Hello Digerati, always good to meet another fan of Tolkien.
Well the Sfc /scannow never flagged that it encountered anything, but I did run it three times just to be sure.
As for the Text, thats a bit of the random part, its not just the text I have typed, but names in Messenger lists, browser pages, icons, sometimes part of the clock display. Even highlight the area where there is text will show that theres something there taking up space , but the letters remain invisible. This problem is always slow in cropping up. Or at least has been, you walk away for an hour, come back and then text is missing. or Turn off the monitor for the night turn on the monitor in the morning and text is missing. Its never been instant. However once the disappearing occurs new text entered by me or sent to me via a messenger is also fully possible of disappearing. There has been one instance where most desktop text icons and the like had vanished but one icon's text had changed to a transparent black almost like a shadow of the text.
As for Safe Mode I have not dropped the system down into Safe mode yet to see if it happens in Safe mode. Although I may drop down the system and shove it into Safe mode tonight and see if when I get on it tomorrow if the text is missing in safe mode.
The last time the interior of the Tower was cleaned was about a month ago.
Well I know with the power supply Idea I am not so lucky. As my Power supply stock pile are pretty much too old for my current Mobo.
The Ram testing I can do easily enough yank one stick and see if it effects the issue or not. But I'll try the drivers first hopefully that will satiate the evil of my tower. As well that should negate the last of the software possibilities.
