Windows Not starting UP

Can you get into safe mode?

Yes-
In Safe mode, go to start, programs, accessories, system tool, system restore. Try restoring your computer to a point that is was working .If that does not work, boot back into safe mode, press and hold the windows key (has the windows flag on it) then press R. You should get a run box.

Type "msconfig" in the run box and and enter. Click on the "startup" tab and then click disable all. Click on the "services" tab, check "hide all microsoft services", then click "disable all". Now apply the changes and try rebooting back into normal mood. If that does not work reboot back into safe mode, but this time choose safe mode with networking.

In Safe mode go to your manufacturer’s (HP,Dell,etc), find the drivers and download section, and download all the drivers for your specific model. Now Reboot again and see if it works. If this still not works we will needs to do a repair install/startup repair. To do a startup repair we will need your operating system disk ( XP,Vista,Windows7).

Put the the cd in your computer and turn off the computer, turn the computer back on, watch for a screen thats says press any key to boot from cd and make sure you press a keyas soon as you see that. If you do not see the press any key screen, you will need to go into the bios and change the boot sequence so that the cd-rom drive is first (A google search should explain changing the boot sequence in more detail). This will be different depending on wich operating system you have. Assuming you have Windows7 , hit next on the choose language to install page, now click the repair your computer link, then follow the directions on the screen to perform a startup repair.
