The computer will not start at all. It goes into the start up screen. The options to choose from are safe mode start up, etc. It will not go past this. What could possibly be the problem?

Booting into safe mode usually indicates a problem with the machine. When powering it on, keep punching F8 for the "Safe Mode" boot option window and try choosing "Last good Configuration". You might try Restoring it back to before this started. Click Start, Programs, Accessories, System Tools and then System Restore.

There are many different things that could cause the issue you describe.

About how old is this computer? If it's between 3-5 years old, you may want to consider purchasing a new one.

Has anything changed recently? Did you install software or other updates that may have caused this issue?

When it goes to the screen that lets you choose Safe Mode, etc., do you have an option that reads "Last known good settings?" If so, choose that option to start the computer with.

Follow the steps below,

Step 1: Shut down your PC completely.
Step 2: Turn on the Power button.
Step 3: As soon as you turn it on start hitting the F8 key on your keyboard until you get to a black screen called "Windows Advanced option". (If you don't get to that that screen but you end up reaching the blue screen than that means you have delayed in hitting the F8 key. start again from step 1.)
Step 4: As soon as you reach "Windows Advanced option" use your down arrow keys to choose an option called "Safe Mode".
Step 5: Select that and HIT ENTER.
Step 6: If you able to login then try accessing System Restore.
Step 7: Click on Start and then click on All Programs.
Step 8: Choose Accessories and then System Tools and System Restore.
Step 9: Run the wizard by choosing "Restore My computer to an Earlier stage"
Step 10: Choose a date displayed in Bold in the calender.
Step 11: Your computer would reboot and wait until the restoration completes.

Hope this helps.

Your best bet is to replace the keyboard. They are cheap (under $20.00) and easy to replace. All other options involve making a bootable flash drive (more complicated and you still have a broken keyboard)

Try start up in Safe Mode press F8. Choose Safe Mode, when at the choice window, to select either Safe Mode Desktop, OR System Restore, chooses system restore and choose a time before you had the "Problem" and follow instructions. This should get you back.

Had a similar problem like this several times. Try choosing safe mode. Safe mode will load the required drivers. After safe mode finishes the loading process, restart your computer and choose to start windows normally. The problem you mention usually happens when the computer is turned off without using normal shut down procedures. Also happens when you have a sudden power outage.

Start your PC in safe mode, to do this repeatedly tap the F8 key as soon as you turn the power on. This will then bring up an "options" screen listing boot in safe mode, safe mode with network support etc. Just use safe mode. If it goes directly to windows instead - shut it off and try again til u get the safe mode screen. The arrow keys control the selection to choose.When it starts in safe mode a black screen will usually appear with a bunch of writing, this is normal, after that it may "hang" for as long as 5 minutes, before coming up with a login screen. Sometimes hitting enter or escape will bring up the login screen faster. When you have a login screen, login and disable the updates using the software control options for the software that is trying to update. You might also go to control panel, administrator options, then services and disable automatic updates temporarily. When your pc starts in safe mode - it starts with minimal drivers and does not run updates- this allows you to change settings. You can then reboot normally and it should start properly without updating before starting.

You need to borrow a XP cd so that you can repair your installation

If you choose Start Normal and it boots into safe mode again then you should get professional help if you value any of the files on your computer and don't want to loose any data.

I would recommend you try to do a installation repair. Do so by booting from the Windows install CD and choosing the repair option.
