Are you Sure that the computer model is Dell Optiplex GX260? Because looking at the manual diagnostic lights are found at the back. and the fault can be determine If the ABCD lights are yellow or green. But None the less 2/3 Depicts a hard drive problem while 3/4 depicts a memory issue.

Hard drive Issue:

1. Disconnect all non essential cables at the back of the computer. Leave only the mouse, monitor and keyboard. See if it boots up normally
2. If it boot up fine. try plugging one peripheral at a time until you find which peripheral causes the computer not to POST (Power on Self Test)
3. If you still getting problems, Follow these steps
4. To access the BIOS you must tap F2 or delete key upon turning the computer on
5. Try to look for the Hard drive if it is detected by BIOS if not got to step 9
6. Look for Boot Sequence or anything that is associated Boot
7. The Order boot of must be 1st: DVD Drive, 2nd: Hard drive, 3rd: Network etc.
8. Save the changes and Restart
9. If you still get the same message I suggest that you take out the hard drive and put it back in until it is detected in BIOS
10. If Step 9 did not work I think you need to replace the Hard drive

Memory Issue:

1. Open the chassis of the computer
2. Try taking out all memory modules
3. Rub the metal contacts of all memory with a pencil eraser
4. If more than one memory. Put one memory first and turn the computer on. If it turned on add another memory and turn the computer on. Repeat these steps until you determine which memory is faulty or all memory module contacts needs cleaning

I have a intel 478 board an don`t know how to connect power poer led


The power led wires ( there are two) go onto the two pins on the top row of the front panel coonetcor block on the board, on the 1st and 2nd pins working from left to right.

The full connector block is wired as follows:

top row: left to right >>
1st& 2nd are Power LED, the 3rd & 4th are the power switch, the 5th is empty.
The bottom row: left to right >>
1st & 2nd are hdd light, the 3rd & 4th are the reset switch, the 5th pin has no connector to the pin
Note: the power led and hdd terminals are to produce a light when the pc is on and busy.If the lights do not show, turn off the pc, turn the connectors round 180deg, reconnect and turn back on again. Job done

Powerbutton flashing yellow


If the main power button LED is flashing or solid yellow, this could indicate a hardware problem.

 

Was it running good before?

 

Are the diagnostic LED lights all green?

 

Here is what dell 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.

Do you remember what the BSOD said?

System not booting


if you are only getting a flashing line in the left corner of your monitor you may have a damaged cmos chip, because you should be able to atleast get into the bios, unless you have faulty memory, so if you have two sticks fitted remove one and try again, ensuring you use the correct memory slot.
