Computer freezes and lock ups are very common computer problem. No matter whether you have a netbook, and entry-level PC or a gaming system, random PC freezes can start occurring out of the blue. Sometimes the freezes and lock ups are only occasional, but sometimes they happen very frequently, like four or five times in an hour. Sometimes an error message is displayed, but most of the time the computer simply freezes and stops reacting for a couple of minutes. In some cases the freeze up can only be fixed by performing a hard reboot. Luckily, it’s possible to fix PC freezes and make your computer stable again.
The first thing you should do when your PC starts freezing and locking up on a random basis is to check running processes and applications. To do that, open the Task Manager by pressing Ctrl+Shift+Esc and go to the Processes tab. See if there are any processes that are using excessive amounts of CPU and RAM. If there are, identify the applications or services running them and act accordingly. For example, if you have uTorrent consuming 100% of CPU, right-click on the corresponding process and kill it. Then update your uTorrent client. However, if it’s svchost.exe using 100% CPU, you need to first identify what’s running the svchost.exe process and only then you might be able to kill it.
The second thing you need to do is check whether you are getting any error messages when your computer freezes up. For example, you may be getting a video card driver error. If that’s the case, go to your video card manufacturer’s website and download the latest version of the driver. You might need to fully replace the existing driver to fix the problem. It also wouldn’t hurt to update your operating system.
If the PC freeze occurs when you are using a particular applications, especially if it’s a resource-hungry program like Adobe Photoshop, check that you have enough RAM installed. Chances are that your computer doesn’t have enough resources and you simply need to add more RAM. If you have enough RAM, try updating the application because this might be a known issue and the software developer has released a patch to fix the problem.
Another thing that can be causing the freezes and lock ups is lack of free disk space. Check your hard drive by right-clicking on it and going to Properties. If you have less than 15% of free space left, move some large files to another volume. This will help you fix the freezes.
And finally remember to run a good quality registry cleaner to identify and repair corrupted registry entries. Registry errors are often responsible for PC freezes and crashes and a good registry cleaner can help you fix the problem.
