Ok, I just got done building my sisters computer. I got her a barton 2500 thats running on an EPoX 8RDA+ motherboard with a twinpack of Corsair XMS3200C2PT memory (2*256) in Dual DDR mode. Ok, so I try to install W2K. The installation is marred by a bunch of read errors, except it always happens on a different file each time. I swap disk, CD-Roms, cables, everything. Nothing works until I only have 1 stick of RAM in there. So once W2K is installed I put in the other stick in Dual DDR mode. All the sudden files or corrupted and can't be read within windows. I take out one stick, and its fine. So here is my question to all of you, what is the trouble maker? The memory or the motherboard. Please help, because I just want to get this computer off my kitchen table as soon as possible 😉 Thanks.
