Ok, I have the following:
Epox 8k3a+ and XP 1700
I had to mod my case to add a couple other hard drives to my case (they are going to be mounted on the floor of my case), which included drilling some holes into my case. Anyways, after putting everything back in the case, I tried booting up with all my original equipment and it didn't post. My mobo has some indicator leds and "led 3" was lit up red. Apparently, that led indicates that the board doesn't have power. I stripped everything down and removed evertyhing except my cpu, memory, and vid card. I tried booting and nothing happened this time when I pressed the power button except it looked like it was going to turn on since the fans had just started to spin, but then it just shut right back down.
I was frustrated so I ripped out another power supply from a different case and hooked up the ATX power connector and only the molex connectors for fans and tried again. However, I still had the same problem as before. The red led 3 was lit up and only my fans spun.
I tried clearing my CMOS and checked the atx power connection several different times, but I still have that same issue. Any idea?
I should also mention that this board has the idicator codes via a led panel on the board itself, but I don't receive any codes from that since apparently the board thinks it is not getting power.
