The only things that can do this are: A card failure, a hard drive failure, Motherboard faiulre, A Power Supply failure, Faulty RAM. To toubleshoot.. disconnect Hard Dive, CD/DVD remove any & all cards, see if it boots,if it does, add the Hard Drive, reboot, then add the CD/DVD, reboot, then replace A card, reboot & so on... until ya find the faulty component, that stops it. If it doesn't remove ram & see if it powers up, it will NOT boot. If it doesn't ya PSU is most probably faulty. If it does ya RAM/motherboard is faulty. So basically strip it down see if it powers up. than add things one at a time to find the culprit.. then replace the ofending item.

I was running the program "windon Defender" on it and walked away. When I returned the computer was off and wasn't turn back on.


The Windows Defender Application is the Antivirus Software which will be pre-installed with the Windows Operating System(Windows Vista, Windows 7).
The Computer will always Shut down after any Windows Updates or any Operating System Updates are downloaded and installed.
If you are connected to the Internet and running Windows Defender, the Computer will automatically download the Updates for the Windows Defender Application.
Once the Updates are downloaded and installed, the Computer will prompt for a shut down.
The count down will be for 10 seconds.
After 10 seconds, the Computer will install the downloaded Updates and shut down.
This might be the reason for the Computer to shut down while using the Windows Defender.

If the Computer still shuts down randomly, the issue might be due to overheating.
All the Processors in Notebooks are designed to shut down automatically, if there is any overheating issues.
The overheating issue mainly occurs due to the malfunction of the Cooling fan.
If the Computer shuts down frequently, the issue might be due to the above factors.
It would be better to get the Unit examined at the Service Center.

Shut down suddenly


Do you get any error-beeps of any kind? Like the battery is going empty? Or does it just go off suddenly? If the first is the case, your power connector in the computer or perhaps the powersupply could be broken. It could sound like your battery doesn't get charged and your computer isn't getting power. Then it will shut down. See if the power/charge indicator is on when connected to the power grid.

If it blacks out suddenly it's probably a more severe problem, but you might try to reinstall the OS (I'm guessing windows), but only as a last resort.
