Hi! My laptop is Lenovo Y460, with Core i3 330M and ATI 5650 mobility graphic card. I have 1 crash every 2 or 3 days. It happens regardless of what I'm doing (working, surfing or gaming), I suppose my blue screens are absolutely random. I think I have updated all the drivers, but the blue screen keeps on appearing. Win Debugger says that the problem may be caused by tcpip.sys, wininit.exe or ntoskrnl.exe, but this doesn't give me any hints to solve my problem. Please, find here some of my latest dump files in a .zip file. http://www.2shared.com/file/K4jpUQsR/crashes.html Thanks for help!

IMAGE_NAME: tcpip.sys FAILURE_BUCKET_ID: X64_0xD1_tcpip!Ipv6AddressType +3a Do you use IPv6? if not, try to uncheck it in the network and sharing center to the network connection. Also try to update the Atheros wireless driver: athrx.sys Thu Apr 01 03:54:32 2010 Also update all other old drivers: WDMirror.sys Tue Jun 17 08:37:30 2008 the CRITICAL_OBJECT_TERMINATION (f4) crash is caused because your Windows was out of RAM: // // MessageId: ERROR_OUTOFMEMORY // // MessageText: // // Not enough storage is available to complete this operation. // #define ERROR_OUTOFMEMORY 14 L EXCEPTION_CODE: (Win32) 0xe (14 ) André"A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

Thanks for quick responce, much appreciated! I've followed your recommendations and no crashes so far. The only exception is the Atheros wireless driver because the newest version is not signed by Microsoft. I know there exists some software to overcome this, but I'm afraid it can modify my boot sector as I use 2 operating systems. Once again I thank you for writing.
