Upgrade from Radeon 4870 to a gtx560 ti now I have problems...

[superman_legend]

Hello, I just bought a gtx 560 ti as upgrade from the radeon 4870 512mb. I unistalled drivers like it said on AMD website for windows 7

http://support.amd.c...icsDrivers.aspx

I installed the gtx 560 ti. I then installed the drivers off the disk that came with card. I noticed that I had gained a lot of space on my hardrive about 20gb atleast, probably from uninstalling AMD drivers, but when trying to play games I would get freezes, or crashes after a while. Then I noticed steam couldn't install a redistributable C++ and I got a error saying no space in d drive. Then I noticed system apps like microsoft word, notepad, etc wouldn't respond when trying to open or crash shortly after opening. So I'm guessing the hidden part of my harddrive which holds the os data got corrupted somehow. I've heard people having problems when switching nvidia to Ati & vice-versa so I tried to make sure I uninstall drivers so I wouldn't run into any. Unfortunately I have, when I rebooted now I get a disk read error occurred press ctrl+alt+del. I had this happen once before after installing the card but I was able to get back in after multiple tries. Now it seems I'm stuck but I might be able to get back in.

Please give me advice on where to go from here. Also I had thought about buying a new harddrive, but if there's a way to fix the one I got I would like too. Furthermore, if I do have to start from scratch on a new harddrive what do I need to do for this not to happen again and what did I do wrong? This motherboard also has ATI integrated graphics which I'm pretty sure I disabled when I installed the Radeon 4870 about 2 years ago.

Please no advice about upgrading other areas of my pc etc. I know what kind of system I got and its fine for now.

Thanks

AMD Phenom X4 @1.8ghz (its better than you think, but will still upgrade soon)
8gb Crucial DDR2 Ram

Try system restore. Then get your drivers from nVidia. Never install the drivers that are on the disk (I know it seems counter intuitive, but they are usually old drivers).

I'm not actually blaming the old drivers for your problem, but something got screwed in either the uninstall of the old drivers or the indtall of the new ones. Hopefully system restore works for you. It'll make it really easy.

"AMD Phenom X4 @1.8ghz (its better than you think, but will still upgrade soon)"

it would have to be way better than what I am thinking. I bet you would not even get half of what that gtx560 ti can do in many cases with a cpu that slow.

See that's exactly what I was talking about. My cpu never goes past 50% no matter what game I'm running. When doing regular stuff it doesn't go past 5% usage. I was planning on upgrading Nov. 1 though.

But back to topic please.

I was scared to system restore because of ati drivers. So I should system restore to right before installing disk drivers or could I go back to before I installed card then uninstall ati drivers which I know everything was working correctly?

Download driversweeper and get rid of all AMD and Nvidia drivers.
Make sure you have the latest direct x installed.
Install the latest Nvidia driver package.
Make sure the integrated AMD graphics are off in the bios.

Go back to before you uninstalled the ATi drivers.
Remove them if still there then restart.
Driver sweeper and a registry clean using CCleaner would be helpful.
Restart again then install the latest NVidia drivers.
One more restart and you should be good to go.

Try safe mode and driver sweeper? Unless you can't even do that, then:

1. plug the Radeon back in
2. F8 during boot and load last known working configuration (or similar)
3. uninstall drivers, reboot
4. F8 during boot and safe mode
5. driver sweeper (from guru3D)
6. plug back the GeForce.
7. boot and install latest nVidia drivers from nvidia.com

Plus, have to agree with toyota... that Phenom, is it the Phenom X4 9100e one? You are killing your performance with such a slow CPU, really... Even the HD4870 was crying for much more... Try to upgrade it ASAP.

Worst case if none of the above are working you will want to boot off of your Windows CD, enter the recovery console and try to restore Windows itself to an original copy.

AMD drivers are not even close to being 20 GB. Something else was been removed from your system (and it sounds like a lot!) which has hosed everything else.

If you’re getting disk read errors it sounds like your HD may be dying. Use a utility to scan it for errors.

Sorry, I swear I already responded to this. I must be losing my mind. Go back to before you uninstalled the ATI drivers. Back to where you know the system was operating correctly.

Also, I'd be careful exactly what you remove. You have more AMD hardware than just the 4870. You wouldn't want to remove drivers for your other components by accident.

It sounds like your system power saving options are enabled. Go to Start -> control panel -> power options. Choose either the high performance mode, or click on "change plan settings" for your current plan, then click change advanced settings, scroll down to processor power management, expand that setting, and make sure "maximum power state" is set to 100%. This will allow your PC to use all of it's processing power when needed.
