There's one problem with this solution: The Acer Aspire One has no disk drive at all, so it doesn't matter if you have a copy of Windows on disk. I have one and have been trying to boot from the disk using a USB DVD drive (Memorex DVD+-RAM 530L v1) but it doesn't seem to want to let the disk boot, even after setting the drive to be first in the BIOS boot sequence; the boot sequence starts, then just goes right to that same error. How do I get it to boot from the DVD drive?

Consider Service if Under Warranty

You should be able to connect an external CD or DVD drive through the USB port and boot from the Windows disks that way. Before getting into those details, you might also consider Kat's original advice and think about taking your machine in for repair if it is still covered by warranty. Sometimes failure to follow boot sequence instructions are also indicative of a larger problem and, compounded with your installation error might mean your computer has a variety of issues. Rather than trying to stick your finger in the dam, a thorough inspection by an Acer technician will ensure that you receive the value of your investment and can enjoy your notebook in the long term.

Configure the BIOS Sequence to Boot from an External Optical Drive

That said, let's think about how to connect the external DVD drive and get the notebook to boot from it. There are two methods that you can try to get the computer to boot from the external optical drive but first you should remove it from the USB port and let things rest. You might even want to power your computer down to reset things. Put the Windows disk in the disk reader and reconnect it. Power your computer up. Now, you can either:

1. Press F2 as the computer is booting, as soon as you see the Acer logo on your screen
2. This should open the BIOS setup
3. Choose the Boot Menu
4. Follow the onscreen directions to set the bootable optical disk drive first

OR

1. Press F12 during boot up, as soon as you see the Acer logo
2. From the list that appears, choose USB ODD

Now, choose Exit Saving Changes or press F10 or press Enter to close the boot selection menu. You should now be able to follow the onscreen directions to reinstall your operating system or run the Windows Recovery disk.

Create a Bootable USB Recovery Flash Drive

If you have no luck with this, and your computer refuses to boot from the optical drive, you can create a bootable USB drive, but you will need a Windows Recovery disk and a second computer with an optical disk drive.

1. Put the Recovery disk in the secondary computer's disk drive
2. Connect a flash drive - with a minimum 1 GB capacity - into the secondary computer's USB port
3. Follow the directions detailed in the previous example to open the BIOS set up in the secondary computer and configure the ODD as the first device
4. Save the changes and exit the BIOS
5. Wait while the computer boots - you should see a list of options when it is finished
6. Choose install2usb
7. Now, from the list of disk presented, choose the USB drive and click Next
8. Now you have the Windows Recovery program saved on the flash drive - take it to the Aspire One and try again, this time setting the BIOS to the USB drive and try to repair your system this way

Consult with a Remote Assistant

If you have no luck with these steps, you might want to talk to a remote technical assistant who can troubleshoot with you in real time to help get to the root of the problem and determine an appropriate course of action.

When I turn on my computer, all I can get to is the BIOS and the screen is blank. Help?

Take your Hard Drive to a Technician

It's possible that your hard drive is fried. If your computer is still covered under warranty, you might want to consider taking it in to the dealer for repairs. To make sure that it is the hard drive that is failing, you can consult your computer user's manual to find the manufacturer, then visit their website and look for a diagnostic tool check the health of the hard disk. Most of the major hard drive manufacturers offer diagnostic utilities that could help you narrow down the possibilities though since the computer won't boot, this may not be an option.

Boot to Safe Mode

To get your computer up and running you can attempt to boot into Safe Mode. This way, hopefully, you can get access to your system with only minimal programs running, reducing the chances that you will run into problems. Turn your computer off, then turn it on again and start pressing F8. When you see the Advanced Menu screen, use the arrows on your keyboard to choose Safe Mode and confirm your operating system. The next time you boot your computer it will revert to Normal Mode, so there is no need to undo these steps.

Troubleshoot the Power Source and Cord

Another common cause of this kind of problem is a faulty power cord or battery. You can start by troubleshooting the power cord and outlet by plugging something else into the plug and swapping the power cord. You can also remove the battery and try the cord directly to remove the chances of a faulty battery interfering.

