Here I am Going to show “Top Reasons Why PC Crash”:-
The main reason why Windows crashes is hardware conflict. Each hardware device conveys or communicate to some other devices using an interrupt ask for channel (IRQ). These are allowed to be unique for each device.
For instance, a printer usually links internally on IRQ 7. The key pad usually uses IRQ 1 as well as the floppy computer drive IRQ 6. Each device attempt to hog an individual IRQ pertaining to itself.
If there are a variety of gadgets or lots of devices, or whenever they are not properly installed, two of these may end up sharing the same IRQ number variety. When the consumer/end user tries to make use of both devices at the same time, a crash happens. The solution to check but if your computer carries a hardware conflict is through the following course:
Start->Control Panel->System and security-> system->Device Manager
Usually if the device has a problem some sort of yellow-colored ‘!’ appears next to its description in the Device Manager. Highlight Laptop or computer (in these devices Manager) along with click on Properties to discover the particular IRQ numeric value used by your personal computer. If the IRQ number seems two times, a couple device might be using it.
Sometimes a device may share an IRQ with something described as ‘IRQ holder for PCI steering”. This really is ignored. The easiest method to correct this error is to remove the problem device and re-install it.
Most of times you may have to find more recent drivers on the web/internet to to make the device function properly. A great resource is online world www.driverguide.com. If the product is often a soundcard, or maybe a modem, the item is usually predetermined by simply moving the item to a different position within the motherboard (be careful about cracking open your personal computer, since you may gap the particular warranty).
After doing work inside a computer you should switch it off, unplug the particular mains leads along with touch a great unpainted material surface to l to discharge any static electricity.
As we know each and every motherboard is supplied with a range of chipset settings that are decided in the factory.a most common and simple way to access these settings is to hit the F2 or delete button during the starting of booting process.
Once inside the BIOS, excellent care should be taken. It is a great way to write down all the settings that appear on the screen on Note-paper. suppose in future, you change something and the computer becomes more unstable, that time you will simply revert that setting according to that note.
Microsoft Windows is better in allocating IRQ numeric values than any other BIOS. If you can then set the IRQ numbers to Auto in the BIOS. This will allow Windows to allocate the IRQ numbers (make sure the BIOS setting for Plug and Play OS is switched to ‘yes’ to allow Windows to do this.).
RAM stands for Random-Access-Memory most of time problems because of the blue screen of death with a message saying that Fatal Exception Error occured.As we all know that A fatal error indicates a serious hardware and it configration problem . Lots of times that problem is that much dangerous, we don’t remain another option to replacing that hardware device.
But a fatal error caused because of Random acces Memmory might be caused by a mismatch of chips. For example, mixing 70-nanosecond (70ns) Ram with 60ns Ram will usually force the computer to run all the Ram at the slower speed. This will result in to crash the machine if the Ram is overworked.
It solution to problem is to enter the BIOS settings and increase the wait state of the Ram. This can make it more stable. Another way to troubleshoot a suspected Ram problem is to rearrange the Ram chips on the motherboard, or take some of them out. Then try to repeat the circumstances that caused the crash. When handling Ram try not to touch the gold connections, as they can be easily damaged.
Hard Disk Drives:-
As a time goes, the data on a hard disk drive starts to become fragmented.To avoide this problem, best solution is defragment the hard disk every week or so, to prevent the disk from causing a screen freeze. Go to
Start->Programs->Accessories->System Tools->Disk Defragmenter
That will start the procedure.After that You will be unable to write data to the hard drive (to save it) during the disk is defragmenting, so it is a great idea to schedule the procedure for a period of inactivity using the Task Scheduler.
The Task Scheduler should be one of the small icons on the bottom right of the Windows opening page (the desktop).
Some lockups and screen freezes caused by hard disk problems can be solved by reducing the read-ahead optimisation. This can be adjusted by going to
Start->Settings->Control Panel->System Icon->Performance->File System-Hard Disk
As we all know hard disks will slow down day by day and crash one day if they are too much full. so try to minimise or backup data to another memmary and free some space on it.Also fond out temparary files on c drive by type in command prompt %temp% and then hit enter button you will get folder with lots of files, delete it. Deleting the contents can free a lot of memmory.
Flush out Recycle Bin every week to free more and memmory. Hard disk drives should be scanned every week for errors or bad sectors. Go to
if you are not able to do that then simply assign the Task Scheduler to perform this operation at night when the computer is not in use.
Most of viruses erase or clean the boot sector of a hard drive,so that we cann’t start our system. This is why it is a good idea to create a Windows start-up disk. Go to
Start->Settings->Control Panel->Add/Remove Programs
Here, see for the Start Up Disk tab. Virus protection requires constant vigilance.
A virus scanner look for lots of virus signatures in order to be able to identify viruses and all that list of signatures are stored in a DAT file.So that we always need to upade that DAT files weekly from the website of your antivirus software manufacturer.
printers are external devices. Action of sending a document to print, that creates a big file, which nis known as postscript file.
Printers don’t have large memmory.It has only a small amount of memory area, known as a buffer. and so this can be easily overloaded. Printing a document also uses a considerable amount of CPU power. This will also slow down the computer’s performance.
It is biggest problem of computer crash as faulty or badly-installed software. That problem can be cured simply by uninstalling the software and then properly reinstalling it.
Computer System Registry can be corrupted by old or deleted references to obsolete software that you thought was uninstalled.So what we need to do is- Use Reg Cleaner by Jouni Vuorio to clean up the System Registry and remove obsolete entries.
In windows Safe Mode is best way to resolved problems. That can be done while start-up. When you see the message “Starting Windows” press F4. This should take you into Safe Mode.
Safe Mode is best to resolved problems because it loads a minimum of drivers. It allows you to find and fix problems that prevent Windows from loading properly.
Central processing units (CPUs) are attached or embedded with fans to keep them cool. If the fan fails or if the CPU gets old it may leads to overheat and that will result into particular kind of error known as kernel error. This is a common problem in chips that have been overclocked to operate at higher speeds than they are supposed to.
So solution is that get a bigger better fan and try to install it on top of the Central processing units.
Power supply problems:-
Computer system always require steady electricity supply. A power surge or spike can crash a computer as easily as a power cut. This problem will solved using UPS. buy a uninterrupted power supply (UPS). This will give you a clean power supply when there is electricity, and it will give you a few minutes to perform a controlled shutdown in case of a power cut.
