OS: Windows 7 Home Premium x64 (original) Manufacturer: Dell Model: Inspiron 15r (N5010) RAM: 6GB CPU: Intel i5 M460 2.53 GHz RAM: 6GB Video card: Intel HD Graphics Sound card: IDT High Definition Audio HD: Intel 5 series 6 Port SATA AHCI Controller, 500 GB Motherboard: Dell Inspiron N5010 A12 Ethernet: Realtek RTL8103T Ethernet Controller Wireless card: Mini WLAN half size DW1501 Wireless-N/Broadcom Virtual Wireless Adapter Antivirus: McAfee (before formatting), Avira Antivir (after formatting) Firewall: Zonealarm Hardware age: 2 months OEM: Yes, before formatting. After, I downloaded from the internet (I have my unique serial key) Age of reinstallation: 1 day Problem: BSOD only when connecting to a specific, unprotected wireless network in a matter of minutes (may vary between 1 minute to 15 minutes). What I have tried: Before formatting: tried some free registry correctors and restoring system. After formatting, I updated the BIOS, and reinstalled/updated the following drivers: chipset, video, sata, ethernet and wlan. Minidump files from 3 BSODs and 3 CPU-Z prints are attached. Safe mode with network: no BSOD (tested for 1 hour). Description: For 2 months since I got this laptop I had no problems using wired and wifi networks. But just when I brought my laptop to mom's place, where I will be living for 2 months, I'm getting BSOD everytime I try to connect to the wifi network here. The last 2 BSODs occurred 1 minute after I connected to the wifi network, but the others time varied. When my wifi adapter is on, but not connected to any network, everything works fine. I get no BSOD or any other errors. Before formatting, and after the firsts BSODs I've got a file called mfewfpk.sys corrupted, that seems to be related to McAfee antivirus. No viruses were detected by it and Malware Bytes Antimalware. As I couldn't find any solution, I formatted everything, but the problem still occurs. Other laptops and computers connected to the wifi network, each with different OS (like the one I'm using, which is WinXP Home Edition SP2), work fine. What should I do now?
