I got an A7V333 board today.
As soon as I opened the box, I checked out the jumpers and I tried testing it out of the case only using the CPU, Fan, power supply, video card and a stick of memory. No problem, system posted.
I then connected all my other devices (still on my desk) and tried booting again. Again, everything's great.
So I then mount it inside my case, screw it to the screw posts, hook everything back up, and start the system: No post, the speakers inform me "system failed cpu test".
I check all the connections again, same thing. I remove everything but the CPU, mem and video card, still "system failed cpu test". Additionally I sense a burnt smell coming from around the fan area.
So I'm thinking I fried it or the CPU. I test the cpu on another machine and no problems. So I unscrew the motherboard from the case in order to bring it back to the store.
I then decide to test it one more time, out of the case, and to my surprise the thing posted.
I then put it back in the case without screwing it in - still worked.
I then placed it exactly over the screw posts and used only two screws - not tightened (and I also screwed in the PCI/AGP cards) - "system failed cpu test", and the burnt smell came back.
I then removed all screws and displaced it slightly, and here I am writing to you.
What's happening here?
