Try updating your video drivers. Don't use the ones from windows update since manufacturers have released official win 7 drivers (vista ones work too) but nvidia has actual win 7 versions available on their site and ati should too

Also make sure your video card is plugged in snug. A loose connection can cause this as well. Also it could be related to sleep/hibernate so try changing your power settings to high performance if they aren't already. Hope this helps
sunkast, it sounds to me like it IS an issue with the video card. It almost sounds like it might be overheating. I would try the simple first: take the side panel off of the PC, load a program that is somewhat graphically demanding, and make sure the fan is spinning up and providing sufficient airflow. Also, ensure that the heatsink/fan assembly is clean and not caked with dust.
That seems like maybe the graphics drivers are corrupted.
Try going into the BIOS (setup) when you first boot up...if the screen stays up then it shows that the default drivers are working as they are suppose to... when the screen shows black after windows boots shows that the installed drivers may be faulty or may be a conflict with something else starting up as well.
Try booting to the start page to use the "Safe Mode " settings to boot windows. This will only allow certain drivers to install and run. Navigate to the Device manager and see if there are some conflicts or bad drivers .
When you first start your computer toggle the F8 key and keep doing it till the computer shows the start-up page. If you see the windows booting window it didn't work and you need to try again!
Very old thread and long since been resolved
