Trouble with BSOD ironically after driver installation

Hi i just recently built a new pc everything was working fine up until i installed a webcam + driver , then the BSOD error started - They happen only when the desktop icons are loading after a few boots the system succesfully makes it through the icon loading and i can play games an so what eva no problems after that and no BSOD when its working ever, until i reboot again and then the BSOD appears and i reboot couple of times and it makes it through

this is the error message

PAGE_FAULT_IN_NONPAGED_AREA

0x00000050 (0xAD6D80F0, 0x00000000, 0x8052A8D8, 0x0000000)

thats what i see on the blue screen i have tested the ram each with each slot same problem still occurs have also removed graphics card and run it on intergrated graphics problem still occures and yes i have removed the webcam drivers and it from device manager, have also cleaned the registry countless times

BTW im running winXP SP2

 

So, this problem started after installing a web cam and it's drivers, correct? And even if the web cam is not connected, and even with the drivers uninstalled, you still get the BSOD errors? Very strange. I did find this at the Microsoft Knowledge Base:
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q310869
It's mainly about a scanner issue, but since web cams are very similar to scanners, the same issue may apply to your situation. I also found this:
http://msdn.microsoft.com/en-gb/library/ms793437.aspx
I was going to suggest booting to the recovery console and running chkdsk C: /r and it is suggested in that link also, so it may be worth a try. You might also try a system restore to a date right before the web cam was installed. Several other links and more info can be found here.
Scroll down a bit until you see the info for 0x00000050.

Good luck! I hope this helps!

 

i reinstalled windows and stayed clear of the webcam everything is back to normal now - thanks for the help
