Hello Members,

A PC based on one of AMD's current chip sets can give you the ideal combination of performance and affordability -- whether you pair a next-gen AM3+ Bulldozer with a no-holds-barred enthusiast motherboard, combine a fast-and-fun FM1 CPU with a budget board to make a gaming and overclocking monster that won't kill your finances, or find some happy medium with one of the many tried-and-true AM3 combos. AMD processors continue to benefit the most from motherboards that optimize power and temperature handling, whether you're taking advantage of AMD's well-known overclocking capabilities or not. In all cases, there are plenty of motherboard choices to nail down the exact list of features that you need and want most, and we're more than happy to share our choices with you.

you can search on Google for better results.

You did not mention brand and other specifications of the laptop. You should enter the brand name of your laptop in google and it will show you its mother board specifications. However, I would recommend you to buy a new laptop asap. The repaired system would hardly be the same as it used be in past.
