Default Reboot while gaming/video, can trigger reboot by shaking case.

Hey guys,

I have a NZXT Tempest case with a custom loop watercooling system hooked up to an i7 920 (x58 motherboard). Video card is a GTX460.

Watercooling system is not leaking as it's been running for months with no change in level in the reservoir.

As I move every couple of months, my computer gets agitated alot. I'm not sure what this has done to my case but recently, my computer tends to reboot when I'm watching videos or playing games. There are no symptoms of anything going wrong up until the moment the computer crashes and restarts. No blue screen, nothing. Just like someone pulled the plug and put it back in.

I don't think it's a driver problem since the System Event logs always just say unexpected power loss or whatever it is when the computer decides to lose power.

I know that lifting the computer from the back with sudden force can also cause my computer to reboot. I don't like to do this, but I know that this triggers the reboot because I was once trying to move my computer to get access to a wire and it caused a reboot. No, it's not a loose power cable.

The last clue that I can give is that one time, when it shut off randomly, it wouldn't turn back on. Hitting the power button started the power for everything but no POST or Beeps and the 7 segment LEDs on the motherboard wouldn't even illuminate - as though a controller had died or a signal was being grounded somewhere. After waiting about 15 minutes and trying it again, it POSTed and booted with no problem. Had me super worried.

My friend suggested that something could be shorting due to a heat-related flexing problem. I've no idea where to start. I've taken everything out and reassembled it and I still get this problem. I've cut off molex connectors which were dying (you know those ones with the mangled pins that are getting loose because you botched connecting them? yeah) and taped up the ends. I really have no clue what's causing this. It doesn't matter that I have those paper discs between the screws fixing the motherboard to the case and the motherboard itself, does it?

Anyways, that's all I have for now. Help me out if you can! Thanks guys.
