Dell Optiplex SX260 Computer Won't Boot Up

Hi,

I have a Dell Optiplex SX260 small desktop type computer that won't
boot up. When I press the power button, there is no display on monitor, no
HDD spin up noise. The only "life" I see/hear is the power light comes on and
the fans run. I tried a bootable CD, but the CD drive doesn't "run".

Note: I protected against static damage using a ground strap to my body.

I checked all the on board fuses (all good), solder joints, and power
supply output voltages with a load. The CMOS (RTC) battery is good.
I even removed and reinstalled the CPU.

Did anyone have the same problem with this model computer?

Thank You in advance, John

Inspect the capacitors.

Apparently there were some bad Nichicons, which would normally be
a good brand of capacitor. Most of the time, it's other (fly-by-night)
brands that fail prematurely. Nichicon is what you use when you need
a replacement.
