Long story short, I have effectively increased the physical RAM on my laptop (2003 Dell Inspiron 5100) from 512 Mb to 768 Mb, but not to 1 Gb as I had expected. I will live with that.

I am having trouble getting a virtual machine to access new discs. It errors saying the disc is either corrupt or formatted in some strange way. News to me since I thought formatting was just formatting. Discovered several formats like 1.00, 2.00, 2.01, etc. I tried all I could find but just kept...

KB 2670838 - The EVIL UPDATE This Windows 7 update wasted a lot of my time today. I could not find my own postings in the past... maybe I was unsure in the past... I am still unsure today.. but much more sure than previously. When installing IE11 I suspect this patch also gets installed. This...

I have finally decided to bite the bullet and build my own desktop. I am looking for sources where I can read about what others are doing while building their systems. I must not have used the right search word(s) because I did not find a usenet group that is oriented towards computer builds....
