Screen switches off while playing games

Hi, I was starting to play Portal but as soon as it loaded my screen switched off. This doesn't happen while playing Microsoft flight simulator 2004. Could someone please help I really want to play Portal!

Does your system meet the minimum requirements to play portal? If it does, once the game is installed have you checked the system settings for graphics display for best resolutions?

It does reach the minimum requirements to play:

Minimum Requirements:

1.7 GHz Intel Processor
518 MB Ram
NVIDIA GeForce3 128 MB or ATi Radeon 8500 128 MB

My System:
2.1 GHz AMD Duel Core M320
4 GB Ram
ATI Readon 4200 Series

I don't know much about ATI but is the 4200 series better, or at least, equal to the 8500? if not... there might be your answer.

Another one is corrupted drivers, perhaps you need a clean install of the latest drivers?

I don't know how you do a clean install of the drivers.

Thanks but it says "STEP 2. Reboot your PC and go into Safe Mode when your PC is rebooting, by tapping F8 during the black screen with ~4 or 5 lines of text which comes before the Windows loading screen, and then selecting 'Safe Mode' as the startup type, and 'Windows XP' as the Operating System." It says to use Windows XP. I use Windows 7? What do I do now?

Same steps just look at it as xp instead of 7 lol the fix is the same across the platform don't get confused follow the steps like you were if it was xp and it should come out the same
