Hello, I have some BSOD problems in Windows Vista Ultimate x86 that have gotten worst after installing a nod32 trial version. I had a few until then, but seemed random and didn't manage to find out the cause. Most of them are 0x50: PAGE_FAULT_IN_NONPAGED_AREA errors. After installing nod32 and starting scan the system BSOD again, and did the same every time i tried to scan. BSOD when running the sfc /scannow command in cmd. Uninstalled nod32 in safe mode(uninstalling also BSOD normally), then sfc /scannow ran ok. Tried installing nod32 again, same problem, BSOD after starting scan. Uninstalled, but system keeps crashing about once an hour. Crashed while trying to install kaspersky. I've been running with no anti-virus for about 2 weeks when decided to try nod32. System specs are: Dell Dimension XPS 630 Intel Core 2 Quad Core Extreme (3.00Ghz) NVIDIA nForce 650i SLI 4 GB DDR2 667 MHz 2 X 640 GB HDD SATA RAID 2 X NVIDIA GeForce 9800 GT Crative SB X-Fi All drivers are up to date, downloaded from Dell website except for chipset and video downloaded from Nvidia, latest updates. I can provide any additional info requested. Thank you.
