System freeze with Windows 7
Hello Guys, I've a strange problem with Windows 7 Professional, 64 Bit. After the startup the system complete freezes and i can just press the power button to restart the system. The problem occurs just, when the system is more than 8 hours turned off. After a simple restart, the system runs normal without a freeze. This problem didn't appear with Windows XP SP3, 32 Bit. My system: Intel Core i7 920 4x2.66 GHz 8MB Cache Ram: Mushkin 3x2GB 1333 MHz DD3 Harddisk: Samsung F1 750 GB Graphic: Point of View GTX295 1792MB DDR (power supply at least 750 W) Power Supply: Aerocool Horese Power 750 W Mainboard: Asus P7T Deluxe Steps i've already done: - Virusscan - BIOS Update (Every component of my computer is compatible with the mainboard) - Updated all drivers with the windows 7 compatible version The eventlog shows following entries: Pic 1: http://img686.imageshack.us/img686/198/fehler1.png Pic 2: http://img130.imageshack.us/img130/5020/fehler2.png Pic 3: http://img199.imageshack.us/img199/7482/fehler3o.png Can the DriverFramework (UMDF reflector) be the source of the error? In the picture 1, the message says: The UMDF-Reflector cannot complete the startup because the service WUDFPf cannot be found. The Service will maybe start after the next restart and then the system will try to restart the device. I've also reinstalled windows XP 32bit and the system worked normal. Thanks for your help in advance! Regards Lars

Without looking into the errors you posted at all, this comes to mind:If the problem manifests only when the system is cold, then it sounds like it could be a hardware problem in which some connection or circuit is intermittent due to the minute changing of physical dimensions due to cooling/heating. It's hard to imagine how a software problem could manifest like that.Also, it's possible Windows 7 is more rigorously checking the hard drives (e.g., via the SMART interface) than XP was and that one of them is marginal until warmed up.I'd open the computer, clean out any dust, and reseat all the cards, RAM, and connectorsas a first step.-NoelP.S., It may not be the "green" thing to do, but I prefer to leave my computers on 24/7. They have lasted longer and been very stable with that treatment.

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 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.

WIN 7 x64 680i mobo. 4850 video card. I was having these problems every day until recently. I'm getting the feeling a lot of it is sound related What I did was go to realteks site directly and go to their downlaods page. I downloaded their audio driver. Not the ATI HD driver or any of that. Just the plain old fashioned realtek driver. the ATI driver self installed, could be part of the exe package. Then I went to my device manager and looked under sound. I uninstalled every audio driver in there. I then installed the new driver. it appears that a default driver windows will try to install on your pc will cause conflicts. It can seem like they are video related because most of the time your hearing something, your also seeing something.. IE: playing a game with sound.. I haven't had a single browser freeze since I did that and my surround picks up properly again. It wouldn't even work on quadraphonic but now it will. I use a 6.1 system but it was still odd that quad would just do nothing in testing. Been playing games for hours on end as well. It was really starting to drive me crazy having to power swith off like 3-4 times a day due to freezes. it was like it was getting worse. Now it's smooth sailing. Hope this helps some of you. Cheers. :)
