Yesterday I built a new PC (Windows 7 Home Premium 64 bit OS), installed the OS and Motherboard Drivers. I also performed all of the Windows Updates. I got a single BSOD which 'may' have occurred when the PC went into Sleep Mode. I then selected to never Sleep. The PC has been Stable both before and after the BSOD. I am currently testing the memory with MemTest 86 version 4.3.7. Several Passes already have been completed with no errors. I plan to let the Memory Testing continue for as much as 24 hours. WhoCrashed Home Edition Results: I guess that the safest thing to do would be a Clean Install of Windows. However, I would like to first know what is the cause of the problem. The problem may occur again after the Clean Install of Windows. I am suspicious of the software for the on-board NIC. The on-board NIC manufacturer will not let you install only the Driver. You have to also install their bloated software (Qualcomm Atheros Killer E2201 LAN chip). This may not be the problem at all, but I have a tendency to 'jump to conclusions'. Any tips or advice on where to go from here? What is the name of a recommended forum where you can upload Windows Minidump files for analysis? Thanks in Advance.
