I've started having various problems cropping up for a couple month now.. Among them being:
Periodic, random de-selection of the current active window, rendering it seemingly unresponsive to input until clicked on again.
"The Windows Security Center service can't be started."
"windows Update cannot currently check for updates, because the service is not running. You may need to restart your computer." Upon looking for fixes, I noticed that I don't even HAVE the windows update service anymore.
Every time on start-up, an error appears, so soon that the desktop hasn't even appeared after logging in, claiming that string.dll is missing.
Cannot turn Windows Firewall on, as once I attempt to do so I get the message "Windows Firewall can't change some of your settings. Error code 0x80070424"
Also: "There was an error opening the Windows Firewall with Advanced Security snap-in" ... "The Windows Firewall with Advanced Security snap-in failed to load. Restart the Windows Firewall service on the computer that you are managing. Error code 0x6D9."
Task manager used to fail to start. "The program can't start because pcwum.dll is missing from your computer. Try reinstalling the program to fix this problem."
Right before my last system restore, various drivers
went missing or were broken, including, from what I remember, the one that my adaptor uses to connect to the internet. I could not connect either wirelessly or via direct connection with the ethernet.
I'm afraid to restart my computer, lest the drivers break again...
Also I tried running a virus scan with AVG while the internet drivers were broken, and apparently it said I'm missing a driver
to scan too? I have no idea >.< AVG isn't on my computer atm anyway..
I also never received the disc with the operating system on it when I got the computer, so it's not like I can do a complete reinstall or get the missing things from there if that even is an option.
I've tried running the 'sfc /scannow' thing, and it supposedly fixed everything it could, however nothing changed noticeably.
