Question about Barebone Systems

1 Answer

My computer keeps shutting itself down without warning. I have live one care which prevents virus to pass through the system but the computer will stay on for a little while then shut off then stays on for shorter amount of time each time it is restarted.

It is possible this is caused by overheating. Check the power supply fan first, probably in the back of your computer tower. Do you feel any airflow? If so, the next thing to check would be the CPU fan/heat sink. Many motherboards have a temperature gauge software nowadays, or you can download one for free online to see how hot your CPU is running.

2 Possible solutions:

  1. Replace Power Supply if there is no air flow.
  2. Put in a new Processor Heatsink/Fan

What would keek my desktop computer from shutting down? Only thing I can think of is my cpu fan has become louder than what it used to be and continously runs from the time I turn on the computer until I...


The CPU fan is always running in all PC's - if it didn't then the CPU would over heat and the PC would crash. If the PC is not shutting down when instructed then something is preventing the operating system from carrying out the command - for example a program running in the background.
I would suggest run a virus scan first (make sure your anti virus is up to date first). Post a reply how you get on, with the results.

Resets by itself


This might be an error / fault, somewhere at the motherboard. I myself have bought 2 identical new systems years ago. They are exact copies of each other, but one started (especially when wintertime was comming) started to reboot without any indication or warning. Sometimes it happened at booting (still black DOS-screen), sometimes when Windows XP was running a few seconds, or even later. However, after 1 reboot it seldom happened the computer would reboot again.
I've swapped all components piece by piece, and noted the problem was located at the motherboard.

So far I couldn't pinpoint the exact source of the problem, but I'm 100% confident it's an electronic component-failure problem. I think it might be a thermal problem at the PCB, something like a loose contact. Maybe something like this, together with bad caps or malfuntion of MOSFETS. But it's definitly something at components-level.

My emachines hardrive keeps shutting down. It gets to the point were it says windows now loading but then it turns off. This goes on and on


Without knowing your computer knowledge, I would have to say that you should try the drive in another computer. this will give you some indication of the health of your HDD. If it works in the new location you should run a Virus/Malware scan on the drive. (Do this while still in the new location). Good luck- Hard drives are expensive at the moment.

I don't know my computer shuts down automatically.


In order to advance on the resolution path, could you please check the following :

This problem could come from a power saving mode that we see more often these days.
You must ensure that there is any setting in the BIOS that could cause the machine to shutdown ? If you want to make sure it's comes from the BIOS or from the Operating System (I suppose you use Windows), I recommend you to boot a linux live CD on a usb stick or CD. My recommendation would go to download and burn the latest Kubuntu CD, then boot on it (without installing it of course), and wait for 2 hours to check if the computer did stop or not.

Hi i have this satellite r630-155 and i think it got hit by a virus. I dont see any recovery cd with the box. How will i reformat it? Thanks!


Depending on what kind of problems the virus is causing, you have a few different options.

If the virus has only wreaked havoc on the operating system, you can reinstall it. Toshiba laptops do not come with a recovery CD. Instead, Toshiba provides a way for you to restore the computer's OS to its original factory settings through the boot menu. The details on how to do this for your make and model can be found here: http://aps2.toshiba-tro.de/kb0/HTD9102IR0000R01.htm

If the virus has somehow managed to prevent you from getting as far as the boot menu, or if the virus has destroyed the Toshiba factory settings backup, then you will need to contact Toshiba and have them replace the operating system. If you are under warranty, this will be of no cost to you.

THE SCREEN IS COUNTING DOWN AFTER TURNING IT OFF


Do a virus scan, I 've never seen a computer countdown after shutting it off. You may have a virus that once it gets to a point it may disable your computer .
You might even just go ahead and reinstall your OS before you can't do anything.
