I bought an ECS K7S5A a month ago and am running a AMD Athlon 1.2, 256 DDR, CD-RW, ASUS 7700 GeForce 2 and so forth. Initially I had a real problem with getting to system to work but after a fresh reformat things were ok. My CD-ROM broke so I went out and bought a Creative PC-DVD 12X drive and replaced it. On the system properties folder, the drive seemed to be working. However, when you place either a DVD, or regular CD (data, music...) it causes the system to reset. I've tried moving it from secondary master to secondary slave and nothing seems to help. Has anybody had a similar problem? Any help is greatly appreciated.
