10 reasons why the computer freezes
10 reasons PC Crash U should know
Fatal error: The system has become unstable or is busy, "he said." Enter to return to Windows or press Ctrl-Alt-Del to restart the computer. If you do this, you will lose all stored information in all open applications. "
You just been beaten by the Blue Screen Death. Anyone who uses Windows Mcft be familiar with it. What can you do? More importantly, how can – if you let this happen?
1 Hardware conflict
The first reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through a channel interrupt (IRQ). They are supposed to be unique for each device.
For example, a printer is connected internally usually on IRQ 7. The keyboard usually uses IRQ 1 and the disk drive IRQ 6. Each device will try to hog a single IRQ for itself.
If many devices, or if not are properly installed, two of them end from May to share the same IRQ number. When the user tries to use two devices at the same time, accidents can occur. The way to check if your computer has a hardware conflict is through the following route:
* Start-Settings-Control Panel-System-Administrator Device.
Often if a device has a problem with a yellow "!" Appears next to its description in the Device Manager. Highlight computer (in the Device Manager) and click Properties to see the IRQ numbers used by the team. If the IRQ number appears twice, two devices for its use in May.
Sometimes a device can share an IRQ with something described as' IRQ holder for PCI steering. This can be ignored. The best way to solve this problem is to remove the problem device and reinstall.
Sometimes you can find newer drivers on the Internet to operate the device correctly. A good resource is www.driverguide.com. If the device is a sound card or modem, can often be fixed by moving to a different location on the plate base (Be careful when opening the computer, as you may void the warranty).
When working on a computer, please disable disconnect the power cord and touch the unpainted metal surface to discharge static electricity.
CTFM To be fair, the problem with IRQ numbers is not their creation. It is an inherited problem back to the first computer chip designs using the IBM 8086. Initially there were only eight IRQs. Today there are 16 IRQs in a PC. It's easy to get lost les. It is planned to increase the number of IRQs in future designs.
2 Bad Ram
RAM (Random-Access Memory) problems can bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes May is: one part is damaged and must be replaced.
But a fatal error caused by Ram could be caused by a mismatch chips. For example, mixing 70-nanosecond (70ns) Ram with 60ns Ram generally force the computer to perform any RAM to the slower speed. This often will hang the machine if the Ram is overworked.
One way to avoid this problem is to enter the BIOS settings and increase the waiting time of the Ram. This may make it more stable. Another way of solving a suspected Ram problem is to rearrange the RAM chips on the motherboard, or drink. Then try to repeat the circumstances that caused the accident. When handling Ram try not Touch It gold connections, as they can be easily damaged.
Parity error messages also refer to Ram. Modern RAM chips are parity (ECC) or parity-profit (non-ECC). It is preferable not to mix the two types, as this may be a cause problem.
EMM386 error messages refer to memory problems, but can not connect to bad RAM. This may be due to free memory problems often linked to old Dos-based programs.
3 BIOS settings
Every motherboard comes with a range of options chipset, which is made in the factory. A common way to access these settings is to assist in the F2 or delete button during the first few seconds of a boot.
Once in the BIOS, care must be taken. It's a good idea to write on a sheet of paper all the options that appear in the screen. In this way, if you change something and your computer becomes more unstable, you know what adjustments to return.
A common BIOS error concerns the CAS latency. It is the Ram. Older EDO (Extended Data a) Ram has a CAS latency of 3. Newer SDRAM has a CAS latency of 2. Setting the wrong figure can cause the Ram to lock and freeze computer screen.
Mcft Windows is better at allocating IRQ numbers than any BIOS. If possible, set the IRQ numbers to Auto in the BIOS. This will allow Windows to allocate the IRQ numbers (make sure the BIOS settings for Plug and Play OS is spent to "yes" to allow Windows do it.).
4 hard drives
After a few weeks, information on the hard drive begins to be partial or fragmented. It's a good idea to defragment the hard drive every week to keep the disk causing a screen freeze. Jump to
* Start-Programs-Accessories-Tools System, Disk Defragmenter
This will start the procedure. It will be impossible to write data to disk (for the record), while the defragmentation disk is, what is a good idea to schedule the procedure for a period of inactivity using the Task Scheduler.
The planner should be a small icon on the bottom right of the homepage of Windows (the desktop).
Some crashes and screen freezes due to drive problems can be solved by reducing the prefetch optimization. This can be adjusted by going to
* Start-Settings-Control Panel-System Icon Panel performance file system hard disk.
Hard drives are slow and crash if they are too full. Make some hard drive home every month and free space on it. Open the Windows folder on drive C: and then locate the Temporary Internet Files folder. Delete the contents (not the folder) can free up much space.
Empty Trash recycling every week to free more space. Hard drives should be scanned every week for errors or bad sectors. Jump to
* Start-Programs-Accessories-Tools system-Scandisk
Programmer Otherwise assign tasks to perform this operation at night when the computer is not used.
