I just upgraded from Windows XP SP2 to Vista Home Premium 32 bit. Everything is running smooth, but when I restart (or start) my PC, it shuts down while booting on the progress bar screen. I get the Blue Screen of Death for about 1.5 seconds, enough to see "PFN_List_Corrupt" - it then reboots, hangs on a black screen for about 1 minute. Windows Vista loads and states it has recovered from an "unexpected shutdown" with the following details: Problem Event Name: BlueScreen OS Version: 6.0.6000.2.0.0.768.3 Locale ID: 1033 BCCode: 4e BCP1: 0000009A BCP2: 0003E329 BCP3: 00000006 BCP4: 00000002 OS Version: 6_0_6000 Service Pack: 0_0 Product: 768_1 Files that will help....

I have tried contacting Dell and Microsoft with no help. Please point me in the right direction - any help would be APPRECIATED!!!!! This is my first post, please let me know if this is the wrong place or if I need to check elsewhere. THANK YOU.
