My first (three) Vista Blue screens

[JayFR]

Edit: Sorry, i didn't see the BSOD Subboard. Please move it there.

Hello. I am new to Windows Vista. I just bought a Vaio FW21E and after only one day the first bluescreen appeared. And this was not the last one, in the last few days i got three of them. I analyzed the crash dumps but i don't know what to do with the results so I will post them here and hope, that you can help me.
I have a Vista SP1, Intel Core 2 Duo P8400 @ 2.26Ghz

The Crash Dump results are:

MULTIPLE_IRP_COMPLETE_REQUESTS (44)
A driver has requested that an IRP be completed (IoCompleteRequest()), but
the packet has already been completed. This is a tough bug to find because
the easiest case, a driver actually attempted to complete its own packet
twice, is generally not what happened. Rather, two separate drivers each
believe that they own the packet, and each attempts to complete it. The
first actually works, and the second fails. Tracking down which drivers
in the system actually did this is difficult, generally because the trails
of the first driver have been covered by the second. However, the driver
stack for the current request can be found by examining the DeviceObject
fields in each of the stack locations.
Arguments:
Arg1: 8f3a5220, Address of the IRP
Arg2: 00001d00
Arg3: 00000000
Arg4: 00000000

The thing that stands out the most in your posting of your dump information is avguard.exe which is part of AntiVir antivirus. I would go to their forums and see what they say about Vista and this driver.
