Solved IRQL BSOD blues

Hi All,

Need some help with a IRQL not less or equl... BSOD.

1) No new hardware or software update except windows
2) Uninstalled both audio and video drivers - no effect
3) upgraded both audio and video drivers - no effect
4) ran memory test with no errors
5) runs perfect in safe mode
6) will BSOD after I try to log in with the same error each time

Basic Specs:
DFI Bloodiron P-35
e8400
Evga 9800 GX2
4 GB OCZ dominator ram (2x2gb)

PC has been very stable until the last week or two... I am attached the last 3 mini dump files in the hope someone can point me to the offending driver if that is what it is.

Thanks in advance!!!

It's this thing in all 3 dumps:

Image path: \SystemRoot\System32\Drivers\SRTSPL64.SYS
Image name: SRTSPL64.SYS
Timestamp: Fri Mar 21 04:12:28 2008 (47E29AFC)

Thank You!!!!!!!!!!!!!!!

Symantec Endpoint Protction ws the !@#$% that caused this BSOD. I have fixed it with a HOTFIX from Symantec which is available at the following location:

Problems accessing file shares on Windows Server 2008 64-bit running Symantec Endpoint Protection

Cheers!
