Nvidia OFFICIAL Drivers

It is Data Execution Prevention. It is basically software (or hardware in the A64's case) that prevents the processor from executing potentially harmful code thereby preventing memory overflows. Sometimes however it prevents essential processes of a program from running in turn giving a blue screen.

It is a good idea just has some bugs to be worked out yet.

So far neary a BSOD for me In fact DEP works as advertised for me so far, it provides a message stating DEP has stopped a program to help protect my system and I have the option of letting it run or or not. This happened just yesterday during a Acrobat update.

Well, i am not happy at all with nVIDIA's drivers.

Now that i have disabled DEP, after a few normal reboots, i will get into Windows & my display will be 800x600, & some settings i changed with programs will be back to the way they were before i changed them.

It's as if the PC has crashed, yet i merely restarted.

I think i'm gonna switch back to the 61.77s , unless someone could guess why i am having these weird problems now.

Slide show frame rates and blurry textures?

Painkiller shows a significant performance gain over 61.77 for me.

(or hardware in the A64's case)

Intel too.

DEP is fine, it's the programs/drivers that need to be fixed.

hahah...for me when I had DEP on I couldn't access Search, User Accounts, and Services...which were all core windows services!! HAHA!!

Well damn. Any advice on what to do? I ran the Uninstall from the Add/Remove Programs and selected to only remove the display drivers. Reboot. Installed new drivers. Reboot. Changed the AA to 4x and the AF to 8x in the driver settings. Also changed to high quality. These are the same settings I used for both drivers (61's and 66's). Any other tweaks you or anyone else can suggest?

I didn't even try Far Cry or Doom3. Painkiller was so bad, it just didn't matter. Everyone seems to be making some gains, but me.

Driver cleaner.

Reinstalled 66.93's using driver cleaner first (followed instructions in the readme). Far Cry still ran fine. UT2004 had frames rates in the teens. Same with PainKiller and Doom3. I just don't get it. These drivers tank my 6800UOC.

66.93ownloaded,installed,tried ............rushed straight back to my old drivers.
I've got the very unfriendly blue screen...scary...
So, I think i'll stick with the good old 61.77 but maybe I'll give the 66.81 a try.

Actually, it's both. DEP is MS's term for both a software + hardware solution. The software part is (at least in part - there may be more) a set of re-compiled binaries for XP in SP2, equivalent in function to using Visual C's "/GS" (generate stack probes) compilier switch. The hardware solution is only currently provided by AMD64 CPUs, by their "NX" (no-execute) bit feature, which prevents execution of code from virtual-memory pages set as "NX", on a per-page (usually 4KB, but could be 4MB) basis.

An application-mode DEP exception will trigger something basically like a GPF, and tell you that the application has attempted an "illegal operation", executing code from a non-executable page, or a stack buffer overflow.

A kernel-mode DEP exception (which is what appears to be happening here), is basically like a BSOD, it triggers a system halt or restart. (If the video drivers themselves die, the system can't BSOD either, even in the case of a "normal", non-DEP-initiated system halt. The system will just freeze or reboot, in that case. I've been having that trouble myself recently, actually, although it has nothing to do with DEP or UT2K4.)
