I recently installed windows 7 on my laptop, and it ran fine for a while then all of a sudden started shutting off randomly, in the midst of troubleshooting, it will not even get past the boot screen now before either the screen goes nuts with colors , just stays black, or the computer just turns itself back off. I have tried a million times to boot in safe mode, last known working boot, nothing works, i need some serious help!!!!!!!!!!!!!!!!!!!!!!! Thanks

I fixed this issue, I too had the same problem. Here is how I did it. 1) Reboot and press F8 2) Select "Repair my computer" 3) Select the keyboard layout and lanugage 4) When you reach system recovery tools, select System restore. 5) Select the restore point when it was working fine and restart the computer. For More Information and know how to resolve windows 7 won't boot problem

Hi, First, you may try to perform System File Checker in Windows Recovery Environment (WinRE). You can access WinRE using F8 at the boot menu, select Repair Your Computer to start WinRE. Also, I would like to confirm that if it is able to boot the system in safe mode. If so, I suggest try system restore in Safe mode and see if you can make any progress. You can also choose system restore from the System recovery Options. This problem might be caused by incompatible or unstable hardware devices, if Safe mode does not encounter the issue, refer to the following steps to disable them in Device Manager. In this situation, your system will only have basic hardware devices and it should be more stable. 1. Click "Start"-> type in "DEVMGMT.MSC" and press Enter. 2. Expand "Sound, video and game controllers". 3. Right click on your sound card and then click "Properties". 4. In the "Device Usage" dropdown menu, please choose "Do not use this device (disable)" and click OK. 5. Please use the same method to disable other potentially unstable hardware such as the modem, network card, and CD-R drive. Please note some devices such as the video adapter cannot be disabled. After that, please restart your computer. If your computer boots properly, we can re-enable the devices one by one to narrow down the root cause of this issue.
