I have an hp v3000 labtop ....... It starts up and first says something about imminent failure and to press f1........ after that its loads the windows screen then flashes blue really quickly and kinda re-starts again going back to the windows screen and doing the same thing Bottom line is its loops and wont start goes as far as the windows loading screen then starts over what should i do PLEASE HELP BEEN LIKE THIS A WEEK NOW

Turn the laptop off. When you turn on the laptop, hit the F8 key repeatedly. This should get you a menu which will give you options to different start modes including Last Known good configuration, Safe Mode, Safe Mode with Networking, Safe Mode with Command Prompt.

You can first try Last Known good configuration and see if you laptop will start propertly this way.

If that does not work, you will want to try starting in Safe Mode. In Safe Mode you can try to use Windows System Restore. You find system restore in the Help and Support menu in the start menu. You can try to restore to a date before you started having the problem.

I hope that his is helpful.

This means that your hard drive has failed -- it is no longer imminent.
Every time that you allow it to try to boot from now on you're allowing the drive to eat itself up more and more. If you want to have a hard drive recovery service be able to get anything off of it, stop trying to boot from it any more.
Take the computer in to a service center and have them replace the drive and re-install the operating system. Hopefully you have a backup of your data, because otherwise you've probably lost it all.
