Replacing a [Semi] Broken HD 7850 with GTX 770 today, questions about both..

post #1 of 2
Thread Starter 
I'm receiving a new EVGA GTX 770 ACX Superclocked 2GB GPU today, replacing a kind of broken SAPPHIRE Radeon HD 7850 2GB, and I have some questions about both of them.

As far as replacing my current GPU goes, should I just uninstall Catalyst and then replace the 7850, or would I have to use some type of driver cleaner to completely remove it to encounter no problems? I read somewhere that CCC doesn't interact with anything if an NVIDIA GPU is installed, so should I really bother uninstalling it?

Also, the problem with my current 7850, I literally have a SATA cable put in the middle of FAN #2 to keep it from spinning. Reason being, if I allow it to run, once the RPM goes beyond about 30%, the card will start to vibrate extremely hard and produce an extremely loud rattling sound, and it gets quieter once fan speed goes extremely high, but once it slows down again, it gets louder and never goes away, so I don't understand it. I asked one person this question before, and they asked if I was able to replace the fan on the card, which I didn't know was possible rolleyes.gif But, I did see some replacement SAPPHIRE DUAL-X 85mm and 75mm fans on ebay going for about $15-$40(1 fan or 2 fans).

Thing is, I'd think it was the fan if it weren't for the extremely loud rattling sound the card makes(I can even feel the vibrations in my case), and the fact that I can't visibly see the fan running into anything, so, any advice with that? Also if I remember correctly(I can't test right now because I'm not home) I think slightly lifting the card up with my hand fixed the rattling noise, but that was it.

Make sure to run the uninstaller through the Program and Feature option in Windows Control Panel. Once that is done, do not restart and run Display Driver Uninstaller which can be grabbed from: http://www.wagnardmobile.com/DDU/

Once you open the program, it'll ask you if you want to let it restart in safe mode, which you should say yes to. Then follow the instruction it gives you once booted in safe mode and choose the option that applies to you.

NOTE: This is what I do when I want to install new drivers or a new graphic card. The extra step with DDU is completely optional, as the AMD Uninstall Wizard is sufficient enough.
