My computer shuts down and I can't it to come back up, what could be causing it.?

Every time it is idle for any period of time it will shut down. I run Windows XP and Norton Security. Both have been updated.

Check your electricity in your home or place. That was the cause of my computer doing that. Also you could still have a virus. Do you have DSL? If so and you are still using other things like Norton that could also be a problem. The DSL folks have to protect you. You could have too MUCH protection believe it or not. That was also causing shut downs for me.

Hope this helps.

Hi. Shutdowns are sometimes caused by excessive heat. Check your CPU fan and heatsink for dust and make sure you have adequate case ventilation.
Control panel. click on power icon and look were it says 20 minutes to shut down change it to never then click apply.
Sounds to me like you need to change your settings--a computer can be set up to hibernate or turn off after so many minutes of idle time. If that doesnt work try your system restore-to an earlier date when it did what you wanted it to.
yeah, the heat may cause that.. and it also can mean that you're about to loose everything, so you'd better start making a backup of your files...

'cause when it happened with my, everytime it turned off, i started it over again... than one day my computer broke and i lost everything (a motherboard problem, wich might have been avoided).

so i recommend you consider making a backup of your files as soon as possible... it's a risk you might take!

but if you can, take you computer to some tecnic.
