Execute disable bit

[Rubycon]

Anyone ever see this before?

With execute disable bit turned ON in the bios, I would get random freezes on certain webpages. With it disabled the freezes went away. This did not matter if the system was overclocked or not. The strange thing is it was not a BSOD or hard freeze as there was still disk activity and the cpu monitor on my keyboard (G15-II) would occasionally change. But the keyboard/mouse input was totally ignored.

Additionally, all traffic coming in is screened for malicious code, etc.

NX would most likely cause application crashes (not OS crashes) if it were acting up, not freezes.

NX is for AMD whereas XD is for Intel.

DEP is pretty useless IMO as long as the software is secure & up to date.

I've had DEP crash several of my programs (along with installers) and had to manually allow them through windows. Doesn't give an option to turn off DEP globally, and still uses software DEP even if the hardware one is disabled in the bios.
Seriously though, crashing the program? That's barely better than letting it do its harm, especially when it's often crashing programs that are accessing the hardware directly. Do not want my FPGA programmer crashing, k? Do not want my cd burning program crashing, k? Vista, why do you suck?

Doesn't give an option to turn off DEP globally ..... Vista, why do you suck?

My Computer->Properties->Advanced Settings->Advanced->Performance->Data Execution Protection
...and it's default OFF.

Not for me.
My options are:
Turn on DEP for essential Windows programs and services only (many programs still crash because they use said services)
Turn on DEP for all programs and services except those I select (which at least lets me give them a per software pass)

Actually I found this was not the problem at all - the POS 3870X2 does not get along with my DFI FPUTX48 board at all. More testing needed. The 9800GXT OC seems to be working fine.

Back to DEP - it seems in the past we had some trouble with some *old* programs not running because of it. The installer would run and finish but the system was never modified and it turned out that DEP was the culprit.
