099 - My Windows7 laptop dies

My Windows7 laptop dies
===
Date of Windows crash = The morning of Saturday May21,2011. There is some strange Karma today. This day is the prophetic Doomday/Rapture predicted by the religious people at www.familyradio.com . At Calgary International Airport, many experienced inconvenience as there was a ??power/computer?? disruption. This is also the Victoria Day long weekend (Monday the 23rd is Victoria Day). Thus the airport would be more busy than a typical weekend.

My Windows7 laptop dies. Windows states there is an error, likely an "incompatible driver". It starts into a self-diagnosis, and then suggests:
1) checking disk for errors. I do this as prompted. I am unable to boot into computer;
2) use last known good configuration. This fails. Windows can't do this;
3) use system restore. Windows says it can't find a system restore point. This is funny because I always keep at least 1 system restore point on the hard drive. Also, system restore is automatically active, by default, for the C:\ drive in a Windows 7 computer.

Now, I try booting into "safe-mode". This fails because, once again Windows says there is an incompatible driver.

One day prior, (ie., Friday May20, 2011), there was a reminder on my computer to install an Adobe upgrade, probably for flash or shockwave. I click OK but nothing happens as Adobe tries to connect to the internet and cannot find the connection. Also on this day, before shutting down, I had cleaned the drive C:\ simply by right-clicking on the drive C:\ icon, then on the Properties, and next choosing the Disk Cleanup button. This was straightforward and the process only took what seemed to be 1-2 minutes.

Two days prior (ie.,Thursday May19, 2011), at the public library, WiFi was very slow. My current antivirus software was, as usual, turned on.
(Come to think of it, my WindowsXP laptop similarly experienced a fatal "lsass.exe error", almost 1 year ago, on the evening of Tuesday May25, 2010. During the day, of May25,2010, I was also at the public library on their WiFi network, and my antivirus software was active too.) What kind of a coincidence is this?!
There is something else that is similar that may have occurred on these 2 dates. I may have intentionally or unintentionally switched wifi networks without shutting down the browser first. Windows may report an error with a router conflict of address or connection or similar jargon.

Back to the WindowsXP laptop and the lsass.exe error. No one seems to know exactly what an lsass.exe error is. I ask the computer technicians at the big chain electronics retailers and they don't know. The web has information that it is a software error resulting in a registry corruption. Other web sites claim that the lsass.exe error is due to a virus. Approximately, from the year 2007 to the Summer of 2009, this laptop has several times, encountered the lsass.exe error at the startup/boot stage. This was always remedied by my choosing the Windows-XP choice of using the "last known good configuration" or by restoring the registry via the ERUNT/ERDNT app (Written by Lars Hederer), using a (BartPE)live-CD. In the Summer of 2009, the CD-drive breaks down, so I am no longer able to restore the registry by this method.
In the Autumn, on September 06, 2009, the lsass.exe error strikes again. All Windows could show was a small box saying there is an lsass.exe error. If you click on the "ok" button, the laptop reboots & goes into this vicious cycle again. Now that I can't use the cd-drive to restore the computer, I had to use the services of the computer technician for a pricey $ data recovery and OS re-installation. As indicated above, the lsass.exe error happened again May2010 and the laptop remains dead.

I'm so cynical about Windows. As for my Windows7 laptop, I used the manufacturer's proprietary recovery software, and it worked like a charm. I did lose some data, but most of it had previously been backed up and my losses were minor. It's funny how Windows has frustrated me so often (ever since Windows 98), and yet reliable hardware and software all seem to come from non-Microsoft Brands or Corporations!

Conclusion
----------
Things which I speculate may cause Windows to get a major/fatal booting error:
- lsass.exe error;
- switching wifi networks without first shutting down the browser;
- trying to upgrade Adobe Flash player (or Shockwave?);
- Using Windows' Disk Cleanup feature;
- some unknown virus which strikes in the month of May? (note: I don't know if I got a boot error in May of 2009/2008/2007; I don't have it documented. If the error did occur annually, that would be freaky.)

The only preventative measures I can think of for boot errors:
- frequent antivirus updates;
- don't switch wifi networks without first closing your browser;
- don't update your Adobe software, unless you absolutely must;
- make frequent/regular backups of data
- avoid cleaning your hard-drive using Windows' Disk Cleanup button;
- don't totally rely on Windows' System Restore feature. It has failed me several times on two different machines, and with two different versions of Windows.
