Random BSODs in Windows 7 Home Premium x64 which sometimes happensright after I log in to windows, and sometimes not for a few hours within turning on my computer.
Laptop model: IdeaPad Y550P (324156U)
The bluescreens can be avoided by booting into Safe Mode with Networking, which leads me to believe it is a software or driver issue. I've run the windows memory test utility, and it has found no problems with my RAM in its standard test.
Here are the details of the BSOD, copied from the windows crash recovery dialog.
I'd analyze the memory dump myself, but I lack the tools and they're pretty difficult to set up.
Problem Event Name: BlueScreen
OS Version: 6.1.7600.2.0.0.768.3
Locale ID: 1033
Additional information about the problem:
OS Version: 6_1_7600
Service Pack: 0_0
After combing through memory dumps and checking things on Microsoft TechNet, it would appear that my particular blue screen problem was caused by the Zone Alarm firewall.
Remember, this only applies to Windows 7 x64, bluescreen in the kernel module NETIO.SYS. Error code 0x7f (UNEXPECTED KERNEL MODE TRAP), 0x8 (Double fault)
After uninstalling ZoneAlarm, so far I haven't had any more blue screens. I recommend Comodo Internet Security instead.
