Bah and I had to re-register my account after 2 years. Hello all. I just put in a new Abit IS7-E with a Pentium 4 3.0GHz and 1GB of Corsair TwinX XMS PC3200 RAM. No other changes were made and after the computer POSTs it reboots. Sometimes I can see a blue-screen-of-death. (Windows XP Pro SP1). The CPU is hanging around 115 degrees F, which is normal. And both modules of memory passed memtest86. Do I need to reinstall Windows? I also tried both 4X and 8X AGP to no avail. I've done this to other computers I've built (thrown in new cpu/ram/board and everything still works fine). At a loss of what else is wrong. EDIT: 400W Antec Power Supply and latest BIOS revision. Thanks for any help.
