Well it look as if I have had this problem. I have 2 IBM 75GXP 30 GB drives, Visiontek GeForce2 GTS 32MB, samsung 256 pc133, 300Watt in-win case, floppy, sony cd-rom, nec zip 100,and running a thunderbird 1ghz not overclocked. I dont know what the problem is. I tried this three different cases, different AGP cards. Maybe I forgot to mention that I had the KT7-RAID running on my system before then I decided to upgrade to the KT7A-RAID. So I am still using the hard drives with the KT7-RAID data on them, does this make any sense? The only thing that worked is when I tried a PCI VGA card, it booted up to my WIN ME, then it found all the "new" hardware (north bridge, etc) again. I went back to the dealer and he said it was the power supply, so he gave me this case and a new motherboard. The board works fine (as far as I know) with the PCI VGA card, just with the GeForce, it doesnt display anything, everything powers up but no display. I tested the GeForce card on another computer, and it works, any suggestions would be appreciated.
