Computer problems

2 days ago, I set out to upgrade my computer. I had some problems. I broke the graphics card
and needed to have it repaired. So yesterday, I was off-line. Today everything is running fine. I
upgraded the memory from 2 to 4 GB and I added a 5oo watt power supply to replace the 300
watt supply I had. In the near future, I will replace the graphics card. The computer is now running fast and quiet.
