Dell xps 420. Need upgrade advice please.

Hello recently the gfx card on my Dell Xps 420 decided to crash my system.

Repeatedly.

Gfx:8800gt
Psu: 375(underated I hear)

Firstly my games would crash and I could still hear sound and gameplay as well as other programmes running the background eg. ventrilo.
But now seeing as I cannot access desktop without the system freezing, I need a replacement gfx and possibly a psu?

Anyone with experience concerning the dell xps 420 able to help me?

What graphic/psu options are availiable to me concerning the dell xps 420s Mobo? I hear its not atx? So I am not sure what to do with it.


I have used the search function on but there seems to a sort of yes you can but then again the dell xps "apparently" only goes up to a 425 psu.

Any help is most appreciated.

Jacobite.
