The usual gaffe on such a list is the lack of a power supply. I'd use a 450Watt PSU to get by. As to the RAM, the Nforce's require specific memory sticks. Did the supplier help you with this?
Here's the new hardware I bought:
nforce2 ultra 400 ga-7n400-L mobo
xp 3000+/400 barton
geforce fx5900 xt
4 sticks of 256mb pc-3200 viking
When I boot up nothing happens. It's like the video card isn't even there. When i replace the mobo with my old one, it works (sort of).
What I think is happening is that the video card is set to 2x agp and the mobo doesn't support 2x. But i cant see the bios so i cant set it to 4x.
Thats the big problem, another is when i replace the new mobo with the old one i can boot into windows but it will only recognize 128mb of ram. Which is really strange because i have 4 256mb sticks in it.
thx for help guys
