Brought A New Computer But All Games Crash

I fixed the problem i hope, i played one game ,that would normally crash after minutes, for hours its cool :grinthumb. i performed the following steps.

1. I took out my graphics and sound cards and inserted them in different slots within the machine.

2. this prompted a reinstall of both cards which i installed the sound and graphics driver ( leadtek and nvidia).

3.Within the Nvida settings i enabled the manager which gave me loads of setting i didnt change any.

now the game i have been trying to play since i brought it seems to work :haha:

Thanks for all the help and i hope the help in this forum helps others who have problems like me cheers guys and girls .
