back on and everythings fine except my cd drive has decided to start playing
up and being stubbon,i put the cd in and it lights up on the small window on
the side but doesnt read it,instead it comes back with the message of windows
has loaded the drivers but cant find the hardware device code 40,(something
like that)ive tried device manager and that gives me a yellow icon next to
the drive,ive also tried microsofts mr fixit but that comes back more or less

Windows cannot access this hardware because its service key information in
the registry is missing or recorded incorrectly. (Code 40)
Recommended resolution

Information in the registry's service subkey for the driver is invalid.
Reinstall the drivers for this device.

Uninstall and reinstall the driver

Uninstall the driver from Device Manager, and then scan for new hardware to
install the driver again.

You may be prompted to provide the path of the driver. Windows may have the
driver built-in, or may still have the driver files installed from the last
time that you set up the device. However, sometimes, it will open the New
Hardware Wizard which may ask for the driver. If you are asked for the
driver and you do not have it, you can try to download the latest driver
from the hardware vendor's Web site.
On the device Properties dialog box, click the Driver tab, and then click
Uninstall. Follow the instructions.
Restart your computer.
Open Device Manager, click Action, and then click Scan for hardware changes.
Follow the instructions.
