I was able to find your specs here: http://www.findlaptopdriver.com/msi-2a9c-specs/

Here's the ideal RAM for your system: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231492
And the ideal CPU: http://www.amazon.com/dp/B003HIXGVW/

I would definitely recommend against buying that CPU new though, this is much more reasonable: http://www.ebay.com/itm/Intel-Core-i5-680-SLBTM-MALAY-CPU-2-5-GT-s-3-6-GHz-LGA-1156-Processor-/161865726484?hash=item25aff2fa14:g:1GwAAOSw9mFWKEdb

If you want the rationales behind these parts, feel free to ask.

i try a lot of rams with this spect 4gb but all reboot my system but i dont try 2gbs rams

Hmmm, after digging further through Google I found that that's an HP OEM motherboard, and that it actually does support 4GB sticks. Sounds like you need to update your BIOS for compatibility. Problem is I couldn't find any such BIOS update on HP's website :/ If you want to try for 16GB of RAM, here's this: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231442 That RAM's almost the same as the kit I linked earlier, but with double the capacity.

OK, got it. I did some more research on the RAM I suggested, and it turns out it won't automatically run at faster response times unless you're able to manually set the timings in the BIOS, which given that you're using an HP computer, is very very unlikely. That means that you'll be just fine running 3 more sticks of DDR3-1333 that aren't anything special: http://www.newegg.com/Product/Product.aspx?Item=N82E16820226096
