Ok guys, here's the full story...and I'm afraid there aren't many solutions left...
I was getting bad temps with my new watercooling setup. So I go to reapply AS5 (I applied a little too much the first time through) and when I seated the CPU back on, it held. However when I went to power up, the system speaker went *beeeeeeeeep.........beeeeeeeeeeeep...........beeeeeeeeeep* long beep, long pause, long beep, although the two CD drives started up (the lights blinked on them both). So I figured I had seated the CPU wrong, although it fitted, so I went to reseat the cpu.
Dangderden has something with their waterblocks. There's no way you can take them off the cpu after you've put them on. The AS5 holds like glue and you practically have to pry the CPU off. Anyway when I pulled on the heatsink, the cpu came out of the socket with it. No big deal, I figure, and I slowly twisted the CPU off. But I damn nead had a heart attack when I saw that 8 of the pins were bent, 4 on one side and 4 on another.
I took a small flathead screwdriver and bent them back (this is the scariest part, what if I overbend them and they snap off??) and when they all looked straight I reseated the CPU with great care and concentration, and this time I made sure it was down (and it was, and it held, and the arrow pointed the same way as the motherboard). I put the heatsink back on, everything looked fine, took the comp back into my room and plugged everything in. I hit the switch on the PSU, and everything booted up (the thing with the Neo2 is that you need to hit the switch, which turns on the fans and stuff, then hit the power button to POST the motherboard). I hit the power button. Once. Twice. Five times. Nothing. The CD drives didn't even blink on.
So I do the first thing that comes to my mind: check the power cables. I unplugged and plugged each one back in, and still nothing. I reset the CMOS, same thing still happens.
Here's the situation I'm in now. I hit the switch for the PSU, the fans on the radiator, northbridge, and video card all turn on. The water pump turns on. Everything is running like it should on the Neo2. I hit the power button to initiate the bootup, and nothing happens. It doesn't even beep or blink or anything. You may think the power button is bad or something, HOWEVER: when I hold the power button down, the comp turns off. When it's off (and the PSU is on) and I hit the power button, the comp turns on, but doesn't beep or blink and no screen. Any new ideas? I'm afraid maybe I broke the CPU?
EDIT: Oh about the motherboard...I first received it back in November, but it was slightly screwy so I RMA's and got a new one in January-February ish. I don't wanna RMA again...taking the system apart right after I set it up is a nightmare, especially with water tubes going every direction.
And one more thing I forgot to mention. Remember when I was hearing the long beeps? Before I reseated my CPU I thought it was the ram, so I removed a stick. When I heard that it gave me the same beeps, I plugged it back in and went ahead to reseat the CPU. I don't think it's the ram though but it might be.
