Thank you both for the suggestions. Someone at my WordPerfect forum also suggested trying the monitor on another computer or trying a different cable. I'm not sure there's anyone I know well enough to ask. Possibly one of my customers.
As to the 2 HDs, I've heard that if something is to go bad with a computer it usually happens right away, so I'm guessing that the 1st replacement HD was just a bad one. I'm close to 2 weeks on the 2nd one and all seems good as far as that is concerned!!
There was a brief time after I installed the 2nd Service Pack for WordPerfect 12 when it was good. And, as mentioned originally, for a short time after unplugging everything for the storm, when it first came up it was fine--then very shortly afterwards went bad again.
I don't know that I'm so calm!! While waiting for the first HD to come, I managed to get it to work in Safe Mode, so I was able to get some work ready, just not print it. I also did a complete backup so that almost everything would be in the proper folder and I wouldn't have to copy a WHOLE LOT of individual files into my previous backup. And, I was able to learn what to do to copy my e-mail, fax, bookmarks, address book, etc.
The drive came, I called for installation help, and we apparently didn't understand each other about which screw to remove in the back. I couldn't open the computer!! He was going to have me wipe the old one and try to reinstall on that, but when it came up---all was fine!!!!!!
About 3 days later it failed completely. I took the computer to a nearby repair place to learn how to open it; I had been removing the wrong screw! So, I got the new drive in, Windows reinstalled, my major programs up and running, was getting caught up on work, and then that drive went bad after the 1 day. They promised a "priority shipment" but sent it regular ground, so I was without anything for several days, just when I was getting caught up with my customers' work - so I was anything but calm then!!
