My dvd-rom is working fine, but it doesn't auto-load. Recently i reinstalled my window xp because i installed a new motherboard. The old system didn't have this kind of problem but the new one did. Im frustrated sometimes because it stays there, when i put in my music cd or game. Is there anything or anyway i can correct this weird dvd-rom? cause i don't know where did i messed up? it didn't have this kind of problem before...

My comp spec:

Gigabyte Nforce 2 7-N400L
AMD athlon xp 1700
1 GB of ram DDR 400
Geforce 3 ti200
1 dvd rom and 1 cd burner
80GB harddrive (40*2)
