My Dell inspiron 1150 switches off very often by itself. Can anyone help?

The main reasons for restarts: 1.bad memory 2.overheating (can either be processor or chipset)   Yours sounds as if it's your processor overheating, though, since it's usually happening when you're using your processor at or near 100% usage.  \n\nTry turning it on, then going into the BIOS, and check your temps there.  If it's idling much above 50°C in the BIOS, then that's almost surely your problem.  More than likely, you just need to go to Wal-Mart, and buy a can of compressed air, and blow all of the dust out of your heatsink.

There many possibilities, hardware conflict, system over heating, software conflict etc.  try cleaning out the computer with a can of compressed air and monitor your system temp, that would be the simple place to start, if that doesn't work IM e and we can go deeper into the issue.\n\nThat should be worth 10 points

Dell techs are stupid and when ever they cant come up with anything else they automatically say the motherboard is out. I would reccommend going to a computer place and having them check it out. I called on mine one day and she went though like 3 things, and decided it had to be the motherboard...when actually it was just the battery.

Your screen has gone to standby to save power, just wiggle the mouse or click. and it should come back. You go into your computer options and change the preferences so it will not do this as much or not art all

try clicking altogether ctrl+alt+delete and click shut down. if it's still not working, you have to contact your pc manufacturer

the computer turns off, because you might be eitehr using MS windows 2000 or MS Windows XP service pack 1 which had lot of errors. USe MS_windows XP Service PAck 2 for the computer to run better. Hope it solves your problem, enjoy.

You should have posted he Make and Model. Some Laptops have design flaws. If the air vents are at the bottem of the pc try blowing the dust out and see what happens. you could try some compressed air but don't spray too much at once.\n\nSome Dells like my friends have a minor bug with thier power management feature sets which can be corrected by upgrading to the latest BIOS or other. In my friends case it only showed up when the internal heatsink collected a large amount of dust. \n\nOther laptops could possibly have a similar flaw. My friends problem started after 6 months also a 3 GHz Laptop. you can message me and and i'll give you the exact instruction on where to go and what to download, if it's a DELL.

try CPU (processor) cooler there is an sensor under the cpu socket on the mainboard so when the cpu gets hot it turn`s off the pc and wont turn it back on until it gets cooled down,since you power it manualy

Goto your CONTROL PANEL and select POWER OPTIONS.  Make sure it is set at a level you want, I assume it says to turn off hard disk after 20 mins...Just change that to NEVER.

you mayhave a hardware iwwue with the video inverter.  If it's a dell run the 32 bit diagnostics.  The first part will tell you if you have an inverter issue.  If you do then contact the manufactruer if your under warentee.

Two things I would first check, \n1. Make sure the reset button is not stuck.\n2. Make sure your BIOS does not have the "Wake on LAN" feature turn on, especially if you have DSL, or Cable Internet.

try going to control panel and then performance and maintenance and then power options. there's settings here that prolong the life of the battery so try changing your power scheme if it's set for max battery maybe?

Are you overclocking it? if so, stop. If not, check to make sure the fan is functioning properly. If it's not, and it's still under warranty, contact dell and get em to fix it. If it's not under warranty, a quick solution is to have a large fan blowing on it. Then, consider replacing the fan entirely.

You need to enable Advanced Power Management in the bios setup. \nTry the link below for details.

Its prob the power supply. Does  the fan turn on ???\nYou might want to replace it ( $ 60 ) . Also make sure that the power button is on . On the back of your computer theres a little button . \n\nAlso check out my free computer articals at http://www.cityredding.com/computerhelp

Common problem with the Dells.  It is caused by the build in "mouse" stick or touchpad shorting.  As it is a short, there is no key combination that will stop it.  It keeps moving until the short stops.  There is no way to fix or clean one that we have ever found.   We replace the keyboards and the palm rest.\n\nI support a site with about 1400 Dell laptops, and we normally replace 2-3 keyboards and touchpad units every week for just that issue.  We get boxes of 25 at a time. Fortunately, ours are under warranty.\n\n If your laptop is still under warranty, contact Dell to have it repaired.

Yes,sounds like over-heating of the power supply unit.It was switching itself off every time it got over-heated.Most probably the cooling fan inside the power unit was not working.
