Recently, while in a big hurry to get a lot of work done before leaving on vacation, my computer started up with a blank screen. No mouse, no images, no text, no error message, no nothing. I had no choice but to just shut it down using the on/off switch. I then tried to start it again, this time watching very carefully to see what happened (I was getting coffee the first time). It went through the BIOS start (black & white screens with text) OK; then gave a brief color flash of the Windows XP logo, then nothing. The hard drive activity light was flashing so I knew the machine was trying. I was encouraged by the Windows startup sounds, but never got an image.

I recalled that the evening before I had received a warning from my computer security software that some program was trying to make a change to something it thought was a danger. I was in a hurry and I OKíd it without reading it thoroughly. Thinking back I decided that perhaps I had OKíd a bad thing that resulted in changing some setting in the operating system (Windows XP Home). I then crossed my fingers and tried starting the machine in Safe Mode. You do that by turning on the machine and then repeatedly pushing the F8 key until you get the black & white screen that lets you select the startup mode. Using the arrow keys I selected Safe Mode and pressed Enter. I lucked out and it started in Safe Mode.

Once in Safe Mode I decided to restore the system settings to an earlier point in time when everything worked correctly. In Windows XP every time you shut down your computer it takes a snapshot of your operating system settings and saves them into what is called a restore point. If you later install a program or get attacked by a virus that alters your system settings such that the machine no longer runs right you can in theory go back to some prior point in time when the machine ran correctly and restore the settings to what they were then. Thatís called a restore point. Note that you have to uninstall the offending program or get rid of the virus before you attempt a restore. Otherwise the program or virus will just alter your settings once again. Also note that going back to some prior restore point will not delete any files you created and saved after the restore point you select. You wonít lose any data. However, I had never tried this before so didnít quite know what to expect.

In order to get into the routine you do Start, Programs, Accessories, System Tools, System Restore. After clicking System Restore you select Restore my computer to an earlier time, and then follow the prompts. The routine lets you choose a date you want to restore to. I had to think about that. It ran well the previous day, but that was the day the settings were changed. I chose to go back 2 days to be sure I was well before the bad thing occurred. I finished the restore procedure and the machine restarted perfectly. It turned out to be a really good use of the restore point feature in XP.

I mentioned above that you must first get rid of whatever changed your settings in the first place before you do the restore. If you donít then you risk that it will simply alter your settings once again and youíll be right back where you were with a sick machine. In my haste to fix my computer I didnít take that corrective action, so when it restarted the malware once again tried to alter my settings. And once again my security software caught it and presented a warning. Being a bit smarter this time I clicked on Deny instead of Allow (OK). After the machine came up running properly I used my security software (Zone Alarm Security Suite) to do a full system scan for any malicious software. It did indeed find one bad thing (in addition to several spyware items), which I told it to remove. I guess that was it because I have had no more trouble. No, I canít tell you exactly what the offending malicious software was because I didnít write it down, and I have slept since then.

I learned several lessons from this little episode. A good suite of computer security orograms is worth every penny you pay for it. Even cautious computer users like me can get caught up in a virus problem. When your security software presents a warning you need to pay attention; I wonít be so quick to click on Allow in the future. Finally, the System Restore feature in Windows XP is worth its weight in owl feathers. It is easy to use and very effective under the right circumstances.
