Computer shuts off when my mom plays facebook apps?

It never shuts off unless she's playing a facebook app. Using vista, Dell inspiron.

MAYBE your hard disk space or RAM has low space left..

I bet its that farmville, that application takes up way too many cpu resources. You ll probably need more ram for your machine.

Aside from the obvious questions about whether or not you have done a virus scan and done a search for trojans and stuff with Yahoo Anti-Spy there is only one really important question.
When is the last time you updated the PC?
The updates should have solved some of these issues. This sounds to me like a graphics issue if the Application is coming on and crashing the PC it may be related to the video, maybe.
It may also be a hardware issue where the PC is over taxed as the CPU is overused and it is struggling to keep up.

There is one thing that I would suggest and that would be do your disk cleanup, defragment, run virus scanner, do your Anti-Spy and then go to Windows Update and see what the offer you as an update.

Face book has already been at the center of a debate saying there are issues on their site that are not safe and they may have a viral leak and a rogue group of hackers inserting messed up applications into their site.

Shutting off though.... That has to be a hardware or software issue seriously if you aren't capable of handling this take it to a tech.

Determine whether you are using Windows 7 or Windows Vista. Windows 7 users can simply click on the "Windows Start Button" and then go to the "Run" link. Once run pops up type in "CMD" and hit enter which will cause the MS DOS prompt to appear. Type in "CHKDSK /r" which will check for hard disk errors. Vista users need to click on "Start" then go to "Accessories" followed by "System Tools" and then run the MSDOS program followed by "CHKDSK /r"

Insert your restore CD if errors are found and not fixed by the check disk function listed above. Turn your computer off and then back on. You'll be asked to hit any button to boot from your CD; press any key. You will then be asked if you want to install a fresh version of your OS or "Repair" a current copy. Choose the "Repair" option and allow the computer to go through the necessary steps.

After the repair function has run, turn your computer off and then back on. Wait and see if the computer shuts down again. If it does not shut down, your computer's restore function has fixed the file, which was probably caused by a bad system file.

In additional to this there could be Virus issue of some power supply malfunctioning…
