Hello there. I have a 8 months old Toshiba Satelite l650-11r laptop and lately I've been experiencing blue screens of deadth. Unfortunately I cannot really say when they started happening (I delete my logs every few months). I have Windows 7 Home Premium installed which was installed by a manufacturer together with all necessary drivers for network, graphic adapter, etc. I haven't had a chance to format and reinstall Windows because I need my laptop in school on a daily basis. I must say that Blue Screens are not so frequently (like every 2 weeks) but it is very annoying when I leave my laptop turned on and when I come back I see either "Disk Error occured. Press ctrl+alt + sth to reboot" or Blue Screen. Sometimes I get a Blue Screen even when I'm working. I've included logs from event viewer but I had to translate them because they are not in English. I hope you can help me with information I provided because I would really want to know if these blue screens are hardware or software related. Thank you in advance for your help. I've included logs from event viewer and minidump files. You can find them here -> http://cid-f579d52f31585d80.skydrive.live.com/redir.aspx?resid=F579D52F31585D80!458

******************************************************************************* * * * Bugcheck Analysis * * * ******************************************************************************* SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (1000007e) This is a very common bugcheck. Usually the exception address pinpoints the driver/function that caused the problem. Always note this address as well as the link date of the driver/image that contains this address. Some common problems are exception code 0x80000003. This means a hard coded breakpoint or assertion was hit, but this system was booted /NODEBUG. This is not supposed to happen as developers should never have hardcoded breakpoints in retail code, but ... If this happens, make sure a debugger gets connected, and the system is booted /DEBUG. This will let us see why this breakpoint is happening. Arguments: Arg1: ffffffffc0000005, The exception code that was not handled Arg2: fffff80002cdbbfa, The address that the exception occurred at Arg3: fffff880077a1f98, Exception Record Address Arg4: fffff880077a17f0, Context Record Address Debugging Details: ------------------ EXCEPTION_CODE: (NTSTATUS) 0xc0000005 - The instruction at 0x%08lx referenced memory at 0x%08lx.

So basically all BSOD were caused by this network driver ?
