|Well how about you provide some details.|
Like what brand/make/model is the computer and it's motherboard?
What brand & model is the existing ram?
What are the specifications of the extra ram you inserted?
What were the "some words" ?
Honestly how do you expect us to diagnose your problem when the only information you give is "'Windows 7, Doesn't work, Some words"
Here's a starting point. Take the new ram back out.
See if the system will boot with just the old RAM.
If so visit www.crucial.com and let them scan your system to see what ram is compatible with your motherboard. It is almost certain the new ram you inserted is not compatible. Hopefully you have not damaged the system.
