Blue Screen

[1Cane]

 The middle of last week I replaced my 6850 with a new 3gb 7950. Everything worked fine untill this weekend  ,while over tank town I would get large swings in frame rate and even screen freeze. I decreased the enviromental slider with modest or no results. After getting 3 blue sreens I redown loaded amd drivers.  This morning after down load my primary bomber had selected skin and remaining drone had default skin,also whiskey compass was black and gauge above do not exceed was black.
 If I redown-load game over existing game will I see any differnce?
 If latest attempt at driver download gives no result what is recommmended action to take?

The 7950 is going to need about 80W more power from the power supply than the 6850 is.  What power supply does the computer have in it?  Take care here.  If you have managed to overload the power supply, you do risk damaging the entire computer system the longer you try to run it.

Also note, you should purge the old video card drivers when changing video cards or you can get some problematic results.

I have an 800watt power supply, specs call for 500watt minimum.Will check and delete old drivers. Is that neccessary sinse they are same brand"HIS"?
 Thank you fou your help.

What 800W power supply is it (model/brand)?

The same brand, but different families/GPU's.  Different set of programming parameters needed in the registry.  ATI and NVidia do a really bad job of cleaning up after themselves, so it is quite possible for parameters from the old video card to impact the new card.

My current power supply is extreme gear  model XG P800. My original set up was 2 6850's in cross -fire and there power requirements was 65watts. Eventually I plan on changing power supply to a 800 watt modular.
 Went to training area and magnetic compass and instrument above don't exceed speeds placard are still black. Is this a common bug or will a new game download fix that?

Nothing about your problem is common.  It is pretty unique to your computer.  The power supply could be going bad.  It is not the best quality supply available.

It could be driver related, but for it to suddenly change usually means something else actually changed to cause it.  Drivers are not normally suspect for this.  Hardware usually cause it.

I uninstalled amd and then reinstalled it with driver up dates . The last two days have had no problems.
