Black Screen After Closing Certain Programs

The only problem I have is that when I open or close certain programs I get an unavoidable 'black screen'. IE: When I get done watching some Death Note in Windows Media Center (full screen) and I decide to close it, occasionally it will close and just go blank. My monitor doesn't detect that it's been turned off, or that there's a problem.

So I'll do what a lot of people do, and ALT-CTRL-DEL once or twice to try and bring up that screen. No luck. The only time I can retrieve everything and save my data before shutting off my computer is if I have an unfinished word document and when I press my power button the screen comes back on and viola! I see windows again! It then asks me if I want to save my work, click cancel, I can resume my Windows 7 enjoyment.

Well, because I press the power button and Windows wants to shut down, it closes out of some services and other programs, so I'm limited (barely, but limited) to what I can do.

It is not only WMC that causes this. I play Combat Arms in full screen, and occasionally when the program opens (into it's full-screenness) it will black screen (and I can still hear the music, so the computer isn't crashing) or when I exit the game. For a bit I thought it was just when I play stuff in full-screen and my video card gives out.

So I open Game Maker, and I attempt to make a game every now and then. I save my work, throw my project into a test play, and everything works out. It begins in windowed, and so I don't screw anything up, I leave it that way. Well, I came here because that was the last thing I did. Close out of a windowed game that probably took barely, if any, video ram (I know it takes some, but old computers' on-board VGA adapters would have no problem running the program I made.) and I get 'black screen' after closing that.

Out of being piss off'd (yes. piss off'd.) I go to the ATI website and download the latest 7/Vista drivers for my Radeon X800 video card. Got the drivers, nothing special happened. Still get an occasional black screen. Got one of the forms of the Catalyst driver thing (I don't know what they are, so I just install them) and still nothing. I know that there is a sticky in this forum for the drivers, and I already have the drivers linked here.

So I tried the 32 bit link (getting catalyst stuff,) and I'm presented with the first download link being for 64-bit computers only. Why is it in the 32-bit page? I even look at the URL, and somewhere up there is says .../vista-32/sumin'... or something along those lines. So what the heck? Downloaded it. Now in its installation 7 keeps telling me "This program has stopped working," "This program has stopped working" all throughout the installation process.
