I am using Windows 8 Pro 32-bit, with a 2 TB hard drive and 3 GB of RAM. I installed Win8 the day it was released in October, and it has been operating flawlessly since installation.
**** BACKGROUND **** Yesterday morning (Jan. 30th) a blue screen appeared with a message that Windows had found an error and was collecting information. At the bottom it suggested the I look up BAD_POOL_HEADER on the Internet to learn more. The computer shut down after a few minutes and rebooted. It took about 15-minutes to regain full operating status. It also apparently downloaded and installed an update. Internet information about BAD_POOL_HEADER stated that it could be caused by a flawed antivirus program. So, I uninstall my AGV antivirus completely and activated Windows Defender, followed by data file updates of same. I also ran a full scan, which found two minor errors that it automatically repaired.
Subsequent to all of that I find that occasionally the screen will, while idle, turn blue for 4-seconds, and then revert to whatever was showing before that. If I try to close Skype, again, the screen turns blue for 4-seconds and Skype remains open. If I click on the File Explorer icon at the bottom left, same thing happens. There are a couple of programs that won't run now, in the sense that I click the icon, it seems to be starting to run, then the screen goes blue, and 4-seconds later returns to my desktop view, and the program I was trying to open is again closed. This does not happen with most of my programs, but it seems only a random few. BUT, it is extremely annoying!
Anybody have an suggestions? I tried System Restore to January 25th, which runs for a while and then tells me it didn't restore anything.
