Windows XP Pro.

I just installed a new video card in my Dell computer, a Radeon HD 5670. After I installed it, as my computer booted up, detecting new hardware, I went through the procedure for installing the drivers. I had the installation CD in the CD-Rom and thought I installed the drivers okay, but I did get an error message saying that it was not properly installed. When I checked Device manager, there was a yellow "?" for the cards, so I reinstalled it through device manager > reinstall drivers. It went smoothly but now I'm noticing that I'm experiencing strange behavior with my video. When I grab the scroller and move down the page, instead of moving as a solid sheet of text/images, the screen sort of shimmers, like it's repainting or something. I don't know how to describe it. I tried visiting the manufacturer's website for the latest drivers but the page with those drivers did not paste up: the 'loading' icon just kept spinning.

I'm wondering if there might be something that is interfering. I'm NOT a computer geek but wonder if either of these installed programs could be causing the problem.

I found them in add/remove programs.

ATI Display Drivers

NVIDIA

I think the ATI has something to do with AMD processor chips. My computer has an Intel Duo Processor. As for NVIDIA, I went to their website but didn't recognize any of the programs.

Anything else that might be causing my video card not to run smoothly?

Thanks.

First, go to http://support.amd.com/us/gpudownload/Pages/index.aspx and download drivers, save them to desktop.

Go to Add/remove programs/program manager and delete all ATI drivers/software.

Reboot, install the downloaded drivers. Select "custom install", or else it will install a bunch of crud. Install drivers and CCC. Reboot.

If it is still acting up, go into task manager and see what the CPU use is while on the internet. I have seen some older systems choke with IE8 and flash animations when too many background programs are chewing up CPU time.

Never use the driver disk for video cards as ATI releases new drivers every month, especially for the 5XXX series. I will likely end up getting a 5670 for my new HTPC build in a few weeks. Let us know how it works (if you are running Blu Ray through the
HDMI port on it, really let me know).

Good luck.

Double check your refresh rates if they are 60 Hertz you will see improved performance with 75 Hertz.

Thanks. I followed your advice and that fixed the problem. But I'm curious...why did I have that problem in the first place? I don't know why I couldn't access the HISdigital driver page.
