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. The HDD has WinXP 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 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. This seems to be a Windows problem (and this thread will also be in the OS forum) but I am posting this here just to make sure there is no hardware problem. Anyone think there is a problem with the HDD or something?
