3. Your assistant technician calls you and says he suspects a bad power supply in one of your client’s systems. He said the multimeter readings are 12.65 volts and 4.15 volts. What should he do?

4. One of your clients has an older Pentium 4 system with a single IDE hard drive and 512 MB of RAM.

He had been using this PC as his main workstation, but he’s recently purchased a newer system and now wants to redeploy the older system as a file server on his network. He has ordered a PCI SCSI controller board and three SCSI hard drives, so that he can configure a RAID array, and an additional 2 GB of RAM. He also ordered two Y adapters for the power supply connectors. He asks for your advice about any additional hardware he should order. What do you tell him?
