Laptop shuts down prox 1 minute into startup.

virus

Did you check if the fan is working, and temperature is ok, you need to use a software

Is the laptop free of dust in fan and vents? Is there sufficent air flow through the laptop, bottom and side vents? Shut down ALL unnessary programs at laptop start. Try CCLEANER freeware at :http://www.filehippo.com/download_ccleaner/, this freeware program will remove the junk from your machine. In TOOLS, STARTUP, Disable ALL unnessary startup programs, In the Internet Explorer Tab, Disable/ delete ALL TOOLBARS, they are killers on broswer speed. Try MALWAREBYTES freeware at : http://www.filehippo.com/download_malwarebytes_anti_malware/ In the installation, UNCHECK the TRIAL PRO version, you want the freeware version. Run a FULL SCAN, DELETE ALL RESULTS. Reboot machine. Take a look at this: http://www.pcworld.com/article/143538/windows_vista.html

What's the Startup Screen or Startup Page? Are you saying the laptop keeps rebooting as if you had Pressed the Power Button? Does it give you any error messages?

Is your battery working? Unplug the Power Cord and see if the laptop works with the battery. If not, then maybe your DC Power Jack where the Power Cord plugs into the laptop is broken or loose.

Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.

Maybe you have a Virus or Infection that is causing your system to shut down. Download and Install MalwareBytes then 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.

Maybe your system is running hot and shutting down to cool off. When it shuts down are you able to restart it immediately or do you have to wait and let it sit to cool off then it will restart?

Three things that will make a laptop run hot and shut off.

1. Dust - Dust inside the laptop, dust clogging the vents and fans. Dust around the cpu and heatsink. It's best to take a can of compressed air and blow out the dust.

2. A Fan that is not working. You'll have to take the laptop apart to fix it.

3. The Thermal Paste around the CPU and Heat Sink had dried up or is too thin to keep the unit cool. You'll have to take the laptop apart to get to it.

It sounds like your "automatic shutdown on error" setting is turned on. Here are the instructions to turn it off:

Restart the computer and press the f8 key to open the Advanced Boot Options menu.
Select the "Disable automatic restart on system" failure option.
Restart the computer to accept this change.

If there is an error, you will be able to see it after you disable this setting.

Sounds like the power circuit on the motherboard could be faulty. Look for any leaking capacitor on the board, may be fixable by replacing the component. It's easier but more expensive to replace the system board.
