If the hard drive seems to be running slow, check the following:

• Check to see if you have a slow device on the cable.
• For IDE drives, in BIOS setup, check to see if it is set to Ultra DMA or PIO mode. Ultra DMA is faster, as long as the drive supports it.
• Use a voltmeter to verify that each output from the power supply is correct. If any output is very low (especially the +5 volt output), replace the power supply.
• Check other environment factors such as smoke, heavy dust, high humidity and anything that may generate a strong electromagnetic field such as heavy machinery and motors.
