what problem.
all you said is MAfee disk is bad

Dell OptiPlex... | Answered on Jan 13, 2015


If I follow you correctly, you are asking what setting you should have in the BIOS to make it Boot again.
Fastest solution is to return to the BIOS and use the option of "Load Setup Defaults". These are the settings that the Manufacture or the OEM Motherboard Manufacture would have used during setup.
With any luck, that should allow the system to restore to booting status.

I hope this helps.

OPERATING SYSTEM. That would be Windows.

You are in BIOS Setup, and shouldn't be in there.

Computer OFF. (Press the Power On button, and hold it for 10 seconds until the computer turns off; if it is on)

Press the Power On button, and hold it in. Hold for a count of 10 seconds. let go. Do this same procedure 2 more times.

If the Power On LED light blinks, when you press the Power On button for the third time; hold for ten seconds, let go; do it again.
Keep pressing until the Power On LED light doesn't blink on.

This resets CMOS Error Codes, and resets BIOS Setup back to the factory default settings.

Operating system error is solved by installing the Restoration Disk/s, and when asked choose Repair. (Non-Destructive Installation)
If this doesn't solve the problem, you have a bad harddrive data cable, or a bad harddrive.

my dell GX 620 pc show orange light and refuse to boot up

Dell OptiPlex... | Answered on May 27, 2012

For the Dell Optiplex GX150 Desktop PC?


Motherboard chipset: Intel 815E

Northbridge chip: Intel 82815
Southbridge chip: Intel 82801BA


Under the subheading - Chipset - scroll down with your eyes to -

Look to the right.
You will see - 82815 - under - Part Numbers.
That is the Northbridge.

To the right of that, you will see - ICH2 - under Southbridge.

Scroll the page down, until you come to the BOLD heading -
Southbridge 8XX chipsets.

You will see ICH2 is Intel part number - 82801BA

The I/O controller hub is in the Southbridge chip.
I do not know what the Super I/O chipset is.

[ The Northbridge chip should be under a finned Heatsink. If so, you will not be able to see the Intel part number.

Looking at the motherboard as a map, with the Processor to the Top, and Ram Memory slots to the Right, the Processor is NORTH.

(Ram Memory slots are to the EAST)

Coming down the motherboard, the Northbridge chip is under the Processor.

Come down further, and slightly to the right, and you will see the Southbridge chip.
It has Intel 82801BA on it, with other Intel information ]

HOWEVER, here is a list of Super I/O chipsets,


[ It comes up to the Wayback Machine. Wait a couple of seconds, and the Super I/O chipset page will come up ]

If this is a general question about the Northbridge chip, Southbridge chip, and Super I/O chipset;

Motherboard diagram,


CPU stands for Central Processing Unit. Another term used is Microprocessor, or simply Processor for short.

The Processor communicates with the Northbridge chip, through the Front Side Bus. (FSB)

The Northbridge chip communicates with the Southbridge chip, through the Internal Bus.

The Southbridge chip communicates with the Super I/O chipset through the LPC Bus. (Low Pin Count Bus)

The Northbridge chip handles the faster capabilities of a computer.
It handles the Processor, Ram Memory, and HIGH-speed graphics.

AGP (Accelerated Graphics Port), and PCI-Express, are HIGH-speed graphics.

A graphics card inserted into a PCI slot, or Integrated Graphics, is
NOT high-speed graphics. This is handled by the Southbridge chip.

The Southbridge chip handles the slower capabilities of a computer.

and Audio. (Sound)

This is more information on the Northbridge chip,


For more information on the Southbridge chip, simply left-click on the blue - southbridge, in the end of the first sentence.
(....the other being the southbridge)

You can also search the following in Wikipedia, by typing them in the search box to the upper right, and clicking on the magnifying glass icon.

Northbridge (computing)
Southbridge (computing)
Front-side bus
Internal bus
LPC bus
Super I/O chip, and so on.

