video black death

[nntp.charter.net]

Here's my problem.. I have upgraded to a 128 meg video card from a 64 meg
card. The instructions say to simply place the 128 meg card in the AGP slot
and start the computer/insert the driver CD and install. Well, ONLY the 64
meg card will work on this computer. When the 128 meg video card is
installed, the computer boots up half way thru the Windows splash screen and
then goes black but keeps booting into Windows XP although the screen is
black, the Windows jingle comes on to indicate it is finished booting. I
shut off the computer and put in the old 64 meg video card and shazzam a
good boot into Windows.

Now, I take this 128 video card and put into another computer and shazaam..
it boots perfectly. The card is good.

Fortunately, I ghosted the original HD and when I removed the 64 meg driver
and rebooted... black screen half way thru Windows XP splash screen. In
short, what Windows XP setting did I change to NOT allow me to boot to even
the Safe mode so I can install the new video card?

thanx in advance, Salty

Start Windows in the Safe Mode and reduce the video settings after you
have inserted the new card. Restart to the Normal Mode.

Been there...tried that! That's the mysterious frustration. I have turned
the computer off, installed the new video card and tried to boot into
'every' safe mode. When I boot into any Safe Mode, the screen halts at
"agp440.sys" and stops booting. I have to put in the 64 meg video card and
it boots back to normal.
Is there a setting or checkbox in Windows that says something like 'let
Windows manage video"?

I have built many computers but this has me stumped..

Don't want to interupt a perfectly fine thread but I thought I'd chime in
and give you a for-instance that I'd encountered once not too long ago.

MOBO in friends machine (yeah an unpaid job but IIRC they paid in beer so
all good) supported AGP 4x.
New card was 8x.
No go...
Brought it home, dug around, found a 128 MB off-brand card (don't recall
brand at the moment but could probably look it up if needed) that had
switches on it to change the multiplier. Set it to 4x, installed, worked
fine.

The question is, really, does the motherboard support AGP 8x which is likely
required/recommended for 128 MB cards? If not does is the card backwards
compatible?
