Possibly it may be due to virus that is infected to your system.
try installing new antivirus (Avast,Norton) and scan your system.

My acer all in one z5600 runs for awhile and then shuts down very annoying!!!


Start by cleaning the fan or fans, heatsink, and vents, you may have to open the computer. When you open, you may as well replace the Thermal Paste on the CPU and Graphics Chips. Overheating will cause shut downs, heat sensors set to detect a set temp. will shut down to protect vital components from heat related damage. ALSO, Open Control Panel, Power Options, set to High Performance, open Change plan settings, under Plugged In, set both to Never, open Advanced Power settings, go through thr Advanced settings set Sleep and Hibernate to Never, Adjust to your preference. It's a good idea to Always shut down your computer when not in use, it will last longer and a reboot everyday will reset the machine. Make sure ALL your Windows and Acer Updates are current.

ACER ASPIRE X1200 Unexpected Shutdown


When does it shut down? Are you able to use it at all? Or does it shut down when you are trying to boot it up?

When it shuts down are you able to boot it right back up and start using it? If not, it might be running hot. If you let it sit a while to cool off then try booting and if you are successful, then it is definitely running hot.

Three things that will make a computer run hot.
1. Dust - Dust inside the computer, dust clogging the vents and fans. Dust around the cpu and heat sink. To fix, Remove the power cord, remove the case and take a can of compress air to blow out the dust.

2. A fan is not working. Make sure the fan inside the Power supply and the fan that sits on top of the cpu is working. Normally the system will notify you if the fan is not working. To fix, you will have to replace a fan that is not working.

3. The Thermal Paste around the CPU and Heat Sink has dried up or is too thin to keep the unit cool. To fix, apply a fresh coat of Thermal Paste around the cpu and heat sink.

Maybe you have a virus or infection that is shutting you down if it is not running hot and you are allowed to work on the computer for a while before it shuts down. Boot the System in Safe Mode and see if it shuts down.

Turn off the computer, then hit the power button to turn it back on and immediately start hitting the F8 key repeatedly until you see SAFE MODE. Take the Safe Mode With Networking option (this will give you internet connectivity) and let it boot up. Safe Mode will look different to you, the screen will be darker and the icons bigger, this is normal. Download and install MalwareBytes and 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.

Computer shutting off


shutting off when? Shutting off immediately when you try to start it? Shutting off after it has run for a while?

If it is shutting off after it has run for a while, then it is probably running hot. If you try to restart it immediately it will not boot. If you let it cool off for a while then it will boot successfully (definitely a sign of running hot).

Things that make a computer run hot:
1) Dust in the vents, fans, cpu & heat sink and all inside the computer.
2) Fan not working
3) The Thermal Paste on the cpu and heat sink has either dried up or is too thin to keep it cool.

If it shuts down immediately after it has been sitting for a while then it's not running not and your system has some other problem.

When I plug the unit into power, the CPU fan runs very fast but no boot, and then when I press power on the fan slows down and the PC boots normally. It shuts down in about 30 minutes with no sign of...


Sounds like you are overheating. One way to tell if it's overheating is you say it will run for about 30 minutes then shuts down. When it shuts down try rebooting to see if the boots successfully. If it fails to boot successfully right after it shut down then you are probably overheating. If you wait awhile to let it cool down for 30 minutes or so and if you reboot and it does it successfully you definitely have a overheating problem. If I remember correctly all those compaq sr series have loud and fast running fans. Computers overheat because of three reasons for the most part: 1) A fan has stopped working. 2) The Thermal Paste on the CPU and Heat Sink has dried up or is not thick enough to keep the unit cool. 3) Dust has clogged the fan vents and inside the computer. Fortunately for you desktops don't have to be completely disassembled like laptops to get to the fan, CPU and heatsink. Just pop the case and you'll see the components attached to the motherboard

SYSTEM TRIES TO COME ON BUT ONLY MAKES IT TO THE CONFIGURING SCREEN THEN IT SHUTS ITSELF BACK DOWN, THIS IS CONTINUOUS. I have a Dell Inspiron 531. Please advise. Thank you, Candace


It sounds like it could be a problem with overheating, which is causing the machine to turn itself off. Try opening the side cover, and carefully cleaning the motherboard and especially the CPU fan - which is the large fan probably on top of a silver box with loads of fins on it. Carefully remove the dust, and see if this clears up the problem. It may be worth removing and refitting the memory whilst the computer is open, to reduce the problems of bad connections between the cards.

If it doesn't fix it, then reply here with any error messages that pop up on the screen.

Dell Inspiron 530 randomly shuts down and restarts


Sounds like it could be a virus. Or, a heat buildup problem - are all fans inside machine working? Is the fan inside the power supply operating? Was there any work done inside the computer recently?
If the hdw is all ok, go out and buy yourself a copy of Norton Internet Security 2009 - 1 user lic - $49.99 @ Staples. Do *not* buy any earlier vers. of this software! Install, update it, run computer computer scan - probably will find/remove some/many viruses.

If this helps, please take the time to rate my response to you.
Thanks and good luck.

CPU fan not running?


If the fan isn't running, the computer probably shut itself down because it overheated. Check to make sure the cable going from the fan to the motherboard is securely plugged in. If it is and the fan still doesn't run, you have a faulty fan and need to replace it before you start up your computer again. It's not good to run a computer that hot.
Please rate, thanks!

Hp pavilion desktop a220n


check the fan (top rear of the computer) , make sure it runs when you start the computer. if it is NOT running the power supply may be the cause.
also you may need to remove the case and inspect the fans inside. you shoulkd be able to remove a couple phillips head screws on the back of the computer and lift the cover off or at least the side making the guts of thhe computer visible.
once open , inspect all the fans and cables, especially the fan on the main board and the metal piece with fins undernieth it, this tends to collect dust causing the cpu below to overheat and shut down the syatem to protect itself. The number one cause of crashes is overheating.
look at these things to start and post your findings and we'll move on to another step.
