This is getting pretty annoying now... Is there a freakin compatability issue with the 4850 and Vista? There have been several times (pictures below) when I doing something on the computer (most times playing a game) and the system crashes. when I reboot it tells me it's a VGA issue... I am frustrated because I have looked for updates for this VGA driver but there seems to be non, yet it crashes at times??? What can I do about this???

My second issue with this card is that the clock timings wont change when I overclock them. Here are the supposed factory clock speeds:Core clock 625MHz, Memory Clock 1986MHz

This is the default my card came with: 500 mhz GPU clock, and 993 memory clock

WHAT IS GOING ON??? I am going crazy trying to figure this out. When I try to overclock it with the catalyst tool it refers back to the original clock speeds and I have no idea why.

And finaly when I try to overclock with ATI tray tools if crashes OMFG???
Is this a hardware problem? or am I doing something wrong... contributions are very appreciated!
