Windows 7: BSODs with BCCode 50, various drivers but always ntoskrnl.exe+7cc40

BSODs with BCCode 50, various drivers but always ntoskrnl.exe+7cc40

Very frequents BSODs, mostly BCCode 50 but also BCCode 19 in about a 2 to 1 ratio, various "caused by" addresses, but "crash address" always ntoskrnl.exe+7cc40 as viewed with BlueScreenView.
FIRST thing I want to know, given that of maybe 50 BSODs, all have the same "crash address" is my presumption that this provides no information relevant and revelatory in my situation correct? Perhaps all BSODs with BCCode 50, 19, and 3b terminate with the same "crash address."
SECOND thing I want to know is which column in the BlueScreenView may contain information that I can begin to do something about?

I searched on some keywords in this forum and hit upon several similar posts, but enough different that I believe I could benefit from replies unique to those two questions above.

BTW, because I read somewhere that RAM could be involved in cases of BCCode 50, I have run the extended RAM pre-boot assessment a couple of times, and PC Check of memory with lots of walking this-and-that, and ran the whole suite of checks with all "passed."

Here are the files mentioned in the instructions regarding BSOD posting. I hope that it gives a helping person a clue that would get me out of the very frequent BSODs

Looking through the results of the diagnostic "Perfmon" output suggested in the "BSOD posting instructions" I see Symptom:[IMG]res://wdc.dll/error.gif[/IMG]
tv_ConfigMgrErr43



and the offending device:
this device is PCI\VEN_9710-DEV_9990-SUBSYS_4000A000-REV_00\4-B439320-0-06E0.

I presume this is something on a card inserted into a PCI slot only because of the letters "PCI"
I have opened Device Manager and have up till the present moment failed to see an entry for such a device, but of course I do not actually know how to look for it. Googling on PCI\VEN_9710 gives me lots of hits, but I have no reason at this time to trust what are for me unknown sites that offer downloads.

Both crashes blame Windows drivers so it's either hardware or a 3rd party driver causing the crashes

EDIT: Stop using CCLeaner. It deletes the minidumps we need to figure out what's going on.

Code:
nvlddmkm.sys Sun Sep 27 20:12:06 2009 (4ABFFF56)
Update your video card - NVIDIA DRIVERS 295.73 WHQL

Enable driver verifier - Driver Verifier - Enable and Disable

Code:
Device	PNP_Device_ID	Error_Code	
Standard OpenHCD USB Host Controller	PCI\VEN_9710&DEV_9990&SUBSYS_4000A000&REV_00\4&B439320&0&06E0	43

Are you having any problems with USB devices not being recognized by the computer?


Run these three hard drive tests
1. Hard drive scan usings SeaTools - SeaTools for Windows | Seagate - Both long and short tests
2. Disk Check
3. SFC /SCANNOW Command - System File Checker
