I have a PCI express geforce7600GT & it has had it.Whenever I boot up my PC it says out of range on the monitor. It is trying to show it in 100hz even tho it is set for 60. I have a old monitor that only displays upto 75hz. The only way I can get around this is unplugging my Geforce7600 & going back to the crappy onboard graphics nvidia6150.
I changed the motherboard battery incase it was not saving the settings but that hasn't solved it so do I buy a decent monitor that will display over 100hz as mine is a rubbish old CRT or get a new graphics card ? I'm sure it will be out of warranty as I have had it about 18months.
Anyone any idea how I can get around this ? it just started happening last night.Does it sound like the graphics card to you ? Seems stupid chucking it if works on a decent monitor or is it just on the way out ?
Anyone any ideas?
Thanks Neil

PS not sure how rFactor will run on the rubbish onboard graphics will have a look later may not be able to race yet this week.

In my control panel I have Nvidia control panel which allows me to "manage custom resolutons" under the display management tab. I havent used it but I assume it does what it says and would allow you to force a lower refresh rate.
If not you may have to try running rFactor in Dx7at a low res. with display setting turned right down and visible cars turned down to as few as you can stand, I think mine is set to 8 to be on the safe side at the back of a 30 car grid. You'll find the Dx panel in rFactor config in your root directory, double click it and away you go.
Fingers crossed.

I had this problem once. Plugged in a TV which then was autodetected while the other graphics board was still plugged in. Ran in dual mode, and changed the settings to make the monitor follow the TV, not the other way around, got picture on the monitor, changed the resolution and settings on the monitor I think, and got the TV as slave. Whola monitor working. Disabled the TV and changed the monitor to the correct resolution.

Might not remember it entirely correct, but you get the idea.

Gonna play around & see if I can get my proper card working again & lock the refresh rate somehow.

I think I've fixed it (fingers crossed) I went into the nvidia control panel & created a custom setting of 60hz.
Then looked on thre net & it said to lock the refresh rate go to start button then search & type in DXdiag.exe
It takes you to your directX utility programme & in it you can override the settings & set it to 60hz.
I then put my card back in & it booted straight up . I have rebooted it again & it worked so hopefully it is fine now.
Why on earth it suddenly started playing up after all this time I have no idea !

Think this might have something to do with drivers failing, but it might also be hardware related.

It's still ok at the minute would it be graphics card drivers that are failing ?

I'm no expert, but if you dare, you could try and remove the drivers and reinstall the newest ones. But sadly I can't remember why that happened to me. It might also be motherboard drivers, so the solution is probably to do a google search and/or un-/reinstall drivers. But I don't recommend uninstalling motherboard drivers as my experiance tells me that might block some system components until you reinstall windows.

My PC has started playing up again so had to take my 7600GT out & go with the crappy onboard ..gulp..
Had a quick go on rFactor & had to turn down all the detail & think it may run but will see it looks horrible.I will log on to the server before next weeks race & see if it is useable.
I have emailed nvidia to see if they have any solutions if not it may be a new card at some point or new monitor either way I need some spare cash first !
