Hi there. I've been having some trouble with my computer for the past few days. It's quite hard to describe what's going on.
When I boot up my computer, it seems to work okay for a few hours... then it slows down and when I try to open the task manager it gives me an error. At that point, the computer acts as if all it's memory is being used and when I open a window or errors pop up, they have transparent backgrounds or buttons. Also, while in this state, if I try to shutdown, the window is also partially transparent and a weird window pops up when it begins the shutdown. It may have also given a few unresponsive program errors.
I currently have Avast as my primary anti-virus program, and I use Malwarebytes from time to time to scan as a back up. I ran a boot time scan with Avast, which removed one file... but otherwise, no full/quick scans with Malwarebytes or Avast have found any threats. I also ran combofix... which seemed to make things a little better... but I still get errors after the computer has been used for a while.
One last thing to note is that when this first happened and after I rebooted, the standard yellow "windows security update" icon came up, but disappeared before the computer finished booting up. Well... it came back again after a few restarts after virus scanning, and it installed 2 of 3 updates. It said the 3rd could not be installed. When I booted down, it went through the "installing" process prior to shutting off, giving me the standard message "do not turn off your computer or unplug it, it will shut down automatically."
Not really sure what could be the problem here... but I'd greatly appreciate any insight or help that could be provided. Thanks so much!
