Question about Dell OptiPlex SX270 PC Desktop
My Dell Optiplex SX270 fails to start when I press the power button. I made sure all cables were secure, which they were. I then saw that the light on the adapter was green so I knew it was getting power, I then saw that on the inside of the computer an orangish, yellowish light was on, so I knew the CPU unit was recieving power, but the unit still failed to start. Please help me
I'm reasonably sure that it is a bulging or bad capacitor issue. We have had Dell replace a large number of motherboards on SX270 and GX270 computers, due to underpowered or counterfeit capacitors on a large batch purchased back in 2005. The capacitors swell or burst until the computer will not turn on anymore. You'll get the amber light inside the unit, plus a green light on the power supply, but the computer will not power up. You can try the solder technique, but you'd be better off replacing the system board, if possible. Happy trails!

I have seen the same probelm on other dell computers. They have a problem with ther capasitors that dryes out. If you open the computer, it is possible to identify the bad capasitors, the have a round top (normally flat). It is normally 6 to 8 capasitors, that are faulty.
A repairkit can be bought and if you have experience in soldering, then the computer should work after replacing the capasitors. I did it with success
The problem is that the capasitors used aren't specified to be used in this temperature range and thats why they stop working after a while

Does it display anything on your monitor?
(if yes then please continue)
Do you see BIOS load when you start your computer?
(if Yes then answer the next question please)
When booting up do you receive any kind of error message (ie. Hardware Failure, Could not load Operating System).
