Hello

I installed xp sp3-final on my dell optiplex GX260 after I increased the memory to 1536MB (512+1024) with a 2.40GHz processor. The HDD is 80GB and my system freezes unnecessarily. Sometimes I have to shut it down manually.

Before installing sp3 I was using sp2 which I did not format, so both OS are still on and I have to choose on startup which one to run. The sp2 cant support lots of programs that's why i installed the sp3 but get nothing but freezes. Please what could be the cause of this freezing since I think the memory and processor and HDD are all ok for a maximum speed and operation. Thank you.
