Create a suitable environment

• Keep your computer cool: Computers are sensitive to heat. Generally it is a good idea to run computers at normal room temperatures. Computer components will start to fail at excessive heat (over 25C/85F), or if too cold (below 10C/50F). Note these temperatures are guidelines only - different components have their individual specifications. Most serious computer installations have air conditioning as a standard component as it is better to run systems in slightly cooler conditions rather than warmer. Note that running computer components generate heat themselves!
  
  
• If you bring your computer in from the outdoors, wait until it gets to room temperature before using it.
  
  
• Avoid exposure to direct sunlight: This can dramatically increase heat build-up.
  
  
• Ensure proper humidification during dry seasons: Electrical discharges in low-humidity conditions will often destroy computer components and/or erase disk information.
  
  
• Ensure quality electricity: Protect yourself from electrical irregularities. As a minimum, put a quality surge-supressor between your computer and the power outlet to protect against spikes. Although this will not protect against brownouts (when the voltage drops -the times when you see the lights dim momentarily), which are the worst for your computer.
  An UPS (Uninterruptable Power Supply) can be used to provide good power during brownouts or surges, as it will switch over to a battery backup during power irregularities, spikes or dips. These are relatively inexpensive these days, and good insurance for the health of your computer equipment.
