If your computer was able to boot up but unable to load the Windows, the most common cause would be the recently intstalled software or Windows update.
To remove this, follow these steps. Skip Step 1 if it is not relevant.
Step 1: Removing recently added hardware
Use the steps in this section to disconnect any recently added hardware and test for the error.
NOTE: If a new internal device (sound card, hard drive, or other) was added to the computer before the error message started to occur, you have to remove it before continuing.

Does it display on your monitor "No Input Signal"? If so it could very well be your motherboard. Same thing happened to me. :(

Do you see the BIOS splash screen or anything?
Try booting into safe mode by pressing F* as soon as you power on the computer. If the monitor works, then it is a bad driver. Roll back to a previous restore point, boot to last known good coonfiguration. Last Known good configuration is available from the same as the safe mode screen.
If this is helpful, please comment and rate. Have any other questions, please let me know.
