Acer laptop, Windows XP operating system:
Laptop will boot up in safe mode.
In normal mode...
After the Windows XP logo disappears, when the cursor should appear, the screen goes black with faint vertical lines. When I move the mouse, one vertical line moves left and right across the screen.
If I reboot and start moving the mouse right after the XP logo disappears, the computer will boot up normally.
If I connect an external monitor, the computer will boot up normally, without messing with the mouse at all. If I disconnect the external monitor after it boots, everything works okay.
Any Acer gurus out there who can help with this idiosyncrasy? What would cause this anomaly?
