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.

I agree, the Optiplex GX270 is infamous for MoBos going bad. The capacitors have a manufacturing flaw, and up until February of 2008, Dell was replacing those boards for customers for free if it was found that the capacitors were the culprit. I just found a board yesterday with this problem. A sign that the capacitors are bad is either a buldge or they will be leaking an orange-rusted looking substance (primarily capacitors near the CPU). Symptoms of this problem include the PC rebooting itself randomly, and/or getting a BIOS error saying there was a thermal event.

As a temporary measure, taking the side panel off the dell 5150c stopped it from shutting down, so in my case it was clearly a heat problem, as suggested by previous the poster. The following instructions assume you're comfortable replacing computer hardware components - do at your own risk!
The solution is to buy an 'air duster' and some thermal compound for the CPU heat sink. If your CPU fan doesn't sound healthy (mine didn't), also buy a new one (ca. £20 on ebay: search for G9474 ).
Read the service manual: http://support.dell.com/support/edocs/systems/dim5150C/en/sm/index.htm for details on how to install / remove the fan and heat sink.
Clean out dust from the heat sink with air duster. Remove the fan, and clean or replace (recommended). Also clean the grill in front of the fan. Clean off old thermal compound from the CPU / heat sink and replace with a thin layer of fresh compound. Replace heat sink and side panel and you're done.

I have the same issue, in my case, in some Dell's I get a loud FAN noise as well, so far except for the FAN issue replacing the PSU had no effect so I think it is the MB/Proccessor. Recently dusting out the Processor worked on one of the mis-hap Dells which has thuis issue. I personally think Dell tech's should look into this and post some working base solutions!

Turn Off the computer, now as soon as you hit the power button, keep on holding "Alt" key & keep on tapping "F10 key,ie: Alt+F10, it will open the recovery console ,select full factory restore and follow on screen instruction. (Note:this will erase all datas on the computer) Hope this helps
