These such type of issue we face many times in our working life. So here I suggest you some common issue and it solution to make your life trouble-free.
There are four many reasons to stop computer suddenly.

2. Post Issue
3. Boot time issue

Power Issue This is first troubleshooting step for dead computers. Every computer has a power LED in the front of the cabinet. If the power LED is not blinking follow these steps.
* Try to different power socket, may be the issue is on your home or office wiring. If you are facing the same issue with the other power supply please go ahead.
* Reseat the power cord which is connected to "Power Supply" of the tower and power the Desktop on
* If you are using laptop devices please remove the battery and power adapter for few second, it will discharge the static current. Sometimes this issue occurs due to static current.
Post Issue The term post refers to "Power-On Self-Test". This is a special feature provided by Dell to find the generate issue on the computer and tabs. If your computer power is on and your screen shows only Dell logo or no video that may be due to a post issue. Sometimes you can see an error message on the computer screen. The external devices do not show any LED light indication when the computer was facing post issue. To check these issues and resolve it follow the bellow troubleshooting steps.
* If the computer is displaying the Dell logo and does not move past that point, it has probably failed POST.
* If the power indicator lights up and it is amber or orange, this is usually an indicator that it has failed POST.
* If you see text on a black screen, the computer is currently performing the POST. If the computer stays in that condition and does not move past it, it has probably failed POST.
* If the video screen displayed anything at all during the start-up process but is now black, this probably indicates that the computer failed POST.
* If the computer is beeping or if Caps/Num/Scroll Locks are flashing, note if there is a particular pattern in which it beeps or flashes.
* If the computer is not beeping and caps/num/scroll locks are not flashing, unplug all connections and remove all media communication devices (e.g. external monitors); reconnect one at a time and check if the computer functions.
* For a notebook, press and hold the Fn key and then press the power button. This starts the pre-boot testing and will launch ePSA. In case you have a Desktop at the Dell logo screen tap the F12 key to enter One-Time Boot Menu and use the arrow keys to highlight Diagnostics and press enter. Some Desktops do not have an F12 key, to access the boot options you have to press the <0> (zero) key at the Dell logo screen.