Fatal exception OE 5 and VXD errors
Fatal exception errors in OE and VXD errors are often caused by video card problems.
These can often be resolved easily reduce the resolution of the video screen. Jump to
* Start-Settings-Control Panel-Display Settings
Here you should slide the bar area of the screen to the left. Take a look at the color setting to the left of this window. For most computers desktop color depth of 16 bits is adequate.
If the screen freezes or you experience system errors, which may be due to the road video. Make sure there is no hardware conflict. Jump to
* Start-Settings-Control Panel-System-Device Manager
Then select the + beside Display Adapter. A line of text describing your video card should appear. Select (and Blue) and press properties. Then select the resources and select each line in the window. Find a message that says there is no conflict.
If you have a hardware conflict on the video card, see here. Pay attention to this and take notes on what to do if things worse.
How to resolve a hardware conflict is to disable automatic settings and click the Change Settings button. Looking for a setting that displays a message that no conflict.
Another useful way to resolve video problems is to go to
* Start-Settings-Control Panel-System-Performance-Graphics
Here you must move the slider Hardware acceleration on the left. The drivers, as always, the most common cause of problems related to graphics cards is old or defective (a driver is a small piece of software used by a computer to communicate with a device).
Consult the manufacturer of your video card on the Internet and search for drivers most recent to do so.
6 virus
Often the first sign of a virus infection is instability. Some viruses delete the boot sector of a hard disk, making it impossible to start. Therefore, it is a good idea to create a Windows boot disk. Jump to
* Start-Settings-Control Panel-Add/Remove Programs
Then locate the Startup Disk tab. Virus protection requires constant vigilance.
A detector virus requires a list of virus signatures in order to be able to identify viruses. These signatures are stored in a DAT file. DAT files should be updated weekly on page website of your antivirus software manufacturer.
A good antivirus program is McAfee VirusScan by Network Associates (www.nai.com). Another is Norton AntiVirus 2000, made by Symantec (www.symantec.com).
7 printers
The action of sending a document to print creates a bigger file, often called a PostScript file.
The printers are only a small amount of memory, called buffer. This can be easily overloaded. Print of a document also uses a considerable amount of CPU power. This will also slow computer performance.
If the printer try to print characters strangers, they may not be recognized and may cause the computer. Sometimes printers will not recover from a crash because of confusion in the buffer. A good way emptying the buffer is to unplug the printer for ten seconds. Booting from a powerless state, also called a cold boot, will restore the default printer and you may be able to practice.
8 Software
A common cause of computer crash is faulty or incorrectly installed software. Often the problem can be cured by uninstalling then reinstall the software. Use Norton Uninstall or Uninstall Shield to remove an application from your system correctly. Also remove references to the program in the System Registry and leaves the way open for a new copy.
The system registry may be damaged by references the old obsolete software that you thought was uninstalled. Use Reg Cleaner by Jouni Vuorio to clean the system registry and remove obsolete entries. It Runs on Windows 95, Windows 98, Windows 98 SE (Second Edition), Windows Millennium Edition (ME), NT4 and Windows 2000.
Read instructions carefully and use it to not cause permanent damage to the registry. If the registry is damaged, you must reinstall the operating system. Reg Cleaner can be obtained from www.jv16.org
Often, Windows problem can be resolved by entering Safe Mode. This can be done at startup. When you see the "Starting Windows" and press F4. This should take in safe mode.
Load Failure Mode of a minimum of drivers. Allows you to find and fix problems that prevent Windows from loading properly.
A Sometimes installing Windows is difficult due to improper BIOS settings. SUWIN If you receive error messages (Windows installation) during installation Windows, then try entering the BIOS and disabling the internal CPU cache. Try to disable the Level 2 (L2), if this fails.
Remember to restore all BIOS settings to their previous settings after installation.
9 Overheating
Units Central (UC) are usually equipped with fans to keep cool. If the fan fails or if the processor is old can begin to overheat and produce a particular type of error called a kernel error. This is a common problem in chips overclocked to operate at higher speeds than they are supposed to.
One solution is to get a wider range of better quality and installed on the top of the CPU. Fans Specialist / radiators are available in www.computernerd.com or www.coolit.com
The CPU problems can often be fixed by disabling the internal CPU cache in the BIOS. This will make the machine run more slowly, but also should be more stable.
10 problems of supply energy
With all the new buildings around the country, the regular supply of electricity has become disrupted. A or maximum voltage can be the crash of a computer as easily as a power outage.
If this became a nuisance for you then think about buying Uninterruptible Power System Power (UPS). This will give you a clean power supply when the power fails, and give a few minutes to complete a controlled stop in case of power failure.
It is a good investment if the data is crucial, because a power failure causes the saved data to lose.
