If you use an old computer with modern power-hungry applications then you may find your computer freezes randomly from time to time. Without any error to guide you to a possible cause it is better to fix computer performance problems like this using some broader approaches.

In this article, I detail the PC repairs I usually attempt when my computer keeps freezing.

Mechanical Checks

Heat: First check that none of vents on the PC are blocked. If you hear component damage (cooling fans sound odd, disk drive is making a scratching noise) then shut down the PC and seek expert advice to repair the mechanical damage. Our post on how to prevent computer overheating covers additional causes and information on ways to stop the risk of heat damage to your PC.

RAM: Open the Control Panel > System tool and check the full amount of RAM memory is being picked up by the machine. If not, then you will find computer freezes frequently happen as the PC strains to run on a lesser amount of RAM.

Software Checks

Disk Space: Check the disk space on each drive has over 10% left free. You can fix PC errors relating to performance easily by maintaining this minimum level for Windows to use as virtual memory. I once realized my computer is running very slow following a torrent download due to the hard disk going over 95% full so this is a problem that can easily occur.

Disk Defragmentation: Defragment the hard disks if you haven’t done so before. Tools like Regtool can improve disk access times and reduce RAM caching demands by the entire operating system just by defragmenting the hard drive.

Viruses: Run a full virus, adware, malware and spyware scan of all drives, including memory sticks. These can damage registry files and run as background services draining your CPU/RAM/Internet bandwidth capacity to the point where your computer keeps freezing. Fix computer viruses by isolating and removing the files. Make a note of the virus name/type to check if additional damage (e.g. to the registry) will also need repair before the PC freezes will be fully fixed.

Applications: Open the Task Manager on the processes tab and analyze which applications are using large amounts of the RAM memory. If the computer locks up when using one specific application then it should be easy to pinpoint if it using up all the RAM. If you don’t use/need the application then close it down. Check the applications own websites for any known performance issues or latest patch updates (some of which will include code changes that fix computer performance issues). Double check the application does not have any minimum system requirements which exceed your system.

Registry Corruption: If the computer freezes up randomly (i.e. not with a specific application) then I’ll also check the registry for faults. Some tools like XP Repair Pro and Error Fix have a free scan so it is possible to check if there are any severe registry key faults.

Hardware: When my computer keeps freezing after installing new hardware then I check the components website for the latest installation guide and executable for my operating system. Open the Device Manager and see if there are any device driver faults. If in doubt, I test the computer without the hardware installed to see if the laptop keeps freezing.
