BSOD when playing or browsing while downloading (0x000000d1)

Hello everyone,

I have been facing this BSOD ever since I built my computer. It used to occur once a week. Now it occurs more than once per week. I noticed that it always happen when I am doing something "heavy" while downloading something on Steam or uTorrent. By "heavy" I mean playing video games or browsing Chrome with multiple tabs and watching YouTube.

The following BSOD information were obtained from BlueScreenView
Dump file: 062515-17565-01.dmp
Bug Check Code: 0x000000d1
Parameter 1: 00000000`00000331
Parameter 2: 00000000`00000002
Parameter 3: 00000000`00000001
Parameter 4: fffff880`078fa76e
Caused By Driver: RTL8192cu.sys
Caused By Address: RTL8192cu.sys+8c76e
File Description: Realtek RTL8192C USB NDIS Driver
Product Name: Realtek RTL8192C Wireless USB 2.0 Adapter
Company: Realtek Semiconductor Corporation
File Version: 1006.0.0614.2010 built by: WinDDK
Processor: x64

Based on other threads and solutions from other websites, I have done the following:-
  • Updating BIOS
  • Updated all drivers, including my wireless adapter.
  • Reinstalled windows
  • Ran a hard drive check and a "MemTest". No issues
  • Uninstalled and reinstalled my wireless adapter driver

My system specs are all available in my profile.

Based on your posting instructions, I have attached the file to this post. I have also attached more information from BlueScreenView.

Any help would be greatly appreciated.

Thank you

It is ENCORE ENUWI-2XN4x Wireless USB Adapter (RTL8192CU) that is causing the BSOD.

Thank you for your kind reply.

I honestly thought I updated it already. Looks like the one I installed from ENCORE website is outdated.

I have applied what you suggested. I will give this a week or two to see if the problem is permanently solved. I will mark this thread as solved during that time.

Thank you very much for your help.

BSOD when downloading torrent, 0x000000d1
My Windows 7 laptop had gone BSOD for FOUR times and what I clearly saw when the system is dumping files is NETSYS.IO. The BSOD only started when I tried to download torrents through qtorrent so for me it seems that the program is the culprit, can't verify it though. Can someone help me?
