Monitor screen very dark after a few seconds

Specs: Windows 7
Hi Im running win 7 64 bit and today when I got home from work I turned on the pc and after a few seconds the screen went almost black, I can barely see the desktop in the background, if i do a 3 key reset the managment screen comes on but after a few seconds again goes dark! My friend had a similar problem with her laptop a few days ago, she said hers was ok after turning it off for 10 minutes but so far thats not worked for me, anyone have any ideas please??

Its a Dell inspiron desk top if that makes any difference?

it might be a power saving feature, many laptops dim the LCD to conserve power when not in active use. If active use doesn't "wake" the display you might consider changing the system's power plan to "high performance." This can be done through the control panel.

On a related note I have a Viewsonic monitor with adaptive contrast. When this mode is on, if the image on the majority of the screen is dark, the monitor adjusts the contrast, resulting in an even darker scenario. When I open up a brighter image (try google since it's mostly white) the screen becomes very bright. It's a technology with potential, but hasn't been perfected quite yet, at least not on my particular model.

Sorry I didnt make it clearer, my machine is a desktop not a laptop, it was a friend with a laptop who had the same issue, it turns out the backlight on my monitor had died and Ive had to replace the monitor, thanks anyway.
