Alienware 14 2013 laptop:

Went into msconfig and inadvertently changed numbers referring to "number of processors" and possibly something to do with amount of RAM memory. Now OS won't boot, I fear it's because I changed acceptable RAM to almost nothing and now it can't hold the OS?

Added to the problem, I put a windows 7 disc in the drive hoping I could recover from the disc. Now even in safe mode computer is not booting and I can't eject the disc (tried fn-f4).

Also system restore is not working.

Any thoughts?
