Windows 10: PC Ram Increasing/Decreasing weirdly.

Hello everyone, I have posted about this issue before but no one gave a correct tip on how to fix this. So basically, my electricity was taken for a few days, and when it got back, I had to print a few documents and to my surprise, when I booted up it casually said "Memory decreased F1 Resume F2 Setup" I have a American Megatrends Motherboard and then, i had 8gb ram. I looked at resource monitor, and to my surprise, 8233MB Hardware reserved??

Increase/decrease levels of text in PowerPoint

In Powerpoint, to increase/decrease the current line of text to the next higher/lower level I have 2 options:

1. Click to the left of the line and then press Tab / Shift-Tab

2. On the Home tab, in the Paragraph group, click the Increase/Decrease list level button

For a few months I have realized that in some documents I can do it, but in others I can only do it with option 2. Why can't I continue using option 1 (it's faster for me)?
