Windows 7 Screen black install/Common problem can't get it fixed.

[beezm]

Alright guys. I guess I'll start with some system specs:

ECS Black A780GM-A rev.1.1 Mobo
AMD Phenom X4 9600 Agena 2.3Ghz
4GB G.Skill 2x2GB DDR2-1066
250GB Seagate SATA
AMD/ATi Radeon HD4850 512MB

I want to start with, this isn't a new build, I've successfully installed Windows 7 x64 Ultimate on this machine before. More than once in fact. I really don't remember having this problem the first time I installed Win7. Indeed I've tried reburning the image. But once again, I've installed from this same CD before. More than once.

Now when I get to the Win7 setup/install once it gets to Expanding Files (1%)... my monitor loses signal. Well some quick research brought me here and yes plenty of other people having this issue. My main search brought me to Link Removed that microsoft support link.
According to that it should fix the problem by connecting a second monitor. Well I've done this and no go. They both go out at the same time instead. Now what really confuses me is according to that link, my system is affected. Well why didn't it do this to me before

I haven't modified my gfx hardware since. I'm doing the USB drive thing now. But I really don't get why it didn't do this the last 3-4 times I've installed win7 on this system. My partitions are a little goofy I guess ? Could that have something to do with it ?

Thanks a bunch for any help.

UPDATE/EDIT:
Well now I'm having completely separate issues with this Autounnattend.xml file and my ati drivers on a usb drive. I'm just getting tossed a windows cannot calculate space error, after some research.. it looks like I have to set soem params in this file, but I have no idea what. I'm trying to get this installed to Disk 0 partition 2

It seems like you're facing some challenges with the installation process on your system. Let's address each of the issues you mentioned:

Monitor Signal Loss During Windows 7 Installation​

1. Monitor Signal Loss Issue:
   • The monitor losing signal during the Windows 7 installation process at the "Expanding Files (1%)" stage can be frustrating.
   • Trying to connect a second monitor as suggested didn't solve the problem for you. This could indicate a different underlying issue.
   • The fact that you've successfully installed Windows 7 on this system before without encountering this problem makes it even more puzzling.
   []Partition Configuration:
   • You mentioned that your partitions might be a bit unusual. While it's less likely that partition settings are causing the monitor signal loss, it's worth checking if there are any anomalies in your partition setup that might affect the installation process.

     Autounattend.xml File and ATI Drivers Issue​

   []Autounattend.xml Configuration:
   • The "windows cannot calculate space" error seems related to the Autounattend.xml file and potentially incorrect parameters set within it.
   • You need to ensure that the parameters in the Autounattend.xml file are correctly configured, especially if you're aiming to install Windows 7 on Disk 0 partition 2.

     Recommendations:​

   • Monitor Issue:
   • Try installing Windows 7 with minimal hardware connected (remove any unnecessary peripherals).
   • Check for any hardware changes or issues with the graphics card that might be causing the loss of signal.
   • Ensure that your BIOS settings are configured correctly for the installation.
   • Partition Issue:
   • Before making changes to the partitions, ensure you have backups of your important data.
   • You can use disk management tools to check and potentially modify your partition setup if needed.
   • Autounattend.xml Configuration:
   • Review the Autounattend.xml file and ensure that the parameters related to the installation drive are correctly set for Disk 0 partition 2. If you need further assistance with the Autounattend.xml file parameters or any other specifics, feel free to provide more details for a more targeted solution.
