Flashing screen

[Regallag the Perv]

My computer broke, so I had to nuke the hard drive, re-install windows and do some hardware stuff (but I didn't do anything to the graphics hardware or software).  Naturally, one of the first things I did was to re-install Skyrim.  I started a new game without any mods installed just to make sure it works, and sure enough there was a problem; The screen flashes sometimes, like a colored strobe light blocking my view of everything.  It doesn't happen all the time, just enough to be annoying with out rendering the game unplayable.  It seems to happen when the sky is visible and when using potions (that flashy effect that they give).  I turned off anti-aliasing and anisotropic filtering, but the problem persists.

 

Any help would be appreciated.

Yeah, I forgot about that.  The smoke in the loading screens can be bright neon green or purple (although truthfully I think that part of the glitch just looks really cool).

What GPU do you have? It could be drivers, or maybe (possibly) artifacts.

 

Could we get a picture of it, please? It would help a lot ruling out one or the other.

I tried to get screen shots but it hasn't worked, it won't show the flashes.  Attempts to get screen grabs of the weird color loading screens only show a blank black screen.

 

The only hardware difference between now and before is that I used to have 4 memory sticks and now I only have 3 (one of the slots was burning them out).

I managed to get a screenshot of the flash (ignore the blurriness, that's the drunk effect from RND):

I managed get a few more screenies:
