Hello cartman,

 

Have you amde sure that you are using the latest version of your browser?

 

If you, you may have some malware programs causing this.

 

Please follow this proceedure in order to clean your system.

 

Your computer appears to be infected with Malware. Malware is software designed to infiltrate or damage a computer system without the owner's informed consent. It is a combination of the words malicious and software. The expression is a general term used by computer professionals to mean a variety of forms of hostile, intrusive, or annoying software or program code.

 

We would be grateful if you could please note the following:

• Perform all the steps in the order listed to avoid any conflicts.

  • Click the Clean Up button in the System Restore section to remove all previous restore points except the most recent one.
    

   

  This will remove any infected files that have been backed up by Windows. The files in "System Restore" are protected to prevent any programs changing those files. This is the only foolproof way to ensure the deletion of those files.

   

  Note: Please don't use it on a regular basis as this will clear all previous restore points. The feature might be very useful to revert your computer to working condition if something goes wrong.

Re-enable all your security applications and please return here and tell us how the computer seems to be operating.

 

Happy Safe Computing!

 

 

Also: May I ask what Anti Virus programs/firewalls you are currently using?

And what Internet Browser do you use that has this problem?

New computers can have issues just as easily as old ones can.

 

If your pc is still under warranty.... then follow the directions as stated in the warranty. Do not attempt to fix this yourself, or you will negate your warranty.

 

More than likely you have a dirty cooling fan that is not keeping your pc cool enough. Thus the pc shuts down unexpectedly.

 

If it's not under warranty... then disconnect your pc from all power sources and disconnect all other cords and what not from the tower. Open the tower carefully, and with the eraser end of a pencil.... gently turn the blades on the cooling fans to see how freely they turn. Then with a can of compressed air.... blow out all the dust etc from the fans and inside the tower. Be sure to keep the canned air level to prevent expelling more than just air. Then try moving the blades of the fans. They should turn more freely. Put the cover back on the tower... rehook all cords etc... and try surfing the net. See how your pc does, and then post the results back here and let us know how it's going. There are other possibilities of what is going on... but let's start with this one first.

 

Again it is important to remember that if your PC is still under warranty... do not attempt to fix this yourself, as it might void your warranty.

Hate to disagree with you here DP... but malware doesn't usually cause random shutdown.

[DirtyPolo]

No problem,

I was thinking more along the lines of a virus picked up through browsing, but it's an easy mistake to make to begin with I guess :P

[help4me]

Malware removal is a good step to take to keep a pc "healthy." The guide you posted is excellent, and it won't hurt if cartman follows it. It will ensure better pc performance in the long run. I just don't think malware is the cause at the moment. :)

Control Panel > System > Advanced System Settings ( left panel ) > Click Settings under Startup and Recovery

Uncheck the box next to Auto Restart ( System Failure ) > OK

You should get an error message next time the problem arises.

Its also a good idea to take the case off the side of the PC and see if it is unusually dirty in there as a build up in heat will make the PC shutdown.

Just DONT use a vacuum to clean it, use a can of compressed air from any good pc shop or etailer and use in small sharp bursts as not to cause condensation build up on components
