I began to study the resource monitor because there seemed to be too much disk activity on the computer next to the phone in lab 403.

I tried to install Microsoft Office 2010 64-bit on the computer in lab 405, but the DVD drive would not work. Dr. Jones wiped the DVD with a handkerchief, but it still would not work. He said I would have to install Office from the computer next to the phone in lab 403, using the network to communicate with that computer. I shared the DVD drive with network computers and changed the network to a work network, but the shared drive folder was not accessible from the computer in 405. I turned on file sharing in 403, but that did not help. Then I realized that the computers in 403 and 405 had the same name, so I changed the name in 405 and added the computer to a new workgroup. I added the one in 403 to the same workgroup, and after restarting the computer in 405, the shared folder was accessible.

Dr. Jones showed me how to remove computers from their rack, starting with Geo 4 I think. But I probably started work on Geo 2 instead of Geo 4. He wanted me to remove and discard the motherboards of those computers but keep the memory. I started disconnecting cables from the motherboard and unscrewing it from the case, but I was not sure what to do about the PATA ribbon cables. In the computer in 405, I had tried to disconnect the ribbon cable from the motherboard, but it was too firmly attached to come loose. I thought it might not be meant to come off because it was an essential part of the motherboard. Maybe removing it would damage the cable or the motherboard. Then Brendan came and showed me what to do. He disconnected the ribbon cables and removed a bracket above the motherboard that would prevent it from coming out. After that, I knew how to remove the motherboard. I tried to remove one of the processor fans and its heat sink, but when they would not come off I decided to leave them on the motherboard and throw it away.

I vacuumed Geo 4 outside and inside before removing the motherboard. I had also vacuumed Geo 2 when I was working on it. When vacuuming, I kept my hand on the grounding mat to avoid any destructive electrostatic discharge.

Next Dr. Jones had me start working on nod 22. He disconnected the power and Ethernet cables and we removed nod 22 from the rack. This time because of my experience with the Geo nodes I had no trouble taking out the motherboard, memory, and expansion cards. The hard drives were more difficult to remove. There were four of them in two bays. One of the bays had been next to the motherboard and just had to be unscrewed from the case, but the other was linked to the bay for the floppy and CD drives. The other bay had to come loose before the hard drives could be removed.

When I finished emptying and cleaning the nod 22 case, Dr. Jones showed me how to install the motherboard, CPU, CPU fan, and memory. Dr. Jones said the motherboard should remain in the anti-static bag as long as possible, and when it comes out it should be on top of the bag while you install the processor. He said it is important not to touch the pins in the place where the processor should sit. Also, I should hold the CPU by its edges not the upper and lower surfaces. The arrow on one corner of the processor should be aligned with a similar marking on the motherboard. After installing the processor, he installed the CPU fan. The pins for holding the fan to the motherboard are difficult to work with. When one goes down, another one or two pop up. Dr. Jones said I should turn the pins in the direction opposite to the arrow before turning the way the arrow indicated.

I took the motherboard out of nod 22.
