Yesterday I experienced a very slow start-up. Today I got a BSOD. I am using Windows 7, x64, on a Toshiba Satellite A660-11M and have not tinkered with the hardware recently (changed HDD a few months ago). Here are the dump and sysdata files from the BSOD.
This is how it all happened:
Yesterday: I turn machine on, loads, boots-up to login-screen. I enter my password, and here comes the slow part. Windows Desktop fades in, but I am unable to do much (screen partially frozen). Then, after 1-2 minutes, everything responds again and I get a pop-up from AVG mentioning an error on its behalf (sorry, forgot exactly what it said).
Toady: I turn machine on, Windows boots-up to login-screen, I enter my password and go make some coffee; and when I come back (assuming it took me a couple of minutes) the "Welcome" loading screen with the little loading symbol is still present. After waiting a while, I realize the machine is not responding and shut it down by force (continuously pressing the on/off button). Then I start the machine again, loads up to login-screen, I enter my password - screen freezes and after a few seconds, BSOD.
On my next attempt (after the BSOD) Windows did manage to boot-up completely. However, once in Desktop, I still experienced a very slow performance. I got the usual "Windows did not shutdown properly" message, from which I saved the .DMP and .SYSDATA files (see above).
As the title connotes, I feel this is related to AVG 2012 Free Edition. Because of the peculiar error message I received yesterday, and because today, after the BSOD, the Windows 7 Action Center flag is showing up in the system tray. It says "AVG Anti-Virus Free Edition 2012 reports that it is turned off". However, I do see the AVG icon on the system tray.
So this all seems a bit fuzzy to me. I hope the dump and sysdata files allow you to help me. I would really, really appreciate it. Please let me know if I missed any relevant information, and I will add it ASAP. Thank you!
UPDATE 1: I started Windows in Safe Mode with Networking, and the problem seemed solved. Windows booted fine, Desktop loaded fine. No freezes, no unresponsive Windows Explorer. Because of this, I wondered if the issue could be caused by something else than hardware. I ask this because I am not fully certain as to how Safe Mode works, but from what I know, it still uses the same hardware (just not some drivers). So, again, is there a chance this is not HDD (or other hardware) related?
UPDATE 2: As recommended by user Moab, I ran the hard-drive's diagnostics tool provided by the manufacturer. This tool allowed me to run a SMART test first, which is a quicker, smarter, sort-of "preview" test. The result was that "too many problems were found and thus the diagnostics tool has ended". I then ran the full test overnight, which resulted in this.
I am still looking for a solution and would truly, truly appreciate your help!