Reseat or Replace the CMOS Battery

Inside your computer there is another power source called the CMOS battery that is plugged directly into the motherboard. This battery allows the computer to keep time and other internal processes even when there is no other power source. CMOS batteries have an average life span of about 5 years, so it is also possible that you need to replace it. You can consult your computer's user's manual and check how to find and remove the CMOS battery. In some cases, removing the battery and then re-inserting it is enough to give it a new life, so you might want to try this before replacing it.

I hope these ideas are helpful, if you are still stuck, write again and let us know your computer model, operating system, and the results of what you have tried so far and we'll go from there.

When I turn on my computer this message comes up: MSI CMOS BATTERY LOW CMOS DATE/TIME NOT SET.PRESS f1 to run setup. Can you help?

Computer CMOS Batteries

The CMOS battery is your computer's internal memory and real time clock power source. This battery allows your computer to initialize its boot up procedure and remember the time and date, even when there is no other power source. CMOS batteries typically last between 2 and 10 years, but thankfully they aren't very difficult to replace. The CMOS battery is round and flat, about the size of a dime, but about twice as thick and will most likely say something like Lithium Battery and a code and voltage on it.

Try to Force the Computer to Recharge the CMOS Battery

The first thing that you can do is try to force the computer to charge the CMOS battery. You can do this by leaving the computer on for about 24 hours then reboot and see if you are still getting an error message.

Locating the CMOS Battery

If it doesn't work, then you are going to need to open the computer. If you have a PC, lay it on its side before opening. If you have a laptop, turn it over on a flat surface. Make sure that you unplug it from its power source and discharge any static electricity before touching anything inside your computer. Open the case and look for the battery on the motherboard. You might need to use your computer user's manual to help locate the battery.

Remove, Reseat or Replace the CMOS Battery

Sometimes unseating and reseating the CMOS battery is enough to get things working again, so you could try slipping it out then repositioning it. Otherwise, remove the battery and take it with you to the computer shop to buy a replacement. They are inexpensive, under $20. You should know that, in some cases, CMOS batteries are not removable. If it doesn't come out easily, or if there isn't a clip that you can lift to remove it, it is best not to force it. Either take the whole unit into a shop or consult your manual for more information.

Contact Technical Support

If you are going to open your computer and remove components from the motherboard, you might want to contact a remote technician for some real time advice. The tech can go through the steps with you to make sure you are comfortable. We recommend the services available here.

Could you please tell me how to repair error codes 1xx 161 164 2xx 3xx 4xx 5xx 6xx 17xx?

BIOS Error Codes

The codes you describe are BIOS error codes. Each one indicates a problem with a different component of your computer. For example, any BIOS error code from 100 to 199 is related to a system motherboard failure. Specific codes such as 161 within that range further identify the issue (with 161 representing a CMOS battery failure).

The BIOS is a small chip on your computer that contains its own small self-executing program. It is the first program that runs when your computer boots up. BIOS first runs a POST (Power On Self Test), testing all hardware components before loading the operating system. If one of the tests fails, an error code is generated and your computer may or may not continue loading.

Repairing BIOS Error Codes

Obviously, repairing an error code depends on which error code is displayed. For example, if you have error code 161, the CMOS battery failure code, then you would need to replace the CMOS battery. Because different BIOS makers have tweaked the POST codes to suit their own needs, it's best to refer to the BIOS manufacturer's list of BIOS error codes to ensure that you are working off a list that matches your computer.

When you receive a BIOS error code, this almost always indicates a problem with hardware rather than software. By deciphering the code, you will have a better idea of where the problem lies. For example, if you know that codes 200-299 indicate a problem with memory, then you know it's time to troubleshoot those memory chips. One of the chips may be bad or it may simply need to be reseated.

The codes that you listed, 1xx 161 164 2xx 3xx 4xx 5xx 6xx 17xx, are common error codes. Here's a brief rundown of each:

• 1xx (100-199) - System motherboard problem
• o 161 - CMOS battery failure
• o 164 - Memory system size error
• 2xx (200-299) - Memory problems
• 3xx (300-399) - Keyboard problems
• 4xx (400-499) - Monochrome video problem
• 5xx (500-599) - Color video problem
• 6xx (600-699) - Floppy disk problem
• 17xx (1700-1799) - Hard disk problem

In order to best troubleshoot the error code, let us know the exact code that you are receiving as well as the manufacturer of your BIOS. If you have Windows Vista, you can find out your BIOS details by going to Start and typing "System Information" into the search bar. Click the System Information icon and view the summary.

