So this problem I'm having is really bizarre. First off, here's my system components:
EVGA X58 3x SLI motherboard
Intel Core i7 920 CPU
12GB G-Skill RAM
2 1.5TB WD Green Hard drives (RAID 1 using onboard Intel controller)
Antec Signature Series 850W PSU
Dual EVGA 9800 GT 1GB Graphics cards
Ok... that said, here's my problem. If I lay my computer down on its side, it works just fine. However, if I put it back upright, within 1 minute, it will do a hard shut down, almost as if I had held the power button down. Works every time. If I start the computer up in the upright position, sometimes it will shutdown before it even gets through the RAM check, other times it will hard shutdown after booking to Windows 7 - seems pretty random as far as the timing goes, but as soon as I lay it back down again, it works fine (I'm currently typing this with my computer in laying-on-its-side position).
Here's what I've done to troubleshoot it it - I tried pulling out the connectors to the case's power/reset switches to see if there was a problem with them, but that didn't change anything. I tried pulling out each graphics card and rebooting - still get the same problem. I ultimately pulled the whole thing apart to see if there was a loose screw or something floating around, but found nothing. I'm at a complete loss. Has anyone seen anything like this before? Any ideas or suggestions would be super helpful.
