I've got a Shuttle AK11 w/ a Duron 1Ghz and a Visiontek Geforce 2 GTS-V. When I hooked it all up and booted it for the first time, it worked, so I went into the BIOS and set the date and disabled the onboard sound, when I saved the BIOS it shutdown and tried to boot back up again, but all it did was give me a black screen. The thing wont POST at all, the fans and drives speed up and the CPU is producing heat, but I'm stuck with nothing. What the heck is wrong????
