Specs are as follows: Core 2 Quad Q6600 4 GB G.Skill RAM GeForce 8800 GTX 768 MB ASUS P5N32-E SLI 680i MoBo So, I get this puppy in, put it together, and power it on. Not 30 seconds to a minute in it shuts off, no warning. At first I thought it was bad connectivity so I checked, re-checked. Alas, no dice. then I began testing the RAM and so forth. No matter what combo of RAM I use, whether it be one stick, both, or none, I get the same result. So I test to see if it's the video card, sound card, everything I can think of. I even bought a second PSU, but still no dice. Also, during the connection of the second PSU, I forgot the CPU power plug, the 4/8 Pin guy. The PC retained power, but wouldn't shut off unless I did so via turning off the PSU. And, of course, it didn't boot at all. It powers on, lasts for a minute, shuts off. No chance for me to install any OS or anything. So. After I fool with it some more, switching things to different slots, etc. etc. I finally make it to the BIOS and see a brief error message. Something along the lines of "System interfered: Chassis opened ..... tempered with." Not sure what all it said because it immediately shut off. I've been dealing with this for 3 days, trying loads of things. Everything is seemingly fine. No signs of overheating or anything. Yet it still refuses to cooperate. My nerves are shot. I have a ton of school work to get done and was hoping this computer would help me in a lot of it (Photoshop/Maya projects, etc.) I need this guy working before Tuesday and Wednesday. Any clue on what my trouble may be? Any solutions?
