gang I confess this is a Vista-related problem but I need an idea or three.
this is a good fast hp minitower, Athlon x64-based, that I previously CAREfully reworked Vista Business on and had it lean/mean/clean and fast. A year later it needed work - when booting up normally and logging in to the main User account, the display is "fried" - it displays a regular pattern of wavy lines with no image, nothing readable. I cleaned it up and got it displaying normally again. Two days later, issue recurs. No malware, no odd things running in the background. On a second, debug-only account, I log in and everything looks fine, but nobody uses that one.
I'm baffled by what could be causing this? I don't want to just "dumb down" the display settings and hope for the best... that's a non-answer.
is there some issue with desktop-image-display? themes? Aero? sunspots
