Hello,
recently tried turning on desktop pc an would do nothing. Checked my power supply and all voltages seem good, and did a continunity test on switch and its good. Don't know where to go from here.

what are you running
video card
cpu
m/board
ram
power supply
brand
wattage

check the listings in the bios for voltages and tempretures and post them

Sorry, maybe i was unclear, the computer will not power up at all, no lights on the front, fans do not start, nothing. have checked power supply and all volts are good?

the voltages may appear good but that does not mean it is not the power supply
where are the specs
where the 2 wires go from the case button to the 2 pins on the m/b
touch the 2 pins on the m/board for a fraction of a second with a small screwdriver and see if it boots the computer up
