I have had that happen on Optiplex units. It is a sign that the motherboard is going or has gone bad. Cure is to replace the motherboard.

A few potential problems:

1. Your CPU fan isn't working, causing your CPU to overheat and then turn off the system
2. Your power supply is faulty
3. A capacitor has blown on your motherboard

Give us more details on your problem so we can figure out what's going on

Can't turn my computer on and i have a yellow blinking light on my dell dimension E510


Do you use a surge protector? If you do, try turning off the power supply to the surge protector and switch on again.
There are a number of causes for this problem, the most likely being a PSU problem or a motherboard fault/failure. To check the power from the PSU to the motherboard, you will need a multimeter to make sure enough power is going to the motherboard. Also check the motherboard closely to see if there is any signs of corrosion or blackened areas, which could be caused by overheating components. Check for leaky or burnt capacitors.

Computer fan running constantly


Computer fan will always run and act as a ventilator to send the heat outside the CPU.
So, don't worry, be cool.
Thank you.

Computer won't turn on


A flashing yellow power LED is an indication of a failure in the power supply. If under warranty, Dell should be replacing it. If out of warranty, then a 400/450 Watt ATX power supply should resolve the issue.

Unplug the power cable from the power supply in your computer and reinsert it. If you still have nothing, most likely a dead power supply.
