What Could Cause My Computer To Shut Down For No Reason?


What brand of pc is this? Download a diagnostic program to test internal functions. Sounds like maybe a motherboard or power supply issue.

Sounds like you have a virus or infection. Boot the system in Safe Mode.

Maybe you have a virus or infection that is shutting you down if it is not running hot and you are allowed to work on the computer for a while before it shuts down. Boot the System in Safe Mode and see if it shuts down.

Turn off the computer, then hit the power button to turn it back on and immediately start hitting the F8 key repeatedly until you see SAFE MODE. Take the Safe Mode With Networking option (this will give you internet connectivity) and let it boot up. Safe Mode will look different to you, the screen will be darker and the icons bigger, this is normal. Download and install MalwareBytes and run a Quick Scan.

Go to www.google.com and in the search box type: "Download cnet Malwarebytes" (without the quotes). Download and install malwarebytes from the sites download.cnet/malwarebytes. When the site opens up click on the Green Download button on the left. Do not click the Red Download button, that's junk. When it finishes installing the Gui Interface will open up with an offer to Accept a Trial Version or Decline. CLICK DECLINE you want the totally free version. Run a QUICK SCAN. As it scans, if it finds infections the number will be in red. When it finishes scanning, click SHOW RESULTS. A notepad text document will open up showing you the results. You can close the text document and go back to the Gui Interface where you will click REMOVE SELECTED RESULTS. The objects will already be selected for you. When it finishes removing the objects click ok and it will sometimes reboot your machine.

A virus had shut down my administrator account and now I use my guest account. I want to add a new account so I can use that as my administrator account, but my administrative password will not work at...


Re-install Windows, choosing to install Windows to a different folder-name -- anything *OTHER* than 'C:\WINDOWS'.
Then, when logged-in to the "new" version, you can virus-scan your computer, and access all your files from the "old" installation.

Maybe, the virus-scan will clean-up the "old" installation.
Shutdown, restart, and choose to boot from the "old" installation.

Hi chief1ang,

Please do not install or open this program. It is a malware. I have dealt with this malware a few times already at work and it's nothing but a pain in the u know what. On 2 different occassions on 2 different pc's I had to scrub the hard drive, image, and re-install proprietary programs. Before I this I tried to scanning it with our corporate anti-virus program and it would detect the virus and says it removes it but when I re-scan it the same virus continously shows up. I did a search on the web and discovered that this virus hit alot of people and companies.

Please do not install it.

Computer shuts down.


Hello;

So i guess that the PSU is good. As i diagnose of what you have said, i digested a conclusion that when the computer shutdown when application run. there a problem conflicting the application to another application or such an application trigering the system to shutdown.

Some causes of this problem are:

The system is infected by known and unknown virus
The driver of the system are not properly installed
The application program committed an errors trigering the system to shutdown.

Possible solutions:

1. Scan you system with a potent anti virus
2. Remove the installed driver of the sytem and reinstall it after restarting
3. Unistall the application that causes shutdown problem and you can reinstall it after restarting.
4. remove newly installed hardware or install the correct driver of the hardware.


Note in scanning your system with antivirus you should scan it it safemode.

If all the solution did not work to your system. please notify me for further solution.

best regards, melnavz

My computer went back to older clock date as 1610


try starting your computer in safe mode and see if you can do anything productive there, like scanning for viruses or spyware. also check if you can do the following:
CTRL+ALT+DEL (open task manager)
goto Start>Run>Regedit (open registry editor)
goto Start>Control Panel>Display>Properties (change display settings)
right click on clock at tray and change the current time to correct settings

if you cannot do any of these activities, then your computer may probably been compromised by a virus or malware.
