BSOD after Video Card Upgrade

I just tried to do a video card upgrade, from a nVIDIA 8800 320MB to an ATI 4770 512MB and now I am getting a Blue Screen "attempt to execute non-executable memory" error in Windows XP 32 bit. Happens very early in first 5 min of normal boot. Does not seem to be happening in safe mode.

Memory wise I had Two 2-GB corsair sticks, DDR2-800 in there but only 2.7 GB was addressed.

I thought maybe the 4770 using more memory was the problem so I tried switching out the Corsair 4GB with an older pair of two 1GB sticks of OCZ that I had. Doesn't seemed to have helped.

I think maybe its a driver issue, even though I uninstalled the nVIDIA display and Phyxs drivers before installing the 4770(and used driver cleaner, etc.). I did not uninstall the nVIDIA chipset drivers, I might try that later though.


Any Suggestions?
 
Sounds like a driver issue, but since you already uninstalled it, I don't know. I'd probably try your other drivers.

You should also put your other card back in and see if it boots up that way, just to make sure nothing happened. (static or something.)

Don't do that. You didn't change chipsets.

It may be a heat or power issue, but I'd dry different drivers first.
