Description of problem:
The boot problem described below began occurring after going to my homnepage on the Internet using Firefox browser. For some reason, I was unable to get FIrefox to close the pages and get back to my desktop screen. I had to do a <CTRL>, <ALT>, <DEL> to get off the Internet. (Homepage is my ISP log-in screen). After getting back to the desktop screen, I did a restart. This is the point where the computer would not boot normally.
Computer will not boot normally, either a cold boot or a restart. The only way it WILL boot is by pressing the F8 key repeatedly (or the F12 key) while doing a boot. It does NOT present the screen from which to choose how to boot (i.e. normally, Safe Mode, Safe Mode with Networking, etc). It just does a normal boot. I also note a high pitched sound emittting from the computer (almost like the sound a coffee pot on the stove makes as the steam whistles out a vent - just not as loud).
The sound stops after the system finally starts booting in Normal Mode. The system seems to be taking longer to boot, as well as, access the Internet, or go from one page on this website to another. RAM was upgraded from 512 MB to 2 GB a few days ago, and computer performance was significantly enhanced. NO problems like this have occurred before today.
UPDATE: In checking the Event Log, I find the following:
Error: Service Control Manager
The following boot start or system start driver(s) failed to load: MpFilter
Error: The MsMpSvc service failed to start due to the following error:
System cannot find the path specified
Error: Initialization failed because the transport refused to open initial addresses
I have no idea what this all means, or how to resolve it.
Resolution measures attempted thus far:
1. Full scans with Avast AV, SAS, and MBAM. No malware found.
2. Have tried multiple cold boots, as well as, restarts from the desktop with no change.
3. System Restore to 24 hours prior to this incident. No effect.
Any help in resolving this problem would be much appreciated. (System specs are shown below in signature line).
Thank you for your time and help!
