This computer is one that our pastor wanted me to bring home to see if it could be upgraded enough to do streaming video on you tube., It's a Dell Optiplex 360 with an Intel core 2 duo processor and 3 GB RAM. It says on the case that it has Vista on it, but it has XP Pro. When I first turned it on it came to a previous secretary's user page. I was unable to get past that, so I reset the BIOS. First of all I had to really clean it up good inside and out. It hadn't been used in a while and was full of dust etc. Now when I turn it on it doesn't find my HD or DVD. The HD is first boot in the BIOS. I ran the system start up tests and they came back ok. I can take the HD out and piggyback it up here to mine and I can see all the programs, so know it's not a bad HD. I would appreciate any suggestions as to what I should do next.
