GX150 optiflex "setup utility" configuration


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.

Power button not turning computer on


this is most likely a short in a computer component, You need to unplug everything from the computer incl CPU, Memory, Add on Cards, Hdds, the lot, just have motherboard plugged in and push power, if it powers up (there won't be a pic but you will know it's working) start replacing parts one by one until it won't start and that is the faulty part. If it does nothing with just motherboard plugged in the motherboard is at fault and needs to be replaced, If you have had the motherboard out make sure no of the metal mounts in the case are shorting out anywhere under the motherboard as this will also cause the same fault.

Proper installation of tower wires


According to Gateway Support, the Gateway 505GR desktop computer uses an Intel (Ausberg) 915G motherboard,

http://support.gateway.com/s/PC/R/3724/3724iv.shtml

Intel (Ausberg) 915G motherboard,

http://www.ascendtech.us/itemdesc.asp?ic=MB4GWAUGSBURG

Scroll down to the photo with the sections marked in red.

In the top link, looking at the motherboard with the computer case open, the USB and Firewire (1394a) cables, can be seen attached to the motherboard near the letters D, E, and F.

In F that red cable is a SATA cable. One end attaches to the back of the SATA harddrive, (The angled end), and the other end of the SATA cable attaches to one of those SATA headers on the motherboard.
(SATA header = SATA connector on motherboard)

Preferred SATA header for the Harddrive is SATA 1.
DOESN'T matter though. That's the beauty of SATA. You can plug the SATA data cable into ANY SATA header on the motherboard, and BIOS will find the harddrive.


In the second link, looking at the motherboard photo shown, and comparing it to the view of the motherboard as mounted in the computer case, the Front Panel header is at the very Bottom Right.

Two rows of pins in a White rectangular shaped header,

http://www.ascendtech.us/itemdesc.asp?ic=MB4GWAUGSBURG

(S points to Front Panel header)

[ The plastic front of a desktop computer is the Front Panel.
The area of pins on the motherboard, that the Front Panel wires go to, is the Front Panel header ]

A) Top row has Even numbered pins
B) Bottom row has Odd numbered pins.

http://www.intel.com/support/motherboards/desktop/sb/CS-009016.htm

1) Power LED = Power On LED light
2) Hard Drive Activity LED = LED light that flashes (Usually red in color) when your harddrive is active. Being used.
3) Reset switch = Reset Button. The Reset switch is behind the Reset button. (IF the computer uses a Reset switch)
4) Power Switch = Power On switch
5) Forget about Pin 9. That's for 5 Volts DC - Out. Used by factory.

Which wires coming out of the Front Panel, are the Power On wires, Harddrive LED light wires, Power On switch wires, etc.?

Remove the Front Panel, and trace where the wires end.

IF, the wires already installed coming from the motherboard to the Front Panel, are Too short, you should make notes before you remove them from the motherboard.

Note what color pair of twisted wires, went to where, in the Front Panel.
Compare to the chart of the Front Panel header given above.
(IF any wires are still connected to the Front Panel header on the motherboard)

Once the Front Panel is removed, it's usually pretty easy to trace the two wires up to the Power On switch.
Same for the Power On LED light.
Again, same for the HarDDrive activity LED light.

The SATA harddrive requires a DATA cable, and a SATA power cable.

The connector for a Data cable has 7 contact pins. It is the shorter connector.

http://en.wikipedia.org/wiki/File:SATA_Data_Cable.jpg

The connector can be at a 90 degree angle as shown, or a straight connector.
IF the data cable has an angled connector, it plugs into the Harddrive.
Straight connector goes to the motherboard.

The connector for a SATA power cable has 15 contact pins. It is the longer connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

Note the L shape of the connectors for the SATA data cable, and SATA power cable.

Also;
This is a 4-pin standard Peripheral power cable. Commonly misnomered as a 'Molex' power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

IF, the SATA harddrive has a provision for a SATA power cable, AND a 4-pin standard Peripheral power cable, ONLY use just the SATA power cable.

Using both power cables will burn up the harddrive.
May not happen immediately in some cases, but WILL eventually happen.

My dell gx260 ligth come green if i turn it on but for a few mins time it turn orange why


Do you mean the monitor's power light starts green and then turns orange when you turn it on? Most monitors will go to a power saving mode when they do not get a signal from the computer.

The Dell GX260 has a green power light when on. When the computer is off, the light is off. If it is green and blinking, then the computer is in a power saving mode.

Diagnosis: start with the obvious: is the monitor cable plugged into both the computer and the monitor (if not permanently connected to the monitor)? Are you connected to the active port? (You can add a video graphics card in most desktops. The motherboard video port usually needs to be disabled to use the card ports. If you plug in the monitor cable to the disabled port, it won't work.) Is the monitor set to the correct input? (This applies if the monitor has several ports. In that case, there will be a Source or Input button on the monitor.) Is the computer on? The GX260 has the power button on the front. (Other computers have the power button on the top.) There is also the power supply switch on the back which needs to be on.

Next try a different data cable between the monitor and the computer (if you can). Try a different monitor. If a second monitor works, than the monitor has a damaged main board. If the second monitor doesn't work, then the video graphics adapter has probably failed. Replace the add-on card, if in use, then boot in the safe mode to remove the old graphics driver. Then install the correct driver for the graphics adapter.

Note: the computer and the monitor should both be off when you connect the cables. Then turn on the monitor first and set it to the correct source before turning on the computer.)

I hope this helps.
