PC will not power up.

Tags: self built with ANTEC power supply, mother board ABIT-KN8 SLI

I have a self-built PC using an ABIT-KN8 SLI mother board. The PC became intermittent as to whether it would start or not and now it doesn't start at all. I follwed some advice from previous posts and found two things for sure: 1) if i jumer the green wire on the 24 pin connector to ground (Power supply to mother board connector), the system starts fine. I checked the power on switch that runs from the front panel to the mother board and it tests OK. I get continuty when I press the button. Release the button and continuity goes away, as it should. Next, I tried shorting the two pins that that power on switch connects to, still no power up. But, like I said, shorting the Power On pin (pin 14, green) to ground powers up the PC.

My question is, rather than pull the mother board to try and find the problem (and maybe create more problems), is it safe to just short pin 14 (green power on wire) to ground at the connector and leave it like that? A better solution, I think, may be to tie the power on switch to the Power on wire (pin 14) and ground. I may loose the functionality to be able to shut down the PC using the switch, but this PC stays on 24-7 except for an occassional reboot. I'm looking for an easy way out.
