Unable to use computer. Log on successful goes to home screen then after a few moments it kicks me off, reboots and repeats. I've tried to factory reset and other things suggested but none work. I don't know where my disc is. I have a hp laptop also but I have no clue where that disc is either. What else can I do?

Thanks for engaging in HP support Forums! This is a wonderful location to converse with the community, get assistance and find tips! I understand you are having issues with the computer restart unexpectedly.


I take it as a privilege to share this platform with you. We value your relationship with HP and wish to serve you better.

For better clarity and to assist you better I would require more information regarding this.


To provide you with an accurate solution, I'll need a few more details:

Have you recently made any software or hardware changes on the PC before the issue started?

Have you tried to check in the bios if it restarts?

Have you tried to run an extensive system test from F2?


In the meantime, let's try these steps here: 


Perform a Hard reset on the PC

Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a "Hard Reset". Use the following steps to perform a hard reset on a computer:

  1. If Windows is open, click Start and then Shutdown.

    If Windows is not open and the computer has power, press and hold the power button on the computer until the computer shuts off.

  2. With the power off, disconnect the power cord from the back of the computer.

  3. With the power off and the power cord disconnected, press the power button on the computer for 5 seconds. The power light indicator on or near the power button might turn on briefly but then go out.

  4. Reconnect the power cord and turn on the power.

I recommend checking if the issue appears on the BIOS screen (restart the computer and tap on F10 to access BIOS) 

This would confirm if it's either a hardware failure or a software related issues.


The best way to do that is using the HP Guided troubleshooter: 

Click here to access it (simply select your description of the issue from the bottom of the screen to gain access to the next set of steps that should resolve your concern).




Alternatively, you can go through this link which should be helpful:  HP PCs - The Computer Restarts Unexpectedly (Windows 7)


If the issue persists, this could be hardware related. To isolate the issue correctly, Please run complete system diagnostics from this link:  HP PCs - Testing for Hardware Failures

It takes about 2 hours to run. If it restarts during the system tests, then the issue is clearly hardware related and the unit needs to be serviced by contacting HP phone support. If any component fails and displays a failure code, please make a note of it and contact HP phone support also, to get the unit serviced.

Please let me know if this resolves the issue, or if you require further assistance!


Eagerly waiting for your response!

I hope you have a good day ahead,

And Feel free to ask your queries as this forum has some of the best people in the world available and ready to help.
