So i got my rig working etc etc and now the board i having a weird problem:

When i try to start the computer, and i press the power button, nothing happens. The mobo lights come on, the psu lights are on etc, but the power button or the power buttons on the mobo do nothing.....

NOW, if i bend the case by crunching (slightly) the rear towards the front- it starts right up when i press it? WTF! Right now I have my QPACK leaning on a pen so the chassis is slightly curved, and its working flawlessly, when i put the case back flat down.....it refuses to power on.

Im thinking grounding issue, any ideas?

PS- While installing my WCing i had a little leakypoo on the corner of the mobo adjacent to the DIMM slots and the ATX 24-pin, only 3 drops got on but the board had no power through it. I let it dry for 6hours and blew-dry it with a hair dryer for 30 mins...

Specs:
Black QPACK
venice 3000
bioster tforce pos
2x512 pdp xblk
6800(soon to be x1600xt)
OCZ modstream psu
a-c cooling....
 
try flipping the power bottom/led connections at the front of the case. The side with the label printed on it should be facing inward toward the case. If you look in the manual it will show you the right connections(black wire is negative, red wire is positive). I actually flipped it around the first time and it would power on but do weird stuff like trip the power button if I tilted the case slightly.
 
If you thought to bend it to fix the problem, it makes me think you think you did something to it that would be causing the problem. Does that makes sense? :D

Maybe you separated some circuitry that is now only connecting when you push it closer together?

Anyway, try some rubber washers, you're probably right that it's a grounding issue. No way your water cooling incident had anything to do with it.
 
You can test the mainboard connector with the other botton, (the reset botton connected on the power-on header)


It's means that is the mainboard header broken, or the push botton of the case ;)


See You :D

case button cant be the problem because the onboard PWR SW doesnt work either ;)

EDIT: wtf this is so weird. I did what the guy above me said and flipped the front panel connectors that were facing out to face inwards, and now the case works! But only when i dont touch it....Now the case will turn on normally when its sitting flat- but if you push on the front plastic panel it shuts off......
 
Put electrical tape behind the area where the button is, I've seen something like this with qpack. Buttons are sometimes a little fubar, and touch the metal behind them... resulting in odd effects ;p
 
Gonna try that soon, i know theres a little piece of metal somewhere causing all this nonsense.

EDIT: Problem seems to be back again, the case is now elevated ontop of one of the drive bay covers.
 
Polarity on power and rest buttons do not matter. Most likely your power button is shorting out to the front chasis, or your power button is FUBAR like mine was. temporarily swap your reset switch to your power button header on your mobo and use your reset switch as your power button to see if this temporarily (or permanently if you can't find a replacement switch) fixes your problem. I just transplanted another power switch from a spare case and mine works fine now.

I discovered this last night. Popped the front panel off to see what was causing the problem.

Turns out that the power switch has three bare leads sticking out the top, and when you push that area of the case in, they make contact with the metal panel behind the switch, thus giving the effect of pressing the power button.

I put a strip of electrical tape over the metal directly behind the leads and that stopped it.
 
The leads are not my problem.

Today i totally detached the faceplate from the case.....and just now it shut off randomely. Its not a soft shut down like what happens when you press the PWR button, its just a total turn off of the whole system- so it cant be the button.

Second off, even when this happens, the PWR buttons SOLDERED ONTO THE BOARD do NOT work. So this problem lies somewhere else...

Looks like all the bio/qpack combos in South florida are breaking these days huh
 
it turns out it is my new LiteOn DVDRW i got with the qpack..event viewer is showing an error and it only BSODs when im using the DVD rom
 
Its funny as I read this I see the newegg promotion for biostar motherboards. Lmao pen.
 
ive narrowed the problem down to the 24-pin connector the on the mobo....it seems that when i move it around just slightly the pc shuts off, i think theres a few pins in there or something that arent down tight enough...
