Dell is one of the most well-known computer brands currently on the market. Still, there are a few computer models that can experience motherboard failure and the Dell Optiplex GX270 is one of these models. Certain signs can identify motherboard issues for troubleshooting, but, in most cases, the easiest solution to motherboard failure is replacement.

Freezes and Sudden Restarts

Freezes and restarts for no apparent reason can be an indication of motherboard failure, but can also indicate other computer component failure. Check to see if the problem is power related by first pressing the power button, then watching the indicator lights and listening for computer sounds. If both lights and sound are normal, but no video is available, then the problem may be video related and not a motherboard issue.

Motherboard Failure

The Dell Optiplex GX270 is known to have defective capacitors. Open the computer side panel and look at the battery-shaped capacitors on the motherboard. If these are bulging or oozing a chemical liquid, then the motherboard has failed.

Power Supply Failure

Motherboard failure can often be confused with power supply failure. Touch the computer case and feel for an electric charge, if the computer can power on. A case that gives off small electrical charges indicates a failing power supply. Disconnect the power cord from the PC and check for a burnt, electrical odour from the back of the power supply where the fan is located. This is also indicative of a power supply failure, which can easily be replaced.
