I have a dell dimension 3000 which had an intel pentium 4 2.74 GHz dual core processor which came with 512MB of RAM but I had upgraded it to just over 1G of RAM. I also upgraded the vid card to a Radeon 9000+. There was a storm and my computer wouldnt power up. A tech said he had to replace the motherboard and that he would put in something compatable/comparable with what I had. It now says I have an AMD Athelon(tm)XP 1800+ 1.54GHz, 992MB of RAM. Is that even dual core like I had before? Why is the RAM less now? Also the games I used to play on it I cannot run smoothly, where as before, even before my upgrade to 1G of RAM and the Radeon 9000 Vid Card I could run these games smoother then now. Did he downgrade me instead of matching what I had? Also he said he couldnt get my new vid card to work so he removed it and gave it to me seperately. Is what he gave me crap or what? What should I do?
