One technical issue I had was on Windows 8.1, with the charm menu not working. The troubleshooting steps to fix it was I did CTRL+SHIFT+ESC to open task manager. I then found Windows Explorer and clicked "Reload." Then everything was fine.
Hope This Helped!
Disk access is way slower than
memory access. Caching is a technique to improve the disk access time. Block cache is a caching technique which
reduces disk accesses time. Here a
portion of disk is bought to cache for reading and a modified blocks are first
changed in cache but reflected in the disk at one go. On the other hand with write through caching
each modified block is written to cache and at the same time it is written to
the disk. Write- through caching
requires more disk I/O so they can have a negative effect on the performance.
The issue would be that the memory was not installed or was not detected by the system. If this happens, the system boot will fail and a beep code is heard. The system would not show anything since all of the software are in the memory which was not installed or detected.
