IRQL not less or equal NDIS.SYS

Hello all: Running a 2006 vintage Compaq Presario C502CA with Celeron M440, 1.86 GHz, 1.5 GB ram. Originally came with Vista Home Basic 32bit, I installed Win8 preview in July 2012 & it ran fine without issue. Did the Win8Pro upgrade a couple weeks ago & all semms well except that when I try to establish an internet connection, it crashes & reboots [no BSOD].

Here's the CrashMe output:

Crash Dump Analysis

Crash dump directory: C:\WINDOWS\Minidump

Crash dumps are enabled on your computer.

On Fri 2013-01-25 8:26:55 AM GMT your computer crashed
crash dump file: C:\WINDOWS\Minidump\012513-15506-01.dmp
This was probably caused by the following module: ndis.sys (ndis+0x2EDF8)
Bugcheck code: 0xD1 (0x1D, 0x2, 0x0, 0xFFFFFFFF87E35DF8)
file path: C:\WINDOWS\system32\drivers\ndis.sys
product: Microsoft® Windows® Operating System
company: Microsoft Corporation
description: NDIS 6.30 driver
Bug check description: This indicates that a kernel-mode driver attempted to access pageable memory at a process IRQL that was too high.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in a standard Microsoft module. Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system that cannot be identified at this time.

Here's the LAN driver:

Driver Name : Rtnicxp.sys

Version : 6.109.530.2008
Company : Realtek Semiconductor Corporation
Product Name : Realtek 10/100 NIC Family all in one NDIS Driver

File Attributes : A
Service Name : RTL8023xp
Service Display Name: @netrtl32.inf,%Rtlnicxp.Service.DispName%;Realtek 10/100 NIC Family NDIS x86 Driver

Upon the advice of HP support, Win Defender & firewall have been disabled, no other anti-malware is installed. HP advises that the latest driver for the Realtek chip is included in Win 8Pro, so I am at a loss.

Can someone help with this?
