Hello, the reason that I write this is that I have problems with my computer since I downgraded my Windows Vista Home Premium 32 to Windows XP Proffesional 32 with service pack 3.
Every time i try to play a game, my computer monitor is going to "Sleep Mode". When this happens i need to restart my computer serveral times to get it started again.
I've tryed to install drivers for my computer, but without luck.

But i still think that there is some drivers missing, because in "Device Manager" there are some yellow "question marks", but i dont know what is missing.
Here is a pic of my Device Manager:

Anyone got any ideas? Regards Zapman
