Recently (within past week) no new software, no hardware changes, etc.
Upon Boot - After Dell, After Windows 'starts up'.....while my programs and taskbar are loading the screen gives approx 3 snap-fast flashes then settles. It orig. started as one flash, now has gone to more. Don't want to ignore if one of my hardware parts is telling me something.

Help. Thank you. Nan
