Installed on new hard drive. No problem started right up. Did updates and would not restart. Will start and run in Safe Mode with networking. Disabled all drivers and tried to restart. Still does not restart. It will get to the starting windows screen but after it runs for awhile the screen flickers twice and reboots.If I restore to early point, it works just fine. What can I do next?

If you restore to an earlier point, but then you mention a new hard drive. Clearly though the problem seem to point to a driver and you're not getting any error messages at ALL? Not even in the event manager? Was this an upgrade from Vista or a clean install? What machine is this - be specific to make, model and model # so we can best assist you. Did you do a bios upgrade? Have you checked device manager to see if there are any problems with any devices? You can also do a driver verifier testFor more information about Driver Verifier, see Driver Verifier. Driver Verifier monitors kernel-mode drivers and graphics drivers to detect illegal function calls or actions that might corrupt the system. It can subject the drivers to a variety of stresses and tests to find improper behavior. Driver Verifier is included in Windows 2000 and later versions of Windows. Driver Verifier works on both the free and checked builds. The following sections explain the operation of Driver Verifier: Driver Verifier Options describes each of the actions of Driver Verifier in detail. Using Driver Verifier explains how to activate Driver Verifier, how to choose which options are active and which drivers will be verified, and how to monitor the behavior of drivers being verified. No Reboot Feature describes the functionality, available in Windows Vista and later versions of the Windows operating system, that helps to eliminate disruptive reboots. With this functionality, you can use Driver Verifier on production servers that cannot afford to reboot. Additionally, you can monitor your driver while you attach and remove devices. <!----> You can run Driver Verifier on multiple drivers simultaneously, or on one driver at a time. It can perform a variety of actions, and most of these can be optionally enabled or disabled. This allows you to put a driver through heavy stresses or through a more streamlined test. Driver Verifier can verify any number of drivers. However, the Special Pool and I/O Verification options will be more effective when used on one driver at a time. Note On Windows Vista and later versions of the Windows operating system, Driver Verifier runs only with elevated privileges. For more information, see The Verifier Utility. The Verifier utility, Verifier.exe, activates and monitors Driver Verifier. This utility is located in the %windir%\system32 directory of Windows. There are two ways to use the Verifier utility. Command line. To use Driver Verifier at the command-line, in a Command Prompt window, type verifier followed by at least one command-line parameter. Driver Verifier Manager. To open the Driver Verifier Manager graphic user interface, in a Command Prompt window, type verifier (with no parameters). On Windows Vista and later versions of Windows, a Windows Security dialog box prompts you for permission to run Driver Verifier Manager. To run it, select Permit. <!----> Note Driver Verifier Manager in Windows XP and later differs slightly from the version of Driver Verifier Manager in Windows 2000. This section includes: <!----> Verifier Command Line Driver Verifier Manager (Windows XP and later) The Windows XP and later version of Driver Verifier Manager begins with a screen which allows you to select one of five tasks. Whichever task you choose, you will be shown a series of screens that can be navigated by using the Back and Next buttons. When this sequence is complete, use the Finish button to save any changes you have made and exit Driver Verifier Manager. If you wish to discard your changes, use the Cancel button. The following tasks can be chosen from the first screen of Driver Verifier Manager: Create standard settingsSelects a standard set of Driver Verifier options, and then allows you to select the drivers to be verified. These settings will take effect after the next boot. See Selecting Driver Verifier Options and Selecting Drivers to be Verified for details.Create custom settingsDisplays all Driver Verifier options and lets you select from among them. Then, it allows you to select the drivers to be verified. These settings will take effect after the next boot. See Selecting Driver Verifier Options and Selecting Drivers to be Verified for details.Delete existing settingsDeactivates all of Driver Verifier Manager options and deletes the list of drivers being verified. This takes effect after the next boot.Display existing settingsDisplay the options that will be activated and the drivers that will be verified after the next boot. It does not include any volatile settings. See Viewing Driver Verifier Settings for details.Display information about the currently-verified driversThis will display statistics related to Driver Verifier's actions. See Monitoring Global Counters and Monitoring Individual Counters for details. It will also allow you to view and alter Driver Verifier's volatile actions. See Using Volatile Settings.Ok so I gave you all that info, here in a nutshell how to do itYou can try using a tool called driver verifier. If this tool finds a problem, your machine will crash again. Hopefully with it enabled, it will allow you to easily identify the bad driver.Enable driver verifier1) Open an elevated command prompt2) Type "verifier /standard /all" (no quotes)3) Reboot your machine4) Use machine again until it crashes After the crash & reboot, go into safe mode. Disable driver verifier1) Open an elevated command prompt2) Type "verifier /reset" (no quotes)3) Reboot your machineAfter it crashes, look in c:\windows\minidumps for a memory dump file.

I am doing as requested, about retart number 20, but it still has not failed to start. This was a clean install on a new hard drive. I am puzzled why it runs just fine until the updates are run. If it was a driver issue would it not fail before the updates? Also, I disabled all drivers and it still would not start.Will update if it finally fails.

Not necessarily, it may be a program or new driver installed that could be causing the issue. So you did the driver verifier and you let it run for some time now and it didn't crash? Have you now turned off verifier (after how long did you let it run?) You can't just disable all drivers, going into safe mode will load the minimum set of drivers needed to start. I'm curious how you're disabling ALL drivers when it doesn't start.You choice of words like "will update if it finally fails" doesn't make sense because on one hand you say it doesn't start, but then you say just the opposite in the next sentence. It could be that the updates are installing new drivers for something - look at the updates list and see what it is installing. 1 - So you're saying that Windows 7 IS starting up just fine now right?2 - But it won't start if you get updates - is that what you are saying? 3 - So you did a restore to an earlier point got it to working and it hasn't failed to start since right?4- You have applied updates again - correct? and now its still booting up just fine right?Just clarifying some of these points so we'll know you're functioning.
