Ed, Check that you connected your floppy and hdd properly (as you probably did many times by now). I had a similar problem and I had connected the floppy incorrectly. Are you sure your powersupply has the correct voltage supplies? Is your mobo being grounded anywhere (touching anything like case metal)? _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com The NOSPIN Group provides a monthly newsletter with great tips, information and ideas: NOSPIN-L, The NOSPIN Magazine Visit our web site to signup: http://freepctech.com
