Your CPU is overheating.

Try and get into the BIOS and increase the fan speed & any aother fan on the system. Don't increase the temperature range, as this will damage the system.

You won't be able to sort out the software problem until the system is running within the hardware limits.

You can also run a office fan to help get the system to cool while making the changes in the BIOS.

Run diagnostics on the harddrive. if possible reseat the Hard drive, i.e take it out and put it back again. and then try installing the OS. remember you have to boot from the laptop to install OS. Hope you are doing it correctly

"Base System Device" is your card reader, I had the same problem. If you dont use it jst disable the device, otherwise the drivers should be on your alienware Master CD, if not get a tech support guy to send 'em to you.

Is what I would do is go to  start>run>type cmd> reformat C:/ and this will clear out your hd. Then just reinstall ur choice of OS. Or you can just inseart the OS disk and it will give u the option to reformat that way. Hope this helps.

Turn off the Notebook remve all the peripherials, Remove battery and disconnect AC Adapter and then press and hold down power button for thirty seconds.
After 30 Seconds connect Battery and Power supply as soon as you tun on the Notebook keep on hitting F10 Notebook will show BIOS then F9 Notebook will show Load Set-up Default than Hit yes and Hit F10 again it will show save Exit and chnages now that show Fix the Problem
If not than use Philip Screw Driver take out optical drive and put it back in Reinstall CD/DVD Drive drivers using Device Manager .
