On average, companies will get anywhere from 2 to 5 years from an average desktop computer. This will of course vary greatly depending on the type of system you purchased and it's included hardware, as well as how your office needs have changed during that time.

The first signs of aging are generally sluggishness from the PC. Sometimes this can be easily remedied by adding memory, which has substantially come down in price over the past several years.

The reason this is often a viable option is that most PCs are shipped with memory that is sufficient for the time, but as you add software, virus scanning software gets more complex, and in general software uses more resources, the system will slow down. But depending greatly on the type of system and it's maximum upgrade potential, this may not even be an option.

Let us work with you to determine if your computers can simply be upgraded or if it's time to replace some of them.
