Computer freezes when playing games

[jkloispace]

Here's the thing, when I play games on the computer, after a few minutes until it freezes and becomes a buzzing sound, requires restart.
I've tried everything, graphics measure temperature, core, changing RAM slots, install the drivers, Direct X changed, still nothing. Hard disk has changed, changed RAM. Nothing yet.
I bought a new graphics NVIDIA GTX 460, and put a new power supply from the 550w Does anyone have a solution or to change the motherboard, everything but the game works!?

do you that much like the game ??

anyhow , check the game in different systems and if the same occures , it may be the game ? DVD problem ?

and if it works in other systems , that says the problem is in ur device ...

it may be the RAM , how much RAM do you have ? and what is your windows ? 64 or 32 ?
and how much min RAM the game requires ?

I have 2 GB of RAM. The problem is not just one game, but in all. From weakest to strongest. 64. Thanks for the replay.

Try updating your Nvdia drivers and updating direct x. Though upgrading to 4gb's of ram would benefit the machines performance. Also update windows 7 to the latest service pack if you haven't and all the updates. Updating sound drivers and such would also be good.

i think 2 gb is less if your system is 64bit
