It's a Dell Dimension 8400, and, without any hardware, software, or any other changes all of a sudden, like overnight, it will not go beyond the choices available using F8 to get into the start up choices menu, it also will not boot using a bootable cd such as acronis back-up software or mem test, or windows disc, or dell re-installation disc and will not boot from a floppy, either.
It also takes an extremely long time to respond to keyboard stokes, although in BIOS keys work as normal; 2 keyboards tried there, and at every step, and also should add that on the screen that does show up, it says no keyboard present, although it does work enough to get into BIOS and the start-up menu screen.
After you choose any of the options, it goes to the Black Screen Of Death, however, after watching said process way to many times, you can see where once or twice the BSOD kinda flickers to a slighty less black for just a moment, before returning to it's morbid dead self.
I have:
checked things in BIOS, everything appears good there, all drives read present and accounted for...
played with the boot order any way possible...
disconnected everything to try to isolate something....
checked memory by plugging one stick at a time into all slots; BIOS beep happens only when there is none plugged in
looked for burn marks or any other evidence of electrical mal-function; none visible...
changed motherboard battery...
set things to default, jumped the BIOS, and set things back the way they were before and after each of those steps...
I haven't:
checked the hard drive on another machine, but i have felt it, and heard all other drives, working, at least mechanically....
checked the memory in another machine, as i feel it's good...
Bottom line is, everything acts as if it is working, but it ain't, so, my questions are:
Has the motherboard taken a partial dump?, and
Is there some sort of virus/malware that could take out an entire system like this? and
Does anyone have any other solutions?
Thanks in advance, folks!
