Scenario #1 : ECS GF8200A motherboard (nvidia chipset) with GeForce GT240 PCI-E video card, AMD Quadcore 9350e CPU, 4g memory, dual 500gb Western Digital SATA hard drives in RAID 1 configuration (using NVIDIA onboard raid). Windows 7, 32bit OS with UAC disabled. Upon installing Dr. Web antivirus, we get blue screen 'PAGE_FAULT_IN_NON_PAGED_AREA' # 0x00000050 as soon as the 'express scan' tries to begin starting during installation. The system then reboots and we can log into windows but will find that either the self protection or spider guard will have a red "X" on it. Uninstalling the product works, but once again when reinstalling the same process starts all over in an endless cycle, no other antivirus (tested Kaspersky and Symantec Endpoint Protection) or applications on this machine are having any issues.
Scenario #2 : ECS NFORCE9M-A motherboard (nvidia chipset) with GeForce 7100 PCI-E video card, AMD Dualcore X2 CPU, 2g memory, single 1tb Western Digital SATA hard drive (no raid). Windows 7 Professional, 32 bit OS with User Account Control (UAC) disabled. Upon installing Dr. Web the install completes, we reboot and get back into windows, all appears ok, UNTIL you double-click the 'Dr. Web Scanner' icon on the desktop to launch a scan - then blue screen, one of two, the traditional "PAGE_FAULT" 0x00000050 as listed in scenario #1 and sometimes a 'IRQL_NOT_LESS OR EQUAL'. Uninstallation of the Dr. Web corrects all problems. Once again, this system is stable with other A/V products and is having no lockups or blue screens with any other applications.
Scenario #3 : Intel 845 motherboard (intel chipset) with onboard Intel 845 graphics, Intel Dualcore Core2 CPU, 2gb memory, single 500gb Western Digital SATA hard drive (no raid). Windows 7 professional, 32 bit OS with User Account Control (UAC) disabled. Upon installing Dr. Web the install completes, we reboot and life is good... Then we upgrade the video to a 3rd party PNY PCI-E video card with nvidia chipset (7800 series) - install the latest drivers from nvidia (auto detected) and reboot. About 1/2 way through startup, blue screen of death (BSOD) 'PAGE_FAULT_IN_NON_PAGED_AREA', machine reboots and 1/2 way through again, same blue screen, we are now stuck in a reboot loop. It is resolved quickly by removing the nvidia pci-express video card and allowing the intel onboard video to take over...
There appears to be a huge conflict in systems containing EITHER a motherboard with nvidia chipsets OR video cards containing nvidia chipsets. In further testing, it *does not* appear to be the latest drivers from nvidia causing the issues either. On a completely fresh install of Win 7 32bit we still experience the PAGE_FAULT 0x00000050 upon install of Dr. Web, even before loading chipset drivers or any windowsupdates. Furthermore, we are *not*, so far, seeing this issue with Windows XP and nvidia, testing has been good on XP.
We are also noting that on systems not containing Nvidia chipset(s) - the product appears to work great with no real issues to report on Windows XP or Windows 7.
Dr. Web developers... Any ideas?? This is a huge conflict - Windows 7 with Nvidia - please help!!
