I built the system described in my profile for my brother. The DVD Rom drive does not show in the list of drives in My Computer or in Windows Explorer. When you enter the letter designation in explorer (e.g., "G:") it then recognizes it and reads fine.
My guess is that the usb ports, and the 15 in 1 card reader are causing conflicts.
Using Disk Management I reassigned the DVD from G: to Z: and rebooted but still the same. Not on the list of drives. Until I typed "Z:" in the explorer address bar, and then it pops on the list.
Is there some way I could determine if there is a conflict and then resolve it once and for all?
Any help would be appreciated.
