Who has had a PCI-DIO-32HS card fail, ever?

Question

I've looked through the forum somewhat and I've found little concerning the card itself failing.  For instance, I found something about the card failing due to driving it with a TTL high before it was powered, but that was about it as far as actual death of the card.  Hence, I'm wondering if others besides myself, and therefore my design using the PCI-DIO-32HS, have killed or had the death of a PCI-DIO-32HS DAQ card and what was determined to be the root cause in your case(s).
Also, by chance, did your card's death also take down the PC such that it wouldn't POST (Power On Self Test) until the card was removed?
Thank you all.

First, the issue has not been resolved yet. I still have boards dying. At $1500 a pop, this issue needs to be resolved.
I was mistaken about two things said earlier: 1) The G card has now failed; therefore, the recovery was a fluke, and 2) I thought 8.x was installed in the design's PC, but as it turns out it has been 9.x. (The version numbers are tough to remember. Sorry. I think it's 9.1.7.) Is there a known issue with that one also?
What I really want to know is why the original board I returned to NI failed. I want to know specifically what slot contacts are holding up the PC, keeping it from performing its POST? I don't want to hear any more suggestions for installing version x.y.z. without also having a specific reason for why it should work. These cards are too expensive. There's something very wrong with this design such that I can't keep the DAQ card alive using Traditional DAQ software that has run for years. The system works until (it seems) you think the problem's been resolved, and then whammo! An esoteric error number in a window is thrown up. (It's not just one error. The error can change as you try in vain to avoid cycling power as the only way out of the now dead software.) You can't run the software past a button click due to the error window, but yet the PC itself works fine...unless you cycle the power: NO POST.
What on earth in this design could be killing these cards? The PCI slot was tested via substitution with a video card and there was no issue found. I just can't keep the DAQ card alive. Help! Trying version x.y.z of the driver is not a good enough solution. Running software should not just out of the blue blow up a DAQ card and cripple the PC only at power-up. Rather, there should be an error, some incompatibility indication before the card is dead. Frying a $1.5K card...eventually...is not how you find the source of an incompatibility issue. Like I said, HELP!
I'm suspecting the software is creating a bus contention somehow which doesn't end in an error but, rather, an internally shorted IC, where I'm guessing it's the large NI ASIC just above the card edge due to the considerably noticeable heat generated while the PC tries to POST, a short that is undetectable except that the software stops working, but nevertheless a short that won't let the PC continue its POST if power is removed and then reapplied to the PC. It's like the software has had a "sacrifice(PCI-DIO-32HS, legacy_sw);" function embedded into it that only gets called under certain circumstances, circumstances that involve the power-up sequence of a PC. Help!
