Hi

Power up the Optiplex GX260 and check the QUAD Pack Diagnostics LEDs (located at the back). Compare the LED pattern to http://support.dell.com/support/edocs/systems/opgx260/en/ug/solvprob.htm#1167139 for more info.

Ideally, to troubleshoot and resolve the issues, try removing all PCI devices, disconnect all external devices/peripherals including keyboard and mouse. You may leave the Monitor connected. Power up the PC and check for successful Power On Self Test (POST). If POST completes (generally fails on "Keyboard not present"), shutdown, connect keyboard and try POST again.

If all goes well, install PCI devices one at a time and test successful POST. This will help identity a failing device.
If issue persists, after removing all devices, remove the CMOS battery for about 90 seconds and try POST again. If same, remove all DIMMs (Memory) and check for beep codes. Compare beep pattern to http://support.dell.com/support/edocs/systems/opgx260/en/ug/solvprob.htm#1176760.
NB: Ensure to remove power lead and press power button briefly to use up flea power before working in the system.

If the system beeps, it suggests that the CPU and systemboard are "likely" fine. Install one DIMM at a time and test successful POST. If there no beeps then the systemboard and/or CU is/are at fault.

Start with a boot disk. run a scandisk to find any errors, then try using fdisk to reconfigure your partitions, enabling you to format. this has worked for me in the past with desktop pcs.

this sounds like a bad power supply unit. First check that your Ram and graphics card a free from dust and dirt by removing them from their slots and cleaning them with a dry soft paintbrush then replacing them gently but firmly. Next check that all of the power cables going into the motherboard are pushed in gently but firmly. If this is done and you still get the same problem, then I suggest changing the power supply unit.

There are 2 probable causes for this. What is the power rating on your power supply? Less than 400W is going to have a hard time running newer boards and a SATA drive.

Also, how many cooling fans do you have? hopefully you have at least 1 case fan and 1 cpu cooler fan. If you don't have adequate cooling then your system will shut itself down when the cpu gets too hot. I've seen this a lot when someone builds a system with no case fan, and it usually gets about 30-50% into loading windows before the system powers itself down.

If your dell machine is recognizing the keyboard properly and installing its own built in drivers properly then the USB ports are working and it a problem with your keyboard
