I recently tried to troubleshoot some errors I saw in the event viewer. I forget what the feature is called, but windows has some startup option that will check your drivers for the right signing or something like that? So when I tried it, windows started failing to boot. Not knowing that I could disable the startup program again from safe mode, I instead did a refresh from my disc.
Thins seemed to go well after that until I started reinstalling Norton 360 while windows update was going at the same time. Windows froze up for the longest time, then I got the BSOD and when the computer rebooted itself, my computer couldn't find anything to boot. I checked BIOS and my hdd was missing from the bootup list. I was able to put it back in the startup list, and things were normal from there.
Got all my updates and everything, Norton seems to be working. But about once a week or so, usually while I'm web browsing, my computer starts to get super slow, and sometimes it eventually hangs. Sometimes when it hangs, I can wait it out and it'll recover. But sometimes, I get the BSOD again.
Now, when it happens, my hdd is missing from bios altogether, as if it is not connected. But, if I shut down, and power back up, it'll be start right back up without me even having to go into bios.
Do I have some bad hardware maybe? Or maybe some kind of malware getting into the RAM? Or is windows messed up?
Be advised that chkdsk /r can take a while to run. If there are errors, it can sometimes take hours to run, but you must let it run to completion - don't stop it or turn off the PC. So be prepared to be without your PC for some time.
Open an elevated Command Prompt (Run as administrator) and type (without the quotes) "chkdsk /r"
You'll be informed that it can't run and asked if you would like to run it on the next restart. Type "y" and then exit the Command window. Restart your PC.

So I did what you said. Strange thing is the scan barely took long enough for me to notice. On the loading screen all that I saw was "Scanning and repairing Drive C: 100% complete" It was literally a minute between hitting the power button and seeing my desktop.
I also have run Western Digitals HD health program. Did both the short and long scans and passed both.
I'm not sure, but I THINK the problem I described usually happens when I'm recovering windows from sleep mode. Within minutes of recovery. It's possible that it has happened other times after waking up from sleep mode but it took so long that I forgot if it could have been related to it. Does that make sense?

Tried again and it's now on 10% on the scan for about 10 minutes now.
What happened the first time: I saw the box you showed with all the same warnings. Typed y. Was told to restart. Hit restart and went to the bathroom. Came back nothing happened. I frequently have programs that wont let a shutdown happen, sometimes the os will stop trying to shutdown/restart and show the desktop back by itself.
Anyway I had to close iTunes and then decided to shutdown. I powered on again and that's when it showed 100% right away.
I'm hoping all that restart trouble might explain the quick chkdsk. Anyway it's scanning right this time... Hopefully...
Ok so it's done. Looks like it managed to accomplish something. Any idea if it dealt with the problem? Here's the log file I managed to find all by myself with google.

PC is waking up quickly and properly unlike before. Things seem to be alright now. Thanks for the help. Great job.
