Geforce 6600 256 powerpack! Golden Edition

[Baski]

Hello.

I am having some trubble with my graphic card (title) and i dont know what it is.
Problem: I cant play BF2, matrix, and so on with the highest "performance, attitude" (my English is really bad, i´m from Sweden).
And when a bought it, i was told it would work really good with almost the highest "performance" (almost the best graphic in other words), but when a try playing bf2 with those settings (aah thats the word) my computer shuts off, reboots.
And when i´m trying with the lowest settings, there is a lot of bugs and the graphic is really bad.

Anyone else with the same problem?

I have updated BIO`s, downloaded the newest drivers and so on.
