I have just replaced my computer's motherboard and CPU, from an ancient ASUS model (too old to even be recognised on the ASUS website) and an AMD XP CPU (1.1GHz) to a new MSI K8T Neo motherboard with an AMD Sempron 2.0GHz processor, both brand new. I thought that it would be possible to use all the other components until I can save up enough for a new graphics card, RAM etc.
All of the other components seem to work fine. After making all the connections and starting up for the first time, Windows (XP) loads successfully... but VERY, VERY slowly.
About an hour after loading, I finally manage to right-click on 'My computer' to be told that I apparently have "AMD Unknown Processor - 2.0 GHz" and "64MB of RAM".
This is what surprises me, because in the DIMM ports at the time were three 256MB PC2100 DDR sticks, all three identical - two which were in the motherboard I had before (as identical as can be - sequential serial numbers and everything), and another one from another PC purchased at around about the same time. So not only is the PC not recognising that it's actually got 762Mb of RAM stuck in it, but it's creating 64Mb out of nowhere!
I've tried swapping the sticks around and taking some of them out - no change, either in the display or in overall performance. I had a look through the BIOS (wiht the instruction manual close to hand), but nothing jumped out at me - and I really don't know what I'm looking for!
Really confused! Any ideas what's going on? Any help would be much appreciated.
