My VAIO has been randomly rebooting itself when I try to shut it down or put on stand-by. After such crashes Windows XP displays a serious error dialog. Happened a few times already. WinDbg identified ialmdev5.dll as the culprit based on one mini dump. Do I need to update the Intel 945GM drivers? Which ones should I go for if my motherboard is Phoenix Technologies R0020J4? The other dumps refer to win32k.sys as driver fault. I have not seen BSOD though. Help.
