I recently put together a system with the 1 gh T-bird Athlon with SIS730 chipset. I have the M810LMR board from pc-chips. I have a refurbished iomega 12x burner. I was having problems with my system just restarting randomly when doing different things in all different apps. Also, my burner would burn for like 2 secs then stall, and repeat that process taking forever to burn. It often gave me buffer under runs, when the drive is burn proof. I thought it was the drive so I sent it back and got a different one and it did the same thing. I flashed the bios and the problems continued. I don't know what to do. The power supply is a 250 and I have 384 mg of pc 133 ram from mushkin (cl 3).
