In the rare eventuality that you get a Black Screen while upgrading to or installing Windows 7, you can try and see if any of the following troubleshooting steps help you.
The reasons for getting a black screen during the upgrade could me many. It could be a hardware problem, a driver problem or multiple video output issue.
First, please see if you meet the Hardware requirements for Windows 7.
If you meet them, you can try and see if any one of these help you:
– Restart your PC in safe mode (F8) and select Enable low-resolution 640×480 video option.
– The video output may have switched to an alternate port, when the driver was re-installed during online configuration . So please check for multiple video ports on your computer.
– Please also check for display output during BIOS POST. If the POST logo or text is not being displayed on-screen then the issue could be with the hardware.
– Boot the computer in safe mode by pressing F8 on restart. You may receive a message, on restart, that Windows could not complete the installation. Open command prompt, type devmgmt.msc and hit enter to open the Device Manager. Here disable Display Adapter. On restart, the installation should complete OK. Do remember to update the Display Adapter settings again, later.
– If you have a second monitor, unplug it, from your graphic card and see if it helps.
– If your video card has two DVI outputs, try plugging the monitor into the one you’re not currently using.
– Maybe your BIOS is old and you need to flash upgrade it.
Hope something helps.
