My Computer is Running Very Slow – Possible Causes
Did your computer once run a lot faster than it currently does? This is a common complaint. When my computer is running very slow I like to go through a simple set of checks to identify the usual faults. These can pinpoint some of the most common issues you may experience.
- You need to update your applications. Perhaps your software is using old DLL files or other utilities. This can happen quite easily if your device drivers are also getting out of date and new applications have been installed. Get the latest versions of all your software and utilities, as well as running Windows update.
- You need more free space on the hard drive. Disk drive space has a huge bearing on the performance of your PC. You often find your computer running very slow if the amount of space drops below 5% as virtual memory will be constricted. Remove unused software and Tempe files from the drive to free up extra space.
- You might have a virus. Check your system for adware, malware or other types of viruses. Make sure to update your anti-virus application first.
- You may need to defragment your hard drive. Hard drive fragmentation causes files to be fragmented and dispersed around the disk. This makes it slower for your PC to access individual files. Over time this degrades performance drastically. Run This Defragmenter monthly to resolve the issue.
- You have too many applications running at once. When my computer is running very slow with specific applications open then this is the first thing I’ll try. Some programs tend to use too much CPU or RAM memory. Check Task Manager to see which programs are using the most RAM memory and close down background services you don’t require.
- Your registry file may be corrupted. The Windows registry contains system configuration information for all users and software. Over time it easy developed faults which cause errors and performance problems. Rollback changes using System Restore or run a registry repair tool to fix the faults.
