I purchased a desktop computer from Dell, Dimension 9150. It has 500GB Serial ATA II Hard Drive (7200RPM) w/DataBurst Cache™, 256MB PCI Express™ nVidia GeForce 6800, 1GB Dual Channel DDR2 SDRAM at 533MHz- 2DIMMs, Pentium® D Processor 940 with Dual Core Technology (3.20GHz, 800FSB). I purchased xp home version with it, now I want to format the hard drive, create new partitions and install XP Professional. After I boot the computer with the installation CD, before if starts installation, I see xp's famous blue screen. I tried again with some other CDs, but I saw the same problem. Do I need to do anything before installation since hard drive is SATA 500 GB or can some other hardware cause this problem?
