So my 1ghz pc died last week and instead of buying a complete one, I bought all the parts and put it together myself, oops. Everything is done correctly according to the instructions, the jumpers in the right place BIOS is set up right, the problem comes when I try to install windows xp. I have 2 different XP discs each with keys, they are not new so I don't know if that causes the problem, no scratches or fingerprints. when the pc goes to load the disc it just says "invalid startup disc, insert another and press any key." It is a AMD Anthalon 3200+ cpu on an Abit AN7X.....correct motherboard. The HD is a Seagate SATA. I have the DVD hooked up to IDE #2 as the primary and the HD on SATA #1 The odd thing is, the first time I went to install windows, after setting up the BIOS, it loaded the XP disc, then said there was no HD to install to, I looked and saw that the SATA cable came undone. When I hooked it back up and tried again, that's when I started getting the "no-load" I have tried two different DVD drives, gone from IDE #2 to IDE #1, no difference, the bios is set up to boot from the CD before the HD???? Any ideas?
