Computer or Laptop Repair – 7 Reasons Why your PC Crashes

Are you facing sudden crash problem in your laptop or computer? Do you want to know the actual reason why your system crashes? If yes, then here is the information which you are looking for.

  • Hardware conflict: Hardware confliction is the main reason of pc or laptop crash. As you know, each hardware device communicates to other devices by an interrupt request channel (IRQ) and these are supposed to be unique for each device. When there are lots of devices and some of them may not be installed properly, two of them may end up sharing the same IRQ number. So when you will try to use both devices at the same time, you will face a crash problem.
  • Bad Ram: Bad ram is one of the most common reasons of system crash. It will bring a blue screen with a message saying Fatal Exception Error on your system. Fatal error means a serious hardware problem, or a part of your computer is damaged and need replacement. A fatal error may occur due to mismatch of chips. For example, if you will mix (70ns) Ram with 60ns, then you will force your computer to run the entire Ram at the slower speed. It will results in system crash.
  • BIOS settings: A common BIOS error mainly concerns to the CAS latency which refers to the Ram. Older EDO Ram has a CAS latency of 3. Newer SDRam has a CAS latency of 2. If you will set the wrong figure your system Ram may lock and can freeze the computer’s display.
  • Virus: Virus is one of the top reasons of computer or laptop crash. Due to the infection of virus you may lose important business data within a few seconds. Some of the viruses erase the boot sector of a hard drive, making it impossible to start.
  • Software: Another reason of system crash is faulty or badly-installed software. But don’t worry you can handle it without the help of any expert computer repair services. Just uninstall that software from control panel and reinstall it again.
  • Overheating: Overheating is another common problem of computer crashing. As you know (CPUs) are usually equipped with fans to keep them cool. When these fans fail to do their work due to any reason your system will start to overheat and will generate a particular kind of error called a kernel error.
  • Power supply problems: You may face computer crash problem due to power supply problem. A power spike can crash a computer as easily as a power cut.
