System info: Dell Inspiron desktop, model 531, running Vista (yeah, I know). Monitor is a Westinghouse LCD.
So I'm on-line watching mindless crap on youtube, and my screen goes blank and flashes a "no signal" message, though my computer is still on. So I reboot; as it's shutting down a blue screen o' death flashes by too quickly to read, though I did note the phrase "attempt to reset display driver." The boot proceeds and I still get a blank screen. So I reboot in safe mode . . . and everything is fine.
Then I tried a system restore, and booted in normal mode: another blank screen. So I once again boot in safe mode and, since I have no idea what else to do, I contact the Dell support desk (the machine is only 3 months old). The guy installs a new video driver; the problem persists. He then tells me to run a diagnostic on the video card and they'll call me the next day. I run the diagnostic. It says the card is fine, which isn't really surprising given that the monitor works in safe mode.
So . . anyone have any ideas? Clearly something that happens in the normal boot but not the scaled-down safe boot is doing something naughty, yes?
Anyway, any suggestions would be greatly appreciated.
