From the moment you switch your machine on you should hear a beep, just keep tapping the F8 key and you should load to a black screen with white lettering.
In the black screen use the keyboard arrows to move up the screen and select Safe Mode.
IF your machine will boot into safe mode right click on My Compter, in the Window that opens select System Restore in the tabs at the top, now follow the instructions to restore your machine to a date and time back before this problem started.

    does it get by the BIOS tests ?!or it get;s stuck there ?! i think so if F5 F8 doesent work... If u dont know if it passed BIOS tests u can test a linux live cd
    (ubuntu for example)and see if it works(the comp must be set to boot
    from CDrom).

    if it doesn't pass BIOS then reset the BIOS, and see if it works.

    Also try removing and reinserting all the comp;s components (harddrive, memory ...etc...) maybe there is a faulty connection somewhere.

    if it still wont work then there is a hardware issue ! try removing from components ... the hard drive ... see if anything happens ...the memories .. .(some beeps should be heard, if not than the motherboard is most probably faulty ) these things and then give more info if it still wont work ...

My HP Pavillion dv7 3112sa won't boot and remains

Hi, at startup try pressing f8, this should give you a menu, select 'start windows with last good configuration', this should restore windows to the state before it started rebooting randomly. Failing that...try starting in 'safemode with command prompt' and then do a 'system restore'- press f8 again at start up and then follow the instructions below. this should restore your system to a previous state when the computer wasn't doing random things.

  1. Restart your computer, and then press and hold F8 during the initial startup to start your computer in safe mode with a Command prompt.
  2. Use the arrow keys to select the Safe mode with a Command prompt option.
  3. If you are prompted to select an operating system, use the arrow keys to select the appropriate operating system for your computer, and then press ENTER.
  4. Log on as an administrator or with an account that has administrator credentials.
  5. At the command prompt, type %systemroot%\system32\restore\rstrui.exe, and then press ENTER.
  6. Follow the instructions that appear on the screen to restore your computer to a functional state.
I hope that this helps you to sort out the problem. Toni

It looks like your going to have to perform a full system recovery as you are not getting anywhere with start-up repair or safe mode.

For a full system restoration, press the F11 key during bootup and then select "Recover PC" from the menu.

When I start up my computer, i cant access anything on the screen. It just freezes and then I restart it and then it does it again. Help!

it is probably a program that starts up overloads the system resources, so everytime it starts it freezes. what you can do is go into safe mode (go into safe mode by hitting f8 right before windows logo comes up when you start your computer, or right after dell logo. either that, or if you restart it wrong, it should give you the option of going into safe mode) then when you log onto your account, a window will pop out, just click yes. then either go to start menu on run(if you have windows xp) and type msconfig. then a window will pop out, when it does, go to the startup tab, and uncheck all of the boxes. click ok, and click restart, (for windows 7 its the same thing but instead of using run, just type it in the search bar on the start menu). go to start windows normally, if it still doesnt work, when you restart it, go to last known configuration. Hope this helps. If you need any clarification, just let me know, ill check in. Goodluck

My HP a800n (using XP) worked fine yesterday. Last night, an automatic update came in from Microsoft. Today, I cannot get it to consistently boot up. It did it once earlier and locked up. Now, I get the...

Try to boot up into safe mode and see if you can get in there. If so then go into the system tools folder in the start menu or by going into the windows icon. You would go into accessories and then system tools and then go into system restore.

In the system restore choose the last good known date that is bolded when the computer was working properly. After you click on the date to choose it go ahead and let it restore. It will need to reboot, once it does if it goes back in then your good. At that point I would suggest turning off automatic updates for windows.

If you can't get into safe mode, then your going to need to reinstall windows cause the operating system is corrupted.

Most of the time you simply need to go into safemode once then you should be able to get back into Windows normally. You get into safemode by pressing F8 before Windows starts but after the HP logo screen when you start the computer. You may have to try a few times to get the timing right.
