Intel i7 CPU
6 GB ram
Starting a few days ago, my computer has been booting up extremely slowly. The computer enters the windows loading screen (black screen with green loading bar) and takes approximately 4~5 minutes to load. Following that, it goes into a completely black screen for another 5~6 minutes. The mouse cursor then appears and it hangs for another 3~4 minutes. The log-in screen then appears and everything else seems to be fine.
I originally suspected a virus, so I tried booting up in safe mode, but it's still incredibly slow and it seems to take a long time to load crcdisk.sys (or something similar). I also tried booting up with the bare minimum start-up services with no success. Yesterday, I also defragmented my drivers, but against to no avail. I also checked to make sure that there wasn't any loose hardware (hard drives or w/e).
Recently, I've been having an issue with opening task manager. For some reason, I can see the task manager icon on the taskbar, but I can't seem to make the window appear. The mini-window that appears when using alt+tab to switch windows also doesn't appear. Also, I have had a random, blank window that seems to be loading something. I took a screen shot to show what I'm trying to describe.
EDIT: Forgot to mention, but I tried a system restore and it didn't do anything either; it said there was an "unspecified error."
