First, it appears that your CMOS should be reset. Go into your BIOS when your computer first turns on, load default settings, save, and exit. I would suggest also resetting the software connections between your BIOS and hardware and clearing your temporary memory. To do so, follow these steps:
1. Shut down your computer
2. Once the computer is turned off, unplug all power sources (AC Adapter then Battery)
3. Hold down the power button for 30 seconds
4. Plug power sources back in (Battery then AC Adapter)
5. Turn your computer back on
(disregard the battery statements if you are using a desktop and not a laptop).
Also, you may have some corrupted system files. Run SFC /SCANNOW Command - System File Checker
Use your system normally for a day, and then post back your event viewer application logs again.
If that does not resolve some of the issues I see, I will give further suggestions.
Specifically, you have errors with svchost.exe_SysMain and SearchIndexer.exe, which lead me to believe that there are either corrupted system files, or a memory module issue, or both. The above steps for resetting BIOS issues should fix any BIOS related problems, which may fix memory module issues.
