A fatal error will cause the system to become unstable or busy. Your Windows PC will often display the Blue Screen of Death (BSOD). Do you experience it often?
A computer that often crashes is quite annoying for all users, especially when you are doing important work or are busy playing games. When the computer crashes, for the most part, the computer displays the Blue Screen of Death (BSOD), the system cannot be started, the screen freezes without response, the mouse and keyboard cannot enter input, and the software operation is abnormally interrupted.
If you often experience this, read the following full article. In this article, Bardimin will explain the causes of Windows PC crashing in detail. By knowing the cause, you will be easy to fix it.
1] Hardware conflicts
The number one cause of Windows crashing is a hardware conflict. Each hardware device communicates with other devices through an interrupt request channel (IRQ). These channels should be unique for each device.
For example, printers are usually connected internally on IRQ 7 and keyboards usually use IRQ 1. Each device will try to monopolize one IRQ for itself.
If there are many devices, or if they are not installed properly, the devices may use the same IRQ number. When a user tries to use both devices at the same time, a crash may occur.
The way to check if your computer has a hardware conflict is through the “Device Manager”.
- Open the “Device Manager”. You can open it by using the (WIN + R) button. Then in the “Run” dialog box that opens, type “devmgmt.msc” and press the Enter key.
- Select the “View > Resources by connection” menu.
- Double-click on “Interrupt request (IRQ)” to expand and view the detailed information.
For example, the IRQ number is indicated by the text “0x00000001(01)” which indicates the IRQ number 01 for the keyboard. If the IRQ number appears twice, two devices are using the same number.
Sometimes devices may share an IRQ with something described as an “IRQ holder for PCI steering”. This can be ignored. The best way to fix this problem is to remove the problematic device and plug it back in.
Some devices can be fixed by moving them to different slots on the motherboard.
2] Poor RAM
RAM (Random Access Memory) problems can cause a Blue Screen of Death (BSOD) with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes this means that a component is damaged and needs to be replaced.
But this fatal error can be caused by chip incompatibility. For example, mixing 70 nanoseconds (70ns) of RAM with 60ns of RAM will usually force the computer to run all of the RAM at a slower speed. This will often damage the machine if the RAM is overworked.
One way to solve this problem is to go into BIOS settings and increase the waiting status of RAM. This can make it more stable. Another way to solve RAM problems is to only use RAM with the same chip (not using RAM with different chips).
The parity error message also refers to RAM. Modern Ram chips can be either parity (ECC) or non-parity (non-ECC). It’s best not to mix the two types, as they can cause problems.