Hi, just pull out your memory card and clean it with an eraser. And insert it tightly again and don't forget to clean also the memory bank.

Hope it will help you.

just install motherboard disc for sound and see whether your connecting wires are correctly working or not

Dell OptiPlex... | Answered on Mar 27, 2012

Im not sure that you understood the concept of resetting the hdd...this can be done only by formatting ...and from the windows you can not format but the partitions(drives) that not contain the windows installation ...to be able to format all partitions you have to use a installation cd with the operation system ( a boot-able one ) ..and boot from cd ...by selecting this operation from Bios settings ...and go along with the clean installation not from the recovery partition or cd ...
after you get along with the clean installation and formatted the hdd and remake the partitions ...and finished the installation of the operating system ...than you can use the recovery cd to install the drivers and the factory settings and programs .....
another easy way to do that ..is to hook it on another computer ...and just format it from windows...this will erase it clean ..and you will have to reinstall the OS after that ...

Motherboard failure, most likely, possible expansion card issue

Dell OptiPlex... | Answered on May 20, 2011

It sounds like a power failure.
If it is plugged into a surge protector, try resetting it. In the Dell manual, it says, "if the power light is blinking amber - The computer is receiving electrical power, but an internal power problem might exist. Ensure that the voltage selection switch is set to match the AC power at your location (if applicable).Ensure that the processor power cable is securely connected to the system board (see page 73)."
There is another thread on FixYa that might be of some use: http://www.fixya.com/support/t274632-dell_gx150_power_light_flashing_orange.
Finally, I checked a Dell forum and found this discussion: http://en.community.dell.com/support-forums/desktop/f/3514/t/17794576.aspx.
If you do need to replace the power unit, I found a replacement part athttp://www.discountelectronics.com/index.php?l=product_detail&p=2168.
If you are not comfortable replacing the part yourself, you can use a PC repair service, such as the Geek Squad. It might be worth getting a second opinion.
Thank you for using FixYa!

Once installedreturn to "drivers and downloads" and enter the "servicetag",(serial number) of the computer. Dell keeps a listing of driversfor every customer's computer they sell.

While some desktops come with quad-core processors, unfortunately the Dell OptiPlex GX150is not one of them.

Dell OptiPlex... | Answered on Feb 28, 2011

Did you set the jumper(s) on the new drive to match the settings on the old drive (usually CS or Cable Select)?

Did you double check the power connector was snug on the new drive? You may also want to double check the connector on the motherboard, SF systems are cranky about moving around, and mave have unseated the motherboard end of the cable.

There are a few possible sollutions, either your motherboard is faulty the processor, or the processor/motherboard settings.Here are some steps to follow to acertane which problem you have.

  1. Unplug the computer from the mains and take the side panel off remove any cables connected to the motherboard,exept the power cables, blow away any dust built up on the board and reboot the mechine.
  2. Turn the computer off and remove the little round lithium battery found on the motherboard for about 30 seconds and then replace, any settings that have been changed in the bios will return to factory defaults.
  3. If still the same problem persists and if you are confident enough to take the fan off the processor do so, there should be clips either side of the fan to take it off and expose the processor, with a dry cloth rub away any white coolent from the underneath of the fan and the top of the processor. you can by cooling compound from any pc store, reapply the new compound and reapply the fan to the processor and clip it back down. Reboot mechine Still nothing you could take it to your local pc store and ask them if they have a tested working processor that you could try.
  4. If all else fails you could have a faulty motherboard, find out what processor you have and memory the system uses and purchase a new mother board you could try here: www.ebuyer.com.

restore your computer using the restore partition or restore cds, you can try to do a repair install of windows but sometimes that can hurt rather than help. if you want to f ind out the reason why hit f8 at boot and scroll down to 'do not restart computer after system failure' and hit enter, when it fails again it will give you a stop code looking similar to 0x00000000 that will give us a little better idea of what the issue is.
