Hello guys.Here's my strange problem.So i was with Windows Vista and i was browsing the internet when suddenly the computer stops working.I mean my mouse stops working, my keyboard and the OS too.The lights of the keyboard (caps lock, num lock) turned off.The laser of my mouse too.The windows stops completely too.It stays there like a picture.I mean even the emoticons werent moving (hope you understand me ).So i decided this was some virus and i put a fresh copy of windows seven.Everything was good, but then after 20 minutes (i was installing some players and antivirus program) it happened again I cant explain this.Hope you guys help me.I bet its some kind of hardware problem.Thanks in advance, guys

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 freeze 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, try to find which *.sys file is cause the blue screen. Usually it is listed in the bottom part. Arthur Xie - MSFT
