driver / hardware combination bad?

[TheWaffle]

I have a dell inspiron 531. running windows vista
My device manager says that the integrated graphics card is a nvidia geforce 6150se nforce 430
The driver i installed was from the nvidia website I downloaded geforce 6 series driver.
Is this correct?
I continually get bsod's that say session_has_valid_pool_on_exit
Also the computer will sometimes inexplicably lock up and then blue light -> i believe it shows hard drive usage
on the case is solid blue.
is this possible motherboard or videocard failure. I checked the power supply with a tester and the hard drive with gwscan and the ram with memtest86 and windows memory diagnostic all passed.

laptop drivers should be obtained from the website of the computer manufacturer. Go to the Dell website, enter your service tag number, and download and install all appropriate drivers. Are there any yellow or red symbols in device manager?

It's a desktop actually

I installed the wrong network driver.
And the right one.
There was a yellow symbol saying missing hardware so I right clicked and uninstalled.

Sorry.

1) What is new or different since the last time everything worked properly (ie, new hw, new sw, virus, error, etc)?

2) WHEN do you get the bsod's (when you are doing something specific or at random times)?

3) Download BlueScreenView:
http://www.nirsoft.net/utils/blue_screen_view.html
unzip downloaded file and double click on BlueScreenView.exe to run the program.
when scanning is done, go to EDIT - Select All
Go to FILE - SAVE Selected Items, and save the report as BSOD.txt
Open BSOD.txt in Notepad, copy all of the content, and paste it into your next reply

I get blue screens when I log off. I looked up my error message and it says that either there is a bug in Windows's dlls( 2 of them I don't rember which) or the video card ain't dumping all its memory.
I have bluescreen view on hirens boot cd so in the next day or so I'll upload a report.  I run Microsoft Secuirty Essentials and I scan with super anti spyware weekly. The only thing the turns up are tracking cookies.

Dell's are finicky about drivers...you should only install them from their site using your Service tag #.

Check out a free program called whocrashed.
It will explain your blue screen errors in English and often offer solutions. It should tell you which dll files/drivers are causing the problem and what hardware they are associated with.
As others have mentioned, it's probably a driver issue.  I've found video drivers are usually the culprit, especially in laptops.

The video card that my device manager says i have is not one of the ones listed on dells web site

[patio]

So it's an addon card then ? ?
