The computer is taking too much time to process

The time it takes for a Dell Latitude E6400 to complete a diagnostic boot can vary depending on several factors, including the specific hardware configuration of the computer, the number of diagnostic tests that are run, and the condition of the hardware.
Typically, a diagnostic boot on a Dell Latitude E6400 can take anywhere from 5 to 20 minutes, depending on the specific model and the complexity of the diagnostic tests.
The diagnostic boot process on the Dell Latitude E6400 starts with a pre-boot diagnostic test that checks the basic functionality of the computer's hardware, including the memory, hard drive, and keyboard. This test typically takes only a few minutes to complete.
After that, the system will run a more extensive set of diagnostic tests which include PSA (Pre-boot System Assessment) and ePSA (Enhanced Pre-boot System Assessment) . These tests take longer to complete and check the more in-depth hardware such as the system board, processor, and other internal components.
You can also run an extended diagnostic test that checks all the hardware components of the computer, including the memory, hard drive, and other internal components. This test takes longer to complete and is typically used when the computer is experiencing hardware-related issues.
Please note that the diagnostic boot process can take longer if the computer is experiencing hardware-related issues, and if the computer fails the diagnostic tests, it will stop the boot process and show an error message.

Is the Operating System Windows 8?

Normally Win 8 will boot pretty fast, but if you are running a slow hard drive, the boot up process can still take some time.

Eric,

There are a lot of factors that can be a cause to slow boot up times. Sometimes it is a lengthy process to figure out what or why the boot time takes so long.

In Windows XP the first step that I would perform is to click on Start>Run and then type: "msconfig" and click OK. (Don't put in the " marks.)

Once you are in the System Configuration Tool, click the Startup tab. Disable all of the items in that list. Then click the Services tab. Check the Box for "Hide all Microsoft Services" and then disable all.

After clicking "OK" you will be prompted to reboot the computer. Do so. Time the boot/startup time. If it has significantly improved, then half of the troubleshooting is done. Next, you will need to go back into MSCONFIG and go to the services tab and enable a few of the services. Then apply and reboot. Make sure to write down which services you've re-enabled and make sure to time your bootup.

Through the process of elimination, you should be able to find out which service is slowing the system down. If you have rechecked all of the services and the system is still booting with an acceptable speed, then begin checking the startup items. Do the same process of checking just a few items at a time, writing down which ones you are checking. After rechecking just a few, apply and reboot, timing the boot up time.

Through this process you should be able to find the services or startup items that are slowing your computer down. Once the offending services or startup items are identified, you will need to make a decision of whether to leave that item out of the startup process or possibly reinstall that program.

If you find the offending item, and are unable to identify it by name, you can always go to Google and type that item's name into the Google search and it may give you an indication for what that startup item is, or what it is part of.

Sometimes, if you have a virus or malware, you may find the items listed in startup. If you do find a suspicious item, then you will need to make sure to run a full malware scan to remove any of those items that are unwanted.


Hope this has helped steer in the right direction to find out why your computer is running so slowly!

Take a look at my published guides entitled:
How to Perform a Defragmentation of your Hard drive, to increase Performance!!!
How to Decrease the Boot Time of My Computer/Laptop!!! Make My Computer Quicker!!!

The more processes that your computer has to execute on start-up the longer it is going to take to fully boot up.
Unistall any applications that you do not need.
Keep that mainboard cool, install fans in your chassis.

Take care!

I don't know about the long shutdown time but I may be able to speed up the startup time.

(Assuming you have Windows Vista or 7)
Go to the Start menu and in the "Search" field type in "msconfig" (without the quotation marks" ")

Click the on "Boot.Ini" tab and check "NoGuiBoot". Now on the right where it says "timeout" change the 30 secs. to 15 secs.

Now click on the Startup tab. Tell me all the processes that are on here. If there's more than 15 or so then it's no wonder your computer is starting up slowly. This should dramatically speed up your PC and improve performance.

This is the normal time taken for the computer to boot and the modem to access the internet

First boot the modem then the computer

By the time the computer boots the modem will be ready to connect

If this doesnt work clear the Cookies and Cache from the computer

This happens when the computer gets full of "junk" (this happens with any computer over time) and can be remedied with a fresh windows install.

If you don't plan to reinstall windows in near future I suggest you go to Control Panel -> Add/Remove Programs and uninstall any software you don't use/need

Also tweaking the system registry migh help speed up boot time:

1. Click ‘Start’ then 'Run’
2. Type in ‘Regedit’ then click ‘Ok’
3. Navigate to ‘HKEY_LOCAL_MACHINE\SYSTEM\Cur rentControlSet\Control\Session Manager\Memory Management\PrefetchParameters\ ‘
4. Right-click on “EnablePrefetcher” and set the value to ‘0′
5. Close 'Regedit'
6. Navigate to 'Windows\Prefetch' folder (usualy drive on C:) and delete all its contents
5. Reboot.
7. Enjoy greatly improved boot time ;]

Hope this helps!

you should try to remove unnecessary files in your hard drive.. afterwards, try to run the disk defragmenter. this tool will help you computer to access files faster thus making your computer load up faster..
