Ok bit of background on this problem. Had a sierra aircard 580 on this laptop previously without a single bsod/panic problem.

This is on a dv8210us with an AMD Turion 64 cpu. Unfortunately the cardbus chipset is the TI (which seems to of been notorious for these issues). I have already flashed my bios to the most recent one I could find on HP's website. Unfortunately it didn't do much good to fully resolve the bsod's I've been getting. Changed the usb driver to the generic/standard one from the NEC that was auto selected (helped some I get the bsod's less often, still getting the random panic/crashes however).

Not positive on exactly what is causing this at this point. Any useful help would be appreciated. Also note this laptop was just recently re-installed from scratch using HP's recovery disc system. Running XP Home edition SP2 on it also.

Recap: once I installed the Novatel Merlin S720 aircard (sprintpcs evdo wireless internet access), the laptop began randomly bsod'ing. I'm unsure exactly what the issue is now as I've read tons of different data on what can cause this anything from it being the card itself to the card drawing too much usb power, to all it needing is a bios update on the laptop (which I did already and didn't help a thing).

Basically i need this problem resolved asap fully with a viable solution. Keep in mind I do use USB 2.0 devices as well (external hdd's) so just disabling usb doing such workarounds isn't going to help anything.

EDIT: Also to note I did contact HP and they gave me the usual spiel trying to claim it was a compatability issue (as if I needed to call them to know that much). Seriously at a loss for why a bios update would not of resolved this as it seems to be something with power regulation. As there are times where I'm online fine with this card in and it doesn't act up at all then quite a few hours later when I think it was fixed finally bsod out of the blue (even if I'm not that active on the internet making the card do anything).

Also an additional note I have already tried un-install/reinstall of the drivers and the card. If whomever opts on helping on this I'm extremely grateful as I'd really like to get this issue resolved fully and not have this problem anymore. If anyone needs additional info such as minidumps or anything of the like just let me know (and obviously what path as I haven't had to do bsod diagnosing using them myself ever, typically I was able to find the issue without analyzing such files).
