The operating system of a computer is saved on the hard drive. If the hard drive is malfunctioning, then the operating system cannot be booted. This may cause an error message to appear on screen while the computer starts up. The message may say something along the lines of “Hard disk failure” or “Operating system not found.” In these cases, the hard drive must be replaced. Follow this guide on how to replace the Hard Drive.
Computers constantly monitor their internal temperature and will disable themselves if the temperature gets too high. The computer will even prevent itself from powering on if it’s too hot. Wait a few minutes for the system to cool down and turn the computer on again.
If the computer overheats often, then the cooling fan, heat sinks, and/or air vents need to be fixed or upgraded. Dust can collect inside a computer, clogging air vents and preventing the computer from cooling itself. A common fix is to open the computer and remove the dust using a compressed air canister. Dust removal should be done about once every 2 or 3 months to prevent an excessive buildup.
If the computer continues to overheat, then the cooling fan may not be strong enough to remove the excess heat and will need to be replaced or upgraded. Sometimes, the thermal paste between the processor and the heat sink can dry out and will need to be cleaned off and reapplied. The heat sink replacement guide includes instructions on thermal paste application.
The computer does not detect a USB device or does not deliver power to said device.
If the computer does not recognize the USB device, the USB driver may need to be updated. To update the software, follow this guide and select your current operating system. Scroll down until you find the current USB driver download.
First, make sure that the USB device that you are using is recognized on another device. If the device is recognized on other devices, then you’ll need to replace the USB port board. The board is located underneath the motherboard, so the motherboard must be removed to access the USB board.
The web camera embedded in the top of the screen doesn’t shoot videos or photos. Recorded pictures and video appear blurry or distorted.
If the built in camera isn’t functioning properly, then an outdated webcam driver could be the problem. Follow this guide to download the new webcam driver.
As the webcam is embedded into the front screen, replacing the camera means replacing the screen along with it.
Video playback is choppy and applications run slowly; The device boots up slowly.
The computer is searching for all relevant data within the hard drive, whether that is running a program or searching for files. If the data for a single file is distributed across multiple memory locations, then the computer will take longer to search for all the data. This is called fragmentation and can be fixed by running a defragmentation (defrag) utility. Defragging a drive groups all the data associated with a file in adjacent memory locations, so the computer can quickly locate all the data it needs for a specific program. First, close all running programs and applications. In the taskbar, search for the “Defragment and Optimize Drives” desktop application and run it. Select the drive labeled “(C:)”, click “Optimize”, and allow the app to run.
A full hard drive can slow down a computer because there’s less buffer room in memory to move data around. If you have less than 1GB of free storage left on your device, then you should make room in your hard drive by deleting unnecessary files and programs or replacing the drive with one of a larger capacity. Data from the old drive can be transferred to the new drive if needed.
Process are run within the memory space called RAM. If there isn’t enough space in RAM, then programs will run slow. Open the task manager and click on the “Performance” tab. Watch the “Memory” graph and check the memory usage. If the usage exceeds 75% under normal operating conditions, then the RAM needs to be upgraded.
