Hello, I have a Toshiba laptop and just installed windows 7 recently. I have installed all necessary drivers: Intel, Realtek, ATI Radeon Card, Toshiba controller. The BSOD only occurs in these time: when booting Windows Booting screen, at the log in screen, and in some strange manners (I have a USB mouse and keyboard; sometimes they were hanged and then run again; sometimes hanging and then BOSD occured). I have used Memtest+, and Prime86 but those didn't detect any problems. I have used WinDbg find the problems but then I cannot trace what the real problems are, so I need your help to identify what my problems are. Here is the zip of my dumps file.View attachment Minidump.zip Sorry for inconvenient because English is not my native language. I appreciate for your helping.
