Just got the MSI KT333 with PC2700 RAM + a Maxtor ATA133 HDD. Using these components plus my GF2 GTS and a second HDD with is ATA100 I build a WinXP system, and it crashed on me occationally and randomly. If I left the machine idle nothing will happen (yet), but sometimes when I played a game (Monopoly Tycoon) it just rebooted the system! Games like Jedi Knight II ran fine. I tried to transfer 9 Files in total of 5GB over the LAN it worked but when I transfer 20,000 files (1GB total) between two HDD it crashed twice. Sometime out of the blue, for example browsing the web or browsing the HDD content the system rebooted. I suspect something wrong with the HDD interface or the new ATA133 chipset. Anyone has any experience?
