# Basic Computer Maintenance
There are variety reasons for a computer could be running slowly.
- disk fragmentation
- disk errors
- corrupt syste files
- unnecessary services running
- too many toolbars, BHOs, extensions, and/or add-ons/plug-ins
- clear browser cache
- not enough RAM
- dirty hard components

Please be aware these instructions are for Windows operating systems primarily. 

## Defrag System
With Windows 10, fragmentation is less of an issue than in previou versions of Windows. 

Never defrag a Solid State Drive (SSD). 
## Check for Disk Errors
Run `chkdsk` to check for disk errors, selecting the "Scan for and attempt to recovery of bad sectors". Bad sectors are often a sign that a hard disk is failing. 

## Corrupt Files

## Too Many Services Running
Software running in the background can eat up a lot of resources. Always check what's running if you're computer is running slowly. 

## Browser Clean Up
Toolbar, extensions and add-ons/plug-ins can all slowly down your brower. Check these things in the *Setting* menu of your browser to ensure only the add-ons you installed are running (sometimes third-party software and install add-ons without your knowledge). 

Remove unwanted programs in the *Add/Remove Programs* in Control Panel

## RAM
A quick way to speed up a computer is to add more Random Access Memory (RAM). RAM is fast, temporary storage for everything running on your computer. 

Without enough RAM, your computer will use your hard drive for temporary storage. Hard drives are much slower than RAM. 

4GB of RAM is the minimum. 8 GB is a good baseline; with 8 GB you won't notice your computer slowing down too much. 16 GB or 32 GB are for good if you have programs that requires a lot of processing. 

Most manufacturers make it easy to remove/install RAM. 

## Physically Clean Computer
Dirt and dust can restrict the airflow, preventing proper cooling which leads to overheating. Both desktops and laptops should be clean up from time to time. 
- Check all connections, make sure all fans are operational. 
- Unplug computer, open the case and clean out any debris, dirt, or dust you find. 
    - A clean make up or paint brush to get as much as possible.
    - Use a can of compressed air in areas the brushes can't reach, especially the fins of the CPU heat sink. *Do Not* aim compressed air at motherboard or electronic componets. 
    - Remove cards and RAM, clean contacts and reseat them.
    - Remove heat sink, remove all of old thermal paste, apply new thermal paste, and fit heat sink back into place.
