In today's article we are going to learn about one important topic which normally worry computer user, sometimes you will be using your computer and all you could see on the screen is a blue screen with a pop up message like below
"Your Pc run into a problem and needs to restart.we're just collecting some error info,and then we'ill restart to you.(0% complete)"
Fatal error: the system has become unstable or is busy," it says. "Enter to return to Windows or press Control-Alt-Delete to restart your computer. If you do this you will lose any unsaved information in all open applications."
You have just been struck by the Blue Screen of Death. Anyone who uses Microsoft Windows will be familiar with this. What can you do? More importantly, how can you prevent it from happening?
Five 5 Reasons Why PC Crash
1. Hardware conflict:
Start->Settings->Control Panel->System->Device Manager.
Sometimes you may have to find more recent drivers on the internet to make the device function properly. A good resource is www.driverguide.com. If the device is a sound-card, or a modem, it can often be fixed by moving it to a different slot on the motherboard (be careful about opening your computer, as you may void the warranty).When working inside a computer you should switch it off, unplug the mains lead and touch an unpainted metal surface to discharge any static electricity.To be fair to Microsoft, the problem with IRQ numbers is not of its making. It is a legacy problem going back to the first PC designs using the IBM 8086 chip. Initially there were only eight IRQs. Today there are 16 IRQs in a PC. It is easy to run out of them. There are plans to increase the number of IRQs in future designs.
2. Bad Ram
One way around this 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.Parity error messages also refer to Ram. Modern Ram chips are either parity (ECC) or non parity (non-ECC). It is best not to mix the two types, as this can be a cause of trouble. EMM386 error messages refer to memory problems but may not be connected to bad Ram. This may be due to free memory problems often linked to old Dos-based programmers.
3. BIOS settings
A common BIOS error concerns the CAS latency. This refers to the Ram. Older EDO (extended data out) 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 up and freeze the computer's display. Microsoft 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 setting for Plug and Play OS is switched to 'yes' to allow Windows to do this.).
4. Hard disk drives
Some lockups and screen freezes caused by hard disk problems can be solved by reducing the read-ahead optimization. This can be adjusted by going to
Start->Settings->Control Panel->System Icon->Performance->File System->Hard Disk.
Hard disks will slow down and crash if they are too full. Do some housekeeping on your hard drive every few months and free some space on it. Open the Windows folder on the C drive and find the Temporary Internet Files folder. Deleting the contents (not the folder) can free a lot of space.Empty the Recycle Bin every week to free more space. Hard disk drives should be scanned every week for errors or bad sectors. Go to
Start->Programs->Accessories->System Tools->Scan Disk
Otherwise assign the Task Scheduler to perform this operation at night when the computer is not in use.
