What can you do in a pinch to clear the CMOS settings if you are unable to find the CMOS-clear jumper?

After running Windows XP for a few years, Chris has decided to perform a clean install of Windows Vista. After backing up his important files, he places the Windows Vista DVD in the optical drive and reboots his machine—but it just boots into Windows XP like normal. What setting will he most likely need to configure in the BIOS to correct this situation?

Arnold has just installed a new sound card. He boots his system to install the drivers, but his system does not recognize the new card. What BIOS settings might he change using CMOS setup?

Alex has just finished making changes to the BIOS-level virus checking and would now like to save these changes. Name two ways to save BIOS settings after making changes in the CMOS setup program.

Ryan is working on an older Core 2 Duo system. What key or keys should he press to enter the CMOS setup program?

Jonathan is building a system using an Intel Core i3 processor, and he’s purchased a new moth- erboard from ASUS. He would like to use an old (but working!) ATX power supply he has laying around to power the system. Why might this not be a good idea?

John has a system that runs at 3.2 GHz and uses a 128-MB AGP video card. He uses Windows XP Professional and wants to try its multiple-monitor support feature. Can he add another AGP video card? Why or why not?

Dianne is trying to install an ATX motherboard in a new, empty ATX case. She tries to set it down in the bottom of the case, but it won’t fit—the ports on the side are too low to poke out the back of the case, and she can’t make the screws work at all. What has she forgotten?

After Erik reassembled his PC and turned it on, he noticed that the green LED and the disk active LED never light up, but everything seems to work okay. What is the problem?

You’ve installed an NIC and a PCI FireWire controller card on Susan’s Windows Vista Professional system. The system starts up fine, but when you check Device Manager, you see a yellow triangle with a black exclamation mark beside the NIC icon. What is the problem?

Your client calls you and says that her PC is unusually quiet and keeps rebooting for no apparent reason. What should you ask her to check?

Athena lives in an area where the power is often interrupted. She bought a good surge protector strip, but that does not seem to help. What does she need to prevent her system from shutting down unexpectedly?

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?

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 addi- tional 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?

Approximately how many watts would the power supply for this system need? • AMD Athlon 64 X2 CPU and 512 MB RAM • Two SATA hard drives and one floppy drive • One CD-RW drive and one DVD-ROM drive • PCIe video • PCI sound card • NIC

Explanation / Answer

1. We can clear the CMOS Settings by removing the CMOS Battery and replacing it, if CMOS jumper is not available.

2.Before Chris can boot from an optical drive, he should make sure that the optical drive is set as the primary boot device.

3. After Booting the System and Entering the BIOS Setup, Arnold should find the section that describes the sound card. For Ex: It could be under the "Advanced," "Devices" or "Peripherals" menu and labeled as "Onboard Audio," "Sound" etc.,

Select the Sound Option and Enable it. Save and Exit the BIOS Setup and reboot the system. The system shouls detect the drivers automatically.

4. F10 can be used to Save the BIOS Settings.

Exit by hitting the ESC key and will be prompted for saving the changes.

5. Ryan shoudl use the DEL key to enter the BIOS/ CMOS Setup for an older Core 2 Duo system.

6. ATX power cable has 20 pin or a 24 pin cable. If the latest Motherboard has 20 pin and the ATX is 24 pin, it may work fine. An adapter which converts a 24 pin power cable to 20 pin might work. If the motherboard draws more current, it may overheat the adapter and may cause a burn.

7. If John tries to change the memory addresses (these can be changed Device Manager> Resources), he might mess up with the system configuration. An AGP card could be helpful provided, the settings are managed.

8. Dianne must have forgotten the spacers(small rigid tubes made of rubber or fiber). These help in pushing up the ports to reach out the back case.

9. Did Erik connect the LED lights to the power? IF everything else is normal, this should be the only reason.

10. The NIC driver should be updated.

11. The power fluctuations should be checked.

12. A UPS should help Athena with her problem of her computer shutting down unexpectedly.
