Would this Motherboard fit in this computer?

M3A78-EMH HDMI Motherboard fit in a Hp pavillion a839n?
I have not replaced anything as everything inside is still the same
Its a Windows XP (the Hp pav)
BTW IMA GAMER
i just wanan be able to play Cod4
Madden 08
COD MW 2

Would i need to buy a new tower?
Would the Processor fit into the motherboard?
Would the Hard Drive fit into the new motherboard?
Is the motherboard only for Vista?
Is the processor ok or should i upgrade to AMD 2.7ghz processor for 70 bucks?

anything else u need to add

 

that computer will never be able to run those games, my advice:

get a new computer.

it would take an absurd amount of upgrading to be able to play those games at an acceptable framerate, and i dont know why you would think a new motherboard would improve performance in games. games rely on your graphics card, processor, and RAM.

a good combo of those three would be as follows:

and anything between 2-4gb of ram, but since ram is so inexpensive these days just get 4.

i advise you put together your own computer, its not as hard as it seems.

 

Yea i have been looking at making my own computer
I have like 10 sticks of 2gb ram
I just don't like the idea of buying new Hard drive and using vista

 

Buy XP then.

 

you do realize that if you get a new motherboard you would have to reformat your hard drive...theres no way around it. also what makes you think you have to use vista? you can use any OS you want...

bottom line is you cant play those games without getting a new computer. it would be a waste to upgrade your current one.

 

Motherboard graphics wont help your gaming problem. I suggest you buy a discrete graphics card.

 

May i just ask..

Can you put multiple ram sticks into one pc e.g. 3 x 2gb sticks = 6gb

 

If the motherboard (Main part, with all of the chips and such) Has multiple DIMM slots (Ram slots)

 

just get a new computer all together go to a computer shop as you do not seem competent to build your own computer (no offense).
