When I start my Computer after it has been turned off overnight (switched off at the Power supply) I get a Blue screen and have to reboot the PC. in the Event log it has this error: Event ID 1012 - DNS client events - There was an error while attempting to read the local hosts file. Once the PC has booted evrything is O.K. I can restart the PC with no problems, it only seems to happen if the PC has been switched off for a while. I am connected to the net via an Netgear dg834v4 Modem/Router Windows 7 Ultimate Intel Q8200 CPU 2 x 360 Gb HDD ATI 4680 !Gb Video Card Digital HDA X-Mystique 7.1 Sound Card Aver media 777 TV Tuner card. Thank you jeepers01 After further Investigation it seems that this error is Not responsible for my Blue screening......I started my PC after leaving it off all night, and it started normally, but i still have this error in the Event Log - System.....I have searched the Technet forums (and there is a lot of ID 1012 errors) but non relating to my problem....If anyone knows what is causing this error and how to fix it, i'd be Grateful....although it does not seem to affect the PC in any way that i can see. thanks jeepers01

Since Windows system uses separated user mode and kernel mode memory space, stop errors are always caused by kernel portion components, such as a third-party device drivers, backup software or anti-virus services (buggy services). The system goes to a BSOD because there is some exceptions happened in the kernel (either the device driver errors or the service errors), and Windows implements this mechanism: When it detects some errors occur in the kernel, it will kill the box in case some more severe damage happens. Then we get a blue screen or the system reboots (it depends on what the system settings are). To troubleshoot this kind of kernel crash issue, we need to debug the crashed system dump. Unfortunately, debugging is beyond what we can do in the forum. A suggestion would be to contact Microsoft Customer Service and Support (CSS) via telephone so that a dedicated Support Professional can assist with your request. Please be advised that contacting phone support will be a charged call. To obtain the phone numbers for specific technology request please take a look at the web site listed below: Microsoft - Help and Support If you are outside the US please see Microsoft Worldwide Home for regional support phone numbers. Meantime we can try some available steps as a general troubleshoot. 1. Please remove the antivirus and run the system with a period. If the issue does not occur, mainly focus on antivirus settings and compatibility. 2. Disable Automatic Restart and see detail information on the blue screen. 1).Click Start, in the Start Search box enter sysdm.cpl. 2).Click the tab Advanced. Under Startup and Recovery, click the Settings button. 3). Uncheck “Automatically restart”. 4). On the drop-down menu “Write debugging information”, choose “Small memory dump”. 5). Click OK. When Blue Screen displays, you may find some useful information.Arthur Xie - MSFT
