I don't know much about computers and what graphics cards are the best and statistics a good computer should have. I have always played games on my laptop and have never had issues with running the games and staying connected, i just cant play on uber graphic settings. However, my current laptop is starting to show signs that its life is coming to an end. Every now and then it will freeze and i will have to force a restart, and things just load significantly slower than they did a few months ago. Now i am looking into getting a new affordable gaming laptop but would like some help/advice on what to go for.

As stated, i dont know much about computer statistics so i put as much as i could find out from my control panel.
My current laptop:
MSI A6000 - 029US 16" Widescreen Notebook Computer With Intel Core 2 Duo Processor T6600
Processor Intel Core 2 Duo CPU T6600 at 2.20GHz
Memory RAM 4.00 GB
Graphics NVIDIA GeForce 8200M G
Gaming graphics 1663 MB Total available graphics memory
Primary hard disk 60GB Free - 115GB Total

Please suggest ways to fix the issues with my current laptop if it is still decent or recommend a gaming laptop to replace.

Thank you.