My computer is a Dell Dimension 9100 and the problem is that on switching the PC on it makes 6 long, drawn out beeping sounds but then after that nothing seems to happen. The screen is blank and the PC doesn't even seem to be on at all. Please help.

Beeping Bios

The beeping that you are hearing from your computer at start up is coming from the BIOS - the Basic Input/Output System - when it attempts to POST - Power On Self Test - to launch its basic functions and boot up. The beeps indicate that there is a problem, as I'm sure you've realized. One beep during POST is normal, as long as the boot continues.

Dell Beep Codes

The number of beeps signify different meanings for different makes of BIOS chips. There seems to be on ongoing debate among users about whether the 6 beeps you are getting indicate a DRAM problem or a CMOS reset, so we can briefly touch on both possibilities.

Reseat the CMOS Battery

The CMOS battery is the computer's internal power source that allows the computer to retain the time and other set functions even when it isn't getting any other power supply. CMOS batteries do run out of steam, so yours might need to be replaces, but more often than not, removing it and reseating it is enough to jump start your system. The battery you are looking for is round and thin, here's how to find it.

1. Turn your PC off, if it isn't already, and unplug it from the wall.
2. Lie the computer down and open the computer casing and take caution to discharge any static electricity before touching anything
3. Find the small round battery and gently remove it without forcing anything - if you have trouble locating it, use your computer's user guide for your model instructions
4. Now you can take the battery to the shop and purchase a new one of the same model number, or try to reseat the battery
5. Make sure the battery is firmly inserted, with the positive + side showing - or as instructed in the manual
6. Close the computer and try it again.

Check the Chips and Cards

The other possibility is the DRAM situation. In this case, there might be something wrong with the system board, or too much dust accumulated in the computer. To deal with it, open the computer and check the boards and the contacts. If there is a lot of dust, you can use canned air to gently clean it. Vacuums are not the way to go as the electric power can seriously mess with your system. Check the cards are all properly inserted and try to boot.

Try Tech Support

If nothing is working, you might want to try a remote technician. We recommend the services available here - a specialist will help you troubleshoot the issue step by step to help figure out a diagnosis, and a solution. Good luck!

How do I setup the BIOS up if I want to add an additional hard drive to my PC?

Make sure that you follow safety procedures when installing your second hard drive. Turn the power to the computer off and ground yourself by touching metal prior to installing the second hard drive.

Back up the BIOS

Before you begin, you might want to take the safety measure of backing up your existing BIOS and data files just in case something goes wrong.

Adding a Second Hard Drive

When you add a second hard drive to a computer, you need to set one of the drives as the master and the other as the slave. Typically, the primary hard drive or the one with the operating system is going to be set as the master drive.

Locate the cable that is being used for the primary hard drive. Find the connector that you can use for the second hard drive and use it. Secure the hard drive in securely using the screws and close the computer up. Make sure that it is properly connected so that you will have power going to it.

If the cable for the hard drive does not have a second connector, then you need to either replace it with one that does or use a second ribbon cable provided you have a place to connect it to the motherboard.

Adding a Second Hard Drive to the Setup

Follow these steps:

1)      Turn the power button on.

2)      Immediately after the memory check takes place, you need to enter the BIOS set up. You should see the information you need to do so on your computer screen.

3)      If it is available, the best step is to select the option for "autodetect." It might be labeled a bit differently. Press "Enter." If this option is not available, skip ahead to the step 5.

4)      Once the "autodetect" screen appears, you need to enter "Y." This will select the default settings for the drive that is already installed for use on the second hard drive. Now, skip to step 8.

5)      If you had to skip steps 3 and 4, then you need to manually enter the drive parameters for the second hard drive. Navigate to the setup screen for hard drives on the computer.

6)      Using your arrow keys, go through the list of hard drive parameters that is showing.

7)      Look for a set that does not go over the volume for your hard drive (e.g. 4 GB.) Select a set that resembles your hard drive and select "Enter."

8)      Press the option that accepts the settings that you have selected (OK, enter, etc.)

9)      Select "Save" and exit the setup. Press enter and the computer should restart if you have completed each step correctly.
