Tip & How-To about Computers & Internet

Laptop or computer restarts or reboots for no reason?

If your laptop or computer restarts for no appartent reason, the most common culprit is overheating. Take the following steps to address the problem:

1) Download and install CPUID's Hardware Monitor (it's free). Download from http://www.cpuid.com/hwmonitor.php, install and run at startup. Check for overheating especially when running 3d or online games.

2) Clean up the dust and lint often, at the very least once a month. Remove the laptop or computer cover, vacuum or blow compressed air all over the motherboard, expecially around the fan(s), CPU and GPU (video card).

If overheating is not the problem, you can check if a particular software or driver is causing the hung-up. Your best bet is to check the Event Viewer. To run the event viewer, folow the following steps:

A) Click start -> control panel -> performance and maintenance -> administrative Tools. Then click on the Computer Management.
B) In the console tree, click Event Viewer.
C) Click on "application errors". Any commands or errors just before the "Winlogon" will be the last commands before a restart (Winlogon is run only when the computer restarts). Check the error history to see if the same command is the conistently causing the hung-ups

Hope this helps ya'all

My Acer Aspire 5315-2122 laptop after welcome screen of windowsXp does not boot and blue screen shows ***stop:0x00000007B (0xF7a61528,0xc0000034,0x00000000,0x00000000) and does not go beyond


For BSOD follow the steps below that might can help:

Check the cables of VGA, Mouse , Printer , Scanner and Keyboard for loose coupling at the back of computer box.
Determine if you changed anything recently.
The most common cause of the Blue Screen is a recent change in your computer's settings or hardware. This is often related to new drivers getting installed or updated. Drivers are software that allow your hardware to communicate with Windows.
Check your computer's internal hardware. Sometimes, a poor connection inside the computer can cause a Blue Screen. Open your case and check to make sure that all the cables are firmly connected and that any cards are seated firmly in their sockets.
This is more difficult for laptops. You can check the hard drive and the RAM to make sure that they are connected properly. Remove the panels in the back that cover the hard drive and RAM with a small Phillips-head screwdriver. Press the components firmly into their connections. This step is not recommended due to damage in customer device risk.
Check your computer's temperature. Overheating can lead to your hardware malfunctioning. One of the most common components to overheat is the graphics card. In BIOS post test the computer shows on black screen at start up the temperature conditions of computer box. To check it customer can restart the computer and on first screen top right or left corner will show the information of temperature. If it is more than 40 celcius then it is more likely to crash the computer. Reseat the computer in a more cooler place i.e top of the table and away from the wall for venting purpose. The malfunction of processor fan can also be the reason.
Test your RAM. A common culprit in system crashes is a bad stick of RAM. When RAM fails, it causes the system to become unstable. Open the box unplug it from the Slot Remove the RAM clean it for carbon and dust particles and plug it back on make sure when you plug it back you hear the click sound.
Test your hard drive. Run the "chkdsk" function on your hard drive to scan for errors and fix potential problems. A failing hard drive can cause Blue Screens due to corrupted files. To run chkdsk, open command prompt and type CHKDSK entre.
Strip your computer down to the essentials. This is possible on desktop pcs that take out all hardware including hardisk, keyboard, mouse etc and start plugin them one by one until error comes again.

my laptop is shutting down on its own after a few hours


Hello

Thank you for using Fixya!

To address the problem at hand, we will need to look at a couple of factors. I will list them, and explain:

1. This can be a Virus which have infected the computer and automatically shuts down the computer.

2. This can be a battery problem. If the unit powers off while it is plugged into the adapter, it is not a battery problem.

3. Lastly, and most probable, it is an overheating issue. This is a very common problem with al notebooks.

Let me know some more details on the exact problem. Do you get an error message or a blue screen?

Since i stated the it is most probably an overheating issue, we can determine it by the following questions:

Does the CPU fan Spin louder(Faster) than usual?
Does the computer shut down after an approximate time each time?

If the fan runs louder than usual, it is most probably that the dust particles on the CPU fan is preventing the sufficient air flow to cool down the CPU, hence the computer shuts down to prevent damage to the CPU.

At the link below you will be directed to a page which will explain to you how to clean the CPU fan. This is now your exact model, so, if you want to attempt this, and is sure that it is an overheating problem, you can follow the steps.

Your cooling fan will either be located under the keyboard, or on the back of the notebook itself. Have a look at the links below and follow the applicable steps.

Let me know, i will gladly help.

computer keeps shutting off every five minutes or so


Computer may be shutting od due to following reasons:

Computer Virus
There are higher chances of a computer shutting down due to the interference of a computer virus. The virus gets into the computer and fiddles with crucial sections of the operating system, which may cause the system to shut down automatically. You need to install a good antivirus software and get the computer scanned thoroughly for any malware and viruses. Also see to it that the operating system and all hardware drivers are updated.

Power Supply
The computer power supply unit is an equipment that is installed in the cabinet to provide power to the system for operation. Your computer can shut down, if there is not enough power supplied to it for handling the programs running. If you are using the computer for running intensive software such as PC games, the system would require more power than what is actually available. Another reason can be overheating of the power supply. After the power supply is used for a substantial period of time, there is a possibility of dust getting collected inside it. And this may cause it to overheat, resulting in the shutdown of the desktop computer. If the power supply is at fault, you may need to get a new one installed.

Overheating of the Motherboard and the Processor
As with the case of dust getting collected in the power supply, the computer motherboard and the processor can also collect dust, which may be the reason for their overheating. This may also be one of the reasons why your computer keeps shutting down and restarting. You need to open the computer cabinet and clean the dust off the computer parts. The CPU board and the processor can also overheat because of many applications running. If this is the case, then it is suggested to keep the running of applications as less as possible or increase the size of Random Access Memory (RAM). Bad capacitors on the motherboard is also one of the reasons, why your computer keeps shutting down very often.

The 'Automatically Restart' Setting
If you are using Windows XP operating system, there is a setting that indicates the computer to reboot if it detects an error in the system's operation. In order to check if this is the problem, click on 'Start' and 'Control Panel', then select 'Performance and Maintenance'. Click on 'System', then the 'Advanced' option, and select 'Settings' from the 'Startup and Recovery' section. You will find an 'Automatically restart' option, which you need to uncheck for preventing the system from rebooting. Read more on computer keeps restarting on its own.

These were the possible reasons, why your computer keeps shutting down and rebooting. You also need to check if the power cables are properly connected to the cabinet and to the UPS, as loose connections can also be a reason for system shutdown. The most common cause of the computer getting shut down or restarted is due to overheating of the power supply and other internal computer parts.
