Before I continue, I want to show why this has been such a trying experience...I have had a home computer since 1979. I have been building desktop computers since 1997. I worked with computer hardware professionally from 1980 to 2004.
Working with computers has been very challenging in recent years because I suffer from chronic fatigue. Right now, my vision is dimmished to the extent that even with reading glasses and a magnifying glass, things are still a little blurred. I will be getting laser surgery in December. After that I may also need prescription glasses.
I want to thank everyone that took the time to help me with my problem. I have decided to reinstall the Scythe Mugen 6 and return the Cooler Master 240 Atmos to Amazon.
While reading the instructions for reinstalling the Scythe Mugen 6 I realized that I had installed it backwards in January. I had the fan on the back instead of the front of the cooler. Putting the fan on the front gives more room to access the PCIe release lever. Since I have already put the computer back together I have not been able to test this.
After I put the computer back together I had a couple problems:
Problem #1: DVD does not show in File Explorer. However, it is seen and can be accessed in Disk Management.
Solution #1: In Device Manager uninstall IDE/SATA. After scanning for changes this device comes back. The DVD now shows up in File Explorer.
Problem #2: Neither USB 3.0 ports on case front panel are working.
Solution #2: Opening case revealed 20-pin USB 3.0 connector had been unplugged. Plugging it back in motherboard restored USB 3.0 front panel ports.
Problem #3: DVD had disappeared again in File Explorer.
Solution #3: I had to repeat the solution #1 again.
Note #3: The motherboard and CPU had been upgraded in January. The system went from AMD X370 to a B550 chipset. I did not reinstall Windows. I suspect a clean install of Windows 11 will be necessary to clean up bugs like this. This will be done at a later date.
Photo #1: Computer case front. Note the following:
The orignal 140m case fan has been reinstalled
The 2.5"/3.5" 2-drive bay has been reinstalled
The 5.25" 2-drive bay has been reinstalled
The Blue-ray/DVD burner has been reinstalled in the 5.25" bay
Photo #2: Inside the computer. Note the following:
The 5.25" and 2.5"/3.5" drive bays can be seen on the right
The Scythe Mugen 6 CPU can be see on the left. Note the fan is now on the right side.
Photo #3: Details inside the computer. Note the following:
The PCIe release lever can be seen. Hopefully it can be reached now.
The 20-pin USB 3.0 connector can be seen without the front panel cable plugged into it.
The original intention of working on my computer was to upgrade the two internal M.2 NVMe SSDs.
MBD: ASUS ROG Strix B550-F Gaming WiFi II
M.2 SSD slots
#1: supports PCIe 4.0 x4 & SATA modes
#2: supports PCIe 3.0 x4 & SATA modes
Old drives *
#1: XPG SX8200 Pro (2TB) (TLC; PCIe 3.0 x4)
#2: Intel 660p (2TB) (QLC; PCIe 3.0 x4)
New drives
#1: Samsung 990 EVO Plus (2TB) (TLC; PCIe 4.0 x4)
#2: Samsung 990 EVO Plus (4TB) (TLC; PCIe 4.0 x4)
Photo #4: Comparison of the old and new SSD speeds.
Note the new SSDs are faster than the old ones.
I didn't test the boot speeds before and after but the computer seems to boot faster.
