Hello.
Thanks, you don’t know how much I love you right now. Kept reading everything but my motherboard but what I got was do I was clueless. I found a different part number on this site which I tried and now my laptop works perfect again.
Looks like I bought the first laptop motherboard for the wrong processor but when I found the right one, it couldn’t of been a more smooth operation.
You made me and my kids happy again now they could play their favorite notebook games.
Thank you for the compliments and I’m so glad you were able to get your laptop back up and running. Kids without video games is like corn flakes without the milk lol. Your story is a example of why I do what I do on this site because I once was a beginner… and I couldn’t believe how confusing they were along with how much I spent buying the wrong motherboard time after time.
Hope everything goes smooth for you in the future.
Thanks again,
Justin
