I am using some of my old parts to upgrade my mom's computer. Her old comp was a 900 MHz AMD Athlon Duron, 512 MB Kingston ValueRam, WinFast nVidia MX2 and a 120 GB Maxtor HDD 7200 rpm 8 MB buffer with a 1st Mainboard mobo that is about 4 years old. We installed Windows XP Home w/ SP2 on it but the computer ran fairly slow, thus I wanted to upgrade it. I just upgraded my comp and therefore, used my old parts to upgrade my mom's computer. Her new parts are an ASUS A7N8X-X mobo, an AMD Athlon XP 2700 and 1 GB (2x512) PC3200 Kingston ValueRam. The video card and HDD are the same but the HDD is only a little over a year old. Everything is hooked up right and seems to be running well except I get a blue screen when the comp tries to run Windows. The comp starts up fine until it goes to load Windows, then I get a blue screen, and it happens so fast, I can't read it so I have no idea what is causing Windows to not load. I am pretty sure this is a Windows problem and not a hardware problem. Any ideas? Does Windows not like having a bunch of hardware changed out? Also, how can I get Windows back, IF I can get Windows back. Please help, my mom will kill me if I lost all of her files. ![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
