Dell Dimension XPST7r PIIIE 700MHZ 385MG RAM WIN98SE
All sorts of seemingly unrelated problems suddenly emerged on my customers Desktop perhaps 2 months ago.
When the system boots there's a broad dark band across the middle of the monitor. This happens both using his monitor and mine.
NVDIA GEforce 256 AGP Dell video card. I upgraded the driver and it still does this.
Message "EMM386 not installed."
I eventually tried selective startup without either the autoexec bat or config sys coming up at boot. No difference.
Looking under performance it says: Disks Running in compatibility mode
Drive C is running in Dos compatibility mode (something like this.)
I put in an ethernet adapter and plugged in a cat5 cable. The little green light on the adapter lights up, but at boot the system doesn't recognize there's a new device out there.
Tried several scanreg /restores
Tried the system file checker
Ran Adaware, Spybot, and hijack this. Found some stuff, but it didn't make any difference.
