There are so many reasons that could cause computers to crash down. Here are some common ones:
1. Computer Overheating
CPU as the core of a computer naturally produces heat while carrying out algorithms and processing data. Although computers are designed with heat dispersion in mind, we may still under certain circumstances suffer from overheating problems like random shutdowns, blue screens or freezes.
As part of the PC’s own cooling system, the motherboard can instruct components to shut down as a fail-safe if it fails to bring the temperature down. Another annoying problem that caused by overheating is the noise produced by the ventilation fans as they try desperately to do their job, which is keeping the whole system cool.
Generally speaking, the CPU idle temperature (computer idling at Windows desktop not doing any processing) is within 50°C. When handling demanding tasks, the normal temperature should be around 50-60°C. The max temperature, which is the highest safe temperature recommended by manufacturers is around 70°C. Most CPUs will begin to automatically downscale frequency once they hit 95 to 105°C. If temperatures rise further, the CPU will shut itself down to avoid permanent damage. These temperatures may vary a little, depending on your CUP brand and type.
If your computer is overheating, open up the case and check if there is any dust that's been clogging up the ventilation fans. Ambient room temperatures can affect CPU temps by 5 to 10°C. So it is very important that you keep your computer in places with proper air flow, especially on summer days when the heat builds up more quickly.
2. Dying Hard Disk Drives
Hard disk drives with their relatively low price and huge storage capacity remain the most popular storage devices out there. As the media where your operating system and application data are stored, dying hard disk drives may pose dire threats to your data safety and computer performance stability.
Under normal working conditions, hard disk drives make clicking sound every now and then. The read/write head of a hard disk drive is mounted on the actuator arm and moves back and forth to access files across sectors of the platter. Different models of HDD make different clicking sounds and if your HDD has been making clicking sounds and appears to be functioning correctly then these clicking sound may be the natural working sound of your drive.
However, if you are experiencing random crashes and freezes and the hard disk drive is making loud clicking sounds, you should be concerned that the hard disk drive could be dead at any time. After finding your hard drive is making an unusual clicking noise, you should stop using it immediately, except for necessary operations to backup and, if it has stopped working, salvage data.
3. RAM Issues
Bad RAM is to blame for many blue screens and failed boots. Before we make the decision to swap RAMs, we can first make a quick and free test via Windows to determine whether the RAMs are failing and which one is the root of the failure.
Open your Start menu and type in mdsched.exe, then press enter. You can choose to restart your computer to check RAM now or choose to check the next time you boot the computer. Once the computer starts the testing progress, it will load a screen that shows the progress and number of passes. Check the diagnostic tool for any errors. If you spot errors, it's time to test the individual RAM one at a time till you nail down the faulty one. If there are no errors, then it's likely that your RAM is not causing any issues, and you should investigate issues.
4. Corrupted Boot Section
Master boot record (MBR) is essential for booting. It holds the information on how the logical partitions, containing file systems, are organized on that medium. Many destructive viruses damage the Master Boot Record and make it impossible to start the computer from the hard disk. For example, the CIH variant would target and attack BIOS and sabotage partition table in the process. Shutting down the computer while dividing partitions or converting filesystems may lead to MBR damage.
We can use the Bootrec.exe in Windows recovery environment to repair, fix or rebuild the MBR. Fixing the MBR and other boot problems in Windows requires installation disk or recovery disk to enter the recovery environment. Once you are in the recovery environment, you can access the Command Prompt to try to fix the MBR. Enter the following commands:
bootrec /RebuildBcd
bootrec /fixMbr
bootrec /fixboot
Exit
Reboot your computer to check if the MBR has been repaired.
5. Conflicting Hardware or Driver
If your computer crashing just started recently, recall the latest installation. It might hold the key to solving the problem. It can be a new program, a new piece of hardware, or a driver update. There is a good chance that the most recent change is causing the problem. Check the Device Manager for any yellow exclamation marks and update drivers if available. You can also uninstall the faulty driver or program in Safe Mode if necessary.
How to Recover Lost Data Caused by Crashing Computers
The most ideal way to recover any lost data would be using the data backups you created beforehand. Your regular system image backups can prove more than helpful in the event of data loss. But not everyone has a copy of every file sitting around. What if we have no backups to fall back on? As long as the data loss is not caused by severe physical damage, we can mostly recover data with professional data recovery software.
H Data Recovery software, for example, is one of the best recovery software out there. It features 6 main data scan modules, each of which design to tackle different data loss situations such as deletion, formatting, crashed partitions, emptied recycle bin and USB flash drive problems. Restore your personal data after system reset, system crash or hard drive formatting, even without any backups is no longer a mission impossible! H Data Recovery Software implements unique algorithms to deep scan and reconstitute missing data and restore them to your local drives with efficiency and clarity.
