I have asrock P4VM890 motherboard. I use SATA hard disk (SAMSUNG HD160JJ). In my computer was WINXP. Then I tried to install windows 7. My computer was to week for that system, so I decided to downgrade to WINXP again. But I couldn't. Something was wrong. I formated my hard disk, and then when windows should to install, my screen showed "A problem has been detected and windows has been shut down to prevent damage to your computer...".

I read some forums. Some people had same problem as mine. They solved this problem when they turned AHCI to IDE in BIOS. But in my BIOS there isn't this function.
Maybe, someone know what can I do to install WINXP? I think it's motherboard fault (BIOS).
