Windows 7 Doesn't Install

i bought Windows 7 some time ago but I havent got it working and one of my friends said that this is the best place for help. Thats what usually happens: I put in Windows 7 dvd and make a restart to boot it. When my computer sais press any key to boot i press enter and everything goes like it should. It loads files and then comes that screen: I can move the mouse but nothing happens. I'm not sure for how long i have to wait but i waited about 10 min and nothing happens and then i pressed the restart key. Then my computer dosent go past Verifying DMI pool data and i have to close my computer and then XP runs again. I tryed all this again but the result was the same and then i thought i install Windows 7 from my deskop. I used autorun, pressed install and everything went very smoothly. It installed everything withhout any problems until it had to do a restart after installing. After restart im back to that blue screen what i showed above only that a small line was moving at the bottom. Nothing happens and because it dosent move i restart my computer then it dosent go past Verifying DMI pool data until i shut my computed down and then i get a message that installed failed and xp will be restored. Im seriously out of ideas and Microsoft isnt interested of helping me to. They said contact my motherboard maker what i did and they said Windows 7 works and ask Microsoft
