Okay, I am trying to build a new machine and I am having massive problems... Abit SG-80DC motherboard w/Intel Pentium D 840 2 DVD burners 1 hitachi 160MB SATA hard drive ULTRA 400W power supply ULTRA DDR400 PC3200 RAM (1 stick, 1 GB) when I first set it up, I couldn't install windows XP from the CD. It would load all of the drivers, ask if I want to perform a new install or repair. I would choose install and it would reboot... but not always. Sometimes, it would get as far as the license agreement and asking me which hard drive partition I wanted to use before rebooting. So...inconsistent. I have tried: using 2 512MB DDR sticks from my old machine. Same result. unhooking all unnecessary devices. Same result. unhooking the new sata drive and hooking up my 2 old Parallel drives, which work fine in my old system. This time, I get a screen telling me that my configuration has changed and asking me how I want to boot... If I boot windows normally, I get the blue screen of death. Restart...same thing. If I boot in safe mode, I still get the blue screen of death. If I leave it on, it will repeatedly try to reboot and repeatedly give me the blue screen. So, it seems like it is a hardware issue of some sort. Bad motherboard? Bad processor? bad power supply? I don't know. Do I need to try flashing the BIOS? HELP!!!! Thanks, Andy.
