Did you have windows running on another hard drive in the system? If so then I would say the memory shouldn't be the problem, but it won't hurt to check.
Do you have to load drivers for the SATA controller? Does it blue screen when loading the cd or is it after the computer reboots and it is running off the hard drive? Not clear from your post.
no i didnt have windows running on another harh drive, i had linux (ubuntu) running on it i still have , no problems. i have tried drivers that i have downloaded but they dont seem to work, cannot seem to find the right ones. my motherboard is an ECS pf5 extreme with a 3gb p4 pro. 2gb memory 256 mb nvidia graphics 80 gb sata hdd (seagate) the chipset is based on the intel 945p (lakeport) northbridge and ich7r. i think it might be something to do with the ich7r, i cannot seem to find them anywhere. i hope there is enough info here for you to help me
