Hey i have this problem:
My build-in dvd drive is missing from “my computer” (i have a Acer lap top)
with XP.
When i turn on the laptop,the Acer screen comes up forced me to go to set up.And every time i must go exit-discarding changes to enter the windows.
I tried to do the registry trick that i saw in some articles
[Start] [Run] [Regedit]
Registry Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class
Key Name: {4D36E965-E325-11CE-BFC1-08002BE10318}
Value Data: [Delete All Value Data from UpperFilters and LowerFilters]

but there wasn't any UpperFilters or LowerFilters there.
Any ideas?
Thanks in advance.
