Im trying to install a fresh new Windows XP SP1 on this PC. I just bought a Seagate 7200.10 SATAII and enabled it running at 3Gb/s. While installing windows XP, at the part Installing Devices, at about 3/4 of the green bar it will stuck there for quite a long time, at the bottom right which those green boxes which suppose to be moving, it will sometimes freeze for 30 secs+ and will be moving again. But now my mouse won't work, it's normal USB mouse, the optical LED doesn't light up, and most importantly my CD rom doesn't eject anymore. I don't know what's going on. I removed all other drives except this seagate 7200.10 HDD and a benq 1920 PRO dvdwriter. I've tried SP2 too it doesn't work. I don't know whats going on. anyone can help me?
