Windows 7: Windows crashes, then upon restart powers off at "Starting Windows"

My computer has been crashing lately and I cannot find the reason why. I have wiped my hard drive and re-installed all my programs. This event can go weeks without showing up, and then occur 6+ times in the span of 3-4 days. When my computer does crash, it always freezes and turns off at the "Starting Windows" screen on boot up. It usually takes about 4 times turning on my computer to get it to actually work, no matter how long after the initial crash.

And then use this tool to post all the files here

Here is everything I believe.

The posted system logs are only till 2012-07-19 .

Please go to event viewer directly and right click on the system logs and save it as .evtx file as shown below and upload here

Here is the required information.

Based on what i could see from the logs is that all errors are related to your application... like your games etc... caused msvcr90.dll... or the microsoft visual c++ runtime.... Updating this should resolve issue with that...

the main problem...is that there are no BSOD dumps to analyse and tell you that the crash was due to hardware or software.....

So based on what you said... since the crash mostly occurs during startup...

lets first enable bootlogging ....

You can enable or disable boot logging by using the MSCONFIG utility. Follow these steps in Windows 7 and Windows Vista:

1. Press Win+R to summon the Run dialog box.
   
2. Type msconfig and press Enter.
   
3. In Windows Vista, type the administrator’s password or click the Continue button.
   
4. Click the Boot tab.
   
5. Place a check mark by the item Boot Log.
   
6. Click Apply and then OK.
   
7. Click the Restart button to restart now.

After restarting your system got to your windows directory and look for ntbtlog.txt.. upload it here

It only crashes on start up after the initial crash while the computer is on.

Here is the ntbtlog.

Is there anything I can do?
