Hi, have just switched by long running Ultra-D for an Expert, and I've spent the whole day trying to get it to work. As you can see from my sig my psu is a Noisetaker, which doesn't have the 8pin connector that plugs into the motherboard, but I've followed the instructions of plugging the 4 pin into it. The board powers up fine, can get into bios fine, the problem comes when trying to install windows. I'm running the bios that was on the boardf when I got it, bios 12-07-2005 I'm trying to install XP pro over a Raid-0 setup of 80gig Seagates like I used to have, and at best I can get to setup the raid array using the floppy disc that came with my Ultra-D (didn't have one with my Expert, Unless I have lost it) and load the first 3 drivers off of the disc (same as last time - not sure why I need the raid 5 for XP one though.... [was told my a freind I need it]) I continue on the install procedure and the whole system hangs when reading from the disc, it stops at various different points, usually after loading all the files and begining instalation. Sometimes it even hangs before I have got to the raid drivers bit, hanging on "loading setup.exe" I have tried different sata ports, I have checked over all of my cables, all plugged in properly, and have even tried 2 other winXP discs.... Anyone got any ideas? I would be really gratefull. If any more information is needed just ask away I've posted exactly the same thing (under a different title) over on DFIStreet. So the rig is currently looping memtest.
