DVD-rom may work only after restart

Forgot to mention that i have tried locating the "lower" and "upper" but they dont appear. I can locate HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
but there is no upper or lower.

As for killing explorer.exe, it made my screen useless with just my desktop background left and i had to reboot.

Thanks everyone for the advice. !@#$ Windows 7. What a horrible waste of time and money.

There is a good chance this will work - sorry i didnt see your post earlier i live in Australia :)

You may need to download and install the latest intel matrix storage manager software/driver because AHCI would be enabled in your bios, and what happens during installation of W7 is W7 installs the Intel driver, but for correct functionality you need to install the intel matrix storage manager after installation is complete if you dont it will cause the problems with your DVD DRIVE.

You will find it at the intel site - http://downloadcenter.intel.com/default.aspx
Select chipsets - desktop chipsets - select chipset (express 975)- skip OS - select drivers(10) - select intel(R) matrix storage manager 8.9.0.1023 - download and install.
There is a mix up with download site so you need to skip OS to get to it now - once there you will see it supports Windows 7.

Hers the latest ati drivers if you havent already installed them - http://game.amd.com/us-en/drivers_ca...indows-7-64bit
