Build by ati card X700pro 256 mb Black out problem. When gaming

[DDC]

Build by ati card X700pro 256 mb vivo Black out problem.
the problem is that my crt turn off by it self and i cant get it back
on when gaming. I suspect that my new video card is over heating and
turn off by it self or something.

I'm using the 5.6 version of driver on a a7nx8x-x nf2 mobo
+xp 2600 333

Also i'm experiencing strange boot up noise like the video card fan
going to hell and then it stop and i never hear it again even in hard
gaming...

What could it be.
