My compaq evo D510 was powering on and off intermittently when I tried to turn it on. I sometimes had to wait and unplug it and plug it back in. Then it finally quit powering up. I tried different memory and power supply. No help. The lights do come on the board. I can hit the switch and it lights up showing connection with the switch. Someone posted similar issue last year but no comment. But he called the power button a microswitch.He wasn’t sure if he should jump it. Can anybody help? cfuller777
