Martin, it sounds like your Display Adapter driver is no longer being
properly recognised, is incorrectly set-up, or is corrupted. You need to
start again.

Boot into *Safe Mode* and in Device Manager, 'Remove' any/all Display
Adapters and Monitors and then re-boot. WinMe *should* re-detect (Plug&Play)
your video card and monitor and then should install the 'correct' drivers.

Be sure you have the latest WinMe driver for your Video Card (Adapter) which
you should be available to download from the card manufacturers web site if
necessary.

HTH and good luck

Hello all.

My nephews have a Compaq Deskpro 4000.
Upgraded with various bits - it's got a Pentium 233MMX, 112MBs RAM and a
Voodoo 3 2000 video card.
(USB2 PCI card, bog-standard PCI sound card and bluetooth dongle too
BTW!).

I recently had the pc to fix - discovering a total of fourteen trojans, of
which three or four had already infected the system!

I successfully backed up all data to my Windows XP Pro pc and deleted the
various sources of the trojans - all dodgy archives of NGage games they'd
downloaded from P2P sharing. I used The Cleaner and KasperskyAV to clean
up everything.
Deleted all partitions on both the Compaq's hard drives.
And successfully got Windows ME freshly installed and updated with all the
latest updates.

All working 100% - scanned and clean too!

So i returned the pc to them yesterday.
We booted it up and it detected my nephews' monitor and installed it - i'd
re-installed the system using an old spare monitor i have lying around.
All working ok except we were stuck in 640 x 480 resolution.
We could choose 640 x 480 in either 256 colours, 16 bit clour or (i forget
it's highest setting but think it was 24 bit colour).
However we couldn't get any resolution other than 640 x 480.

Previously, with the same monitor and also with the old monitor used to
re-install the system, we had

640 x 480
800 x 600
1024 x 768

And all three of these resolutions were available in three different
colour depths.

Nothing has changed - after the reinstall of Windows ME i installed the
last updated version of the Voodoo drivers.
These were the same drivers that i'd previously installed on the Compaq
when it was working in all three resolutions.
DirectX is updated to the latest version and that's the same as was on the
old installation of Windows ME.
No driver or software changes have occurred.

So i've been through endless iterations of driver and monitor installs and
uninstalls but haven't been able to restore the pc to it's three different
video resolutions.
Also been though the Windows\Inf folder and deleted a couple of Voodoo
.INF files before one of the driver installs but it didn't help.
Changed drivers through Device Manager and the Display properties Advanced
setting too.

I've left the pc, up and working, with them but really want to get the
three avaliable resolutions to be available - 640 x 480 is workable but
hardly adequate.

Can anyone help?

Thanks.

Martin.
