Where is the Nvidia folder in regedit? I can't find it. So I did a system restore and got the pc back to where it was before I started all of this.

After spending most of the day on this I'd decided to put back in the FX 5500 and ran into problems installing that driver. Getting the same error message ' The parameter is incorrect.' I used Driver Cleaner Pro. I went from a FX 5500 256 MB to a Geforce 6200 512 MB. I also have a problem installing the driver. They installed with no problems and away I was with my new card! I can't tell ya how relieved I was!Īfter 5 days of trying and hours of frustration, my new card is operating properly! Thanks a lot for your help! Once up, I tried installing the drivers again (I actually installed directX off the CD first). I ran drive scrubber, restarted my computer (so the uninstall could complete), then shut it down.Īfter that, I took out the old card, installed the new one and started up my computer again. (I had read in other forums that not even drive scrubber could delete the registry entries unless the permissions were changed). This actually worked for me! After I did the uninstall through add/remove programs, I went into regedit and changed the permissions in the Nvidia folder to full. Try driver cleaner, just get rid of the nvidia drivers, nVidia drivers are notorious/infamous for screwing up if not completely removed before installing new ones. Even the 175.16 errors 'The parameter is incorrect.'ĭo I just need to take this card back and forget it? The FX 5200 works just fine, I just wanted to upgrade to more dedicated memory. I just don't understand why the driver will NOT install. It is model # ISO 300 and is a 'Worldwide.' There is a large sticker on the side that has the following information:Īnd then there is a section for DC output that has each color wire and then numbers. I replaced the PSU a couple of years ago with a BestBuy branded PSU. The older driver I downloaded and tried was 175.16. Is there a sticker on the side of your PSU stating how many watts/amps it has on the 12V rail? Not usually a problem, depending on how many amps your PSU puts out on the 12V rail, the 6200 can draw up to 200W under full load(hungry old beasties) and usually sit around 120W(10amps) Also, i do believe your power supply is something like 250W, the 6200 calls for at least 300W. Okay, forget the 280 drivers, go back to at least the 197 series drivers.
