When I installed Windows 7 on my Dell D620 it was all fine until a couple of days later most times when I either shut down or suspend (by closing the lid). When I unsuspend or startup the computer, there is often a completely blank screen (can't see post screen or anything), and restarting doesn't help.
I've found that I can eventually bring it back up again by suspending and unsuspending a few times, but obviously this is not ideal.
Has anyone else experienced this? I think it is a driver issue, that somehow the driver is putting the video card into a certain mode that it forgets how to get it back out of.
Any ideas on a better solution than my switching off and on business?
Edit: Turns out that the video card had burned out! IT managed to get me a new mainboard sorted for me.
