I am trying to install Windows 8 Pro Upgrade via the download method on an older PC (07-08). It is a Dell Dimension E521 but it has been upgraded with a 3.0 Ghz Dual Core AMD Processor, 120 GB SSD, and 4 GB of RAM. The Windows 8 upgrade assistant did not detect any issues or concerns with upgrading other than I don't have DVD software installed.

The system install Windows 8 but on the first boot, corrupt graphics are present. Eventually, the monitor will go into sleep mode and then roll back to Windows 7 Pro X64 which runs fine.

I wouldn't be upset over not being able to install Windows 8, but I already paid for the software since I thought there would be no issues upgrading.

The Graphics card in the system is the Geforce 7300LE and it has the latest NVidia drivers for Windows 7 loaded.

I saw this solution which is similar to my problem: Corrupt graphics during Windows 8 installation

However, I have downloaded Windows 8 and I am not sure how to go about modifying the install that resides somewhere on the hard drive.

Thanks in advance for any assistance.

Update I tried to install OEM driver from Dell, but they only have drivers for Vista x64. This is not compatible with my current setup. I am currently running Nvidia Geforce 306.97 WHQL which lists the 7300 LE as a supported device.

Update 2 I uninstalled the Nvidia drivers and cleaned them out, the system installed the WDDM drivers. I attempted to upgrade once again with the same end result.

I did notice that the link on my desktop allows me to create installation media. Is this something I need to pursue?

When you downloaded, the Upgrade Assistant would have given you an option to create installation media (USB or DVD ISO). If you didn't select that, how are you re-running setup? From a link on the desktop? – Karan Nov 8 '12 at 20:37
Uninstall the nvidia driver before you upgrade. – Moab Nov 8 '12 at 21:13
Hi and thanks for your responses. Karan: I am am not given an option for installation media. I am re-running the setup from the link on the desktop. Moab: I will give that a try, but I don't think it will work, the first time I tried to upgrade I did not have the NVidia drivers, it was a fresh Win 7 install to upgrade to 8. I thought that maybe I needed to upgrade the drivers before the install so I did that and I got the same error/result. – Andy Nov 8 '12 at 22:21
