I changed the CMOS battery to a new one 5 months ago, and over the last few days the PC fan has been constantly very loud, and now recently i have lost sound.


Another problem is, Windows updates don't seem to be updating.


Would these problems be linked to the CMOS battery?


Please Help.

- Windows Update is "causing problems" lately.

- Open Task Manager (Processes tab) and let it show EVERY running process. Open Task Manager (Services tab), highlight "Wuauserv", right click, select "Go to Process". Then Task Manager opens the "Processes" tab again and highlights one of the "Scvhost.exe" processes. If that one process uses A LOT OF CPU then you've got a "Windows Update" problem.
