You explained that when he lost power and his computer shut down, all the data in RAM was lost.

Why does this happen?

  • RAM is static, so when you lose power, the data in RAM is not refreshed.
  • RAM is dynamic, and when you lose power, the data in RAM is not refreshed.
  • The data is not lost but is moved to the BIOS CMOS chips and then recovered when the computer is restored.
  • The data is not lost but is moved to the HDD.

While working on your computer, you receive the POST error, “Drive Not Recognized.” You check your SATA cable to see if it is the problem, and it tests fine. You remove the hard drive and test it in a computer system known to be in good working condition and find that the hard drive is working. You can move data and check to make sure the OS files are not corrupt. You use a power supply tester to see if the voltage for the SATA power connection is correct, and the test shows the power is correct. You even check BIOS to make sure the hard drive can be recognized and find that all settings in BIOS are at default, so the system should recognize the hard drive.

What might be the problem with your hard drive system?

  • UEFI has the wrong hard drive type.
  • Computer virus has deleted your MBR.
  • Motherboard SATA port has gone bad.
  • Hard drive jumpers.
