manager it's not showing the 8600GT, instead it's showing the onboard card (7100). I've disabled it by rightclicking and was hoping that it would show the 8600GT instead. But it didn't fix the issue. I've also tried to uninstall the drivers and reinstall it again (64-bit display driver and chipset), but no luck so far. Also I can't seem to find the option to disable the onboard card through bios.

This problem has never occured before, not until I installed ''Driver Detective'' crap.

Any solutions?

additional info:
Q6600 2.4ghz
W7 ultimate 64bit

Your best bet is to do a system restore to a point before you downloaded Driver Dedective (which is a scam). This will reset most of your software settings to exactly how there were before the problem began.

System Restore

EDIT: Also, if you tell us them model webcam, one of us might be able to find a driver for you.

@ petey: got my cam up and running now

One thing I know of that you can try to fix system restore is to open command prompt and type "chkdsk /r" without the quotes and then restart the computer. That might help.

Troubleshooting System Restore is not exactly my cup of tea, so I'm going to rally the troops and see if someone with some first hand knowledge in fixing it can help.

Hi nitebullet, check in the bios that onboard graphics has been disabled, programs like driver detective have the habit of messing with system files

Hello again. A friend pointed out to me that the Driver Detective software may have been bundled with some malware and it is a good idea to do a virus scan. What AV do you use? In addition to doing a scan with your regular anti-virius it is also recommended to do a scan with Malwarebytes free. Another thing that was suggested was using the system file checker. Please refer to the link below.

SFC /SCANNOW Command - System File Checker

SFC /SCANNOW : Run in Command Prompt at Boot

You should try the option two of the tutorial System Restore , too .

Onboard graphics will vary by BIOS provider. It should be in Onboard peripherals, Hardware or similar. PEG will be the PCIe slot if that is what you have.

none of these solution worked..ive now formatted my computer and installed a fresh w7 copy but the gfx card still remains undetected

i've also opened the case, took the gfx card out and put it in again but no luck..the card was placed well and the fan is spinning all the time
