It became time to reinstall windows as I was running out of space and my sound card wouldn't work and windows had some quirks I wanted to get rid of. I also added 2 new W/D HDD's in raid 0 and a new vid card for the aging agp bus. I now have a little over 1Tb of space. My new install went on the nvidia raid controller my old install was on the silicon image controller-- that partition I deleated but left the old Hdd's there. My problem is with installing the MB drivers. The cd that came with the MB will not give me the option of installing anything but the silicon image drivers. No chipset driver no ethernet controller drivers or anything but the silicon drivers. I've downloaded the drivers from gigabyte but the machine will not run them. It sees them as DOS files and when I double click on them a black Dos screen comes up momentarily then goes away and nothing happens. I've tried to go to device manager and reinstall them manually from the cd but although sometimes the cd spins up and the lite flashes there is no id of the Hardware and no installation of the drivers. I'm beginning to think that the MB chipset is slightly fried. Slightly as I could install windows and it posts. Am I forgetting something? Or is this a Hardware problem? I do have a rma'ed MB that I have not used since it came back from gigabyte. Do a search of christmas tree lights and you'll see the problem I had with that board. It's a lot of time and energy to put that in tho and I don't want to do it unless I really have a Hardware problem There's no guarantee in life is there? Thanks for any ideas or comments!
