Multiple Computer Failures

I’ve spent most of last week dealing with three computer failures. My main (and oldest) computer died; then the backup computer died. Then I bought another one and IT died. They had to wipe my hard drive (which had nothing much on it) and put in a new operating system. Luckily, most of my important stuff was backed up on a memory stick so I didn't lose much (I hope) I spent most of the day today uploading software. I hope everything works right. I WAS able to post a couple of times over the weekend by using my son's computer.
