Hi!

If you're starting up your computer, press F8 before the Windows logo appears and select "Start Windows Normally".

If you need to exit it whilst inside of Safe Mode (booted into Windows), follow the instructions below:

How to Exit Safe Mode

Hope this helps!

start your laptop before booting windows press f8 button continuously

If you are running Safe Mode because you cannot get into Windows, you may want to first try loading the last known good configuration.

To get into the Windows 2000 / XP Safe mode, as the computer is booting press and hold your "F8 Key" which should bring up the "Windows Advanced Options Menu" as shown below. Use your arrow keys to move to "Safe Mode" and press your Enter key.

Note: With some computers, if you press and hold a key as the computer is booting you will get a stuck key message. If this occurs, instead of pressing and holding the "F8 key", tap the "F8 key" continuously until you get the startup menu.

Trouble Getting into Windows 2000 or Windows XP Safe mode - If after several attempts you are unable to get into Windows 2000 or Windows XP Safe Mode as the computer is booting into Windows, turn off your computer. When the computer is turned on the next time Windows should notice that the computer did not successfully boot and give you the Safe Mode screen.

Windows Advanced Options Menu
Please select an option:

Safe Mode
Safe Mode with Networking
Safe Mode with Command Prompt

Enable Boot Logging
Enable VGA mode
Last Known Good Configuration (your most recent settings that worked)
Directory Services Restore Mode (Windows domain controllers only)
Debugging Mode

Start Windows Normally
Reboot
Return to OS Choices Menu

Use the up and down arrow keys to move the highlight to your choice.

Once you're done in Safe mode if you want to get back into Normal Windows restart the computer like you normally would and let it boot normally. Click here to get additional information about getting out of Safe mode.

If you are running Safe Mode because you cannot get into Windows, you may want to first try loading the last known good configuration.

Trouble Getting into Safe mode - If after several attempts you are unable to get into Safe Mode as the computer is booting into Windows, turn off your computer. When the computer is turned on the next time Windows should notice that the computer did not successfully boot and give you the Safe Mode screen.

While the computer is initially booting up, press F8 (repeatedly if necessary), you should be presented with a selection screen to boot into safe mode (various levels such as with or without networking) or to boot normally. The F8 key only works while the computer is going through the BIOS startup procedure.

During boot up repeatedly press f8.
Or within Winows press start >> Run >> msconfig >> press Boot tab >> check safe boot.

try booting in safe mode. keep pressing F8 when the computer boots up till a screen with options come. select safe mode with networking. if it boots, then install avira antivirus(it is available for free download). seems like a worm/virus. if not i recommend reinstallation.
my suggestion with my personal experience is to get a clean new installation and be cautious about connecting drives/ network before a antivirus is installed.

You can also force the system into safe mode. You click on startup and type in msconfig. Click the general tab and select diags and the system will reboot to safe mode. Change it back to normal to get your system out of safe mode.

Try to boot in safe mode:
Push F8 or F2 when booting.

I would suggest that you run only one stick of Ram at a time to determine if they are the problem.. Also these CPU's had heat problems that damaged the cpu. This also causes freezing. I would consider resetting the CPU and the heat sink, and case fans are clean and working. 

pres f8 as it is booting up. then select safe mode.

Try pressing F8 as your machine gets ready to start windows. Keep tapping it until you get a menu. You can try "most recent settings that worked" or failing that try starting Windows in safe mode. If it will start in safe mode regress it to a point before your failed download using System Restore. If it won't start at all, you may need to reinstall Windows.
