PC Help, urgent replys appreciated.

Hi there,
I recently purchased a pc from a computer shop, custom built, and the graphics seem a tad blurry and when i play MOH:AA it freezes and i have to power cycle.
The problem is, i have a identical pc in the other room which is my brothers, and he has had no problems what so ever.
The computer guys have been trying to sort it for weeks now and still cant figure out the problem.
Downloaded latest drivers, changed motherboard, the lot, still cant work it!
Any ideas?
Using NVIDIA 6400 GS.
Tried playing with the internet connected and disconnected.

Moved by Hitman (Forum Moderator) from Technology Discussion: Please post in the correct forum next time, thanks. :)

The 6400 is just a crap card :(

Its always possible your 6400 could be faulty

Apart from that, any ideas?
The 6400 plays all the games i want to play fine :)

Maybe it's your version of the 6400 card.. Maybe it's faulty?

If you have time, put your brothers card into your PC and see how it goes.

It could also be your power supply, maybe it's faulty or is crap. Are the power supplies the same in both PC's?

Are you running the correct resolution for your monitor size, and are you running Vista or XP?

running correct resolution yes, xp.
resolution has nothing to do with it freezing tho
