One last suggestion before you give up on it. Install the PCI video
card again, then reflash the BIOS. Don't use 1007, as some people
have had trouble with that. Try to identify the current revision
of the BIOS, and get a copy of that revision to use for a reflash.
The least risky way to flash, is with a DOS boot disk, as far as
I'm concerned.
Info used during boot time, is stored in two places in the computer.
The CMOS RAM (inside the Southbridge), keeps settings recorded from
the BIOS setup screens. (Doing the "Clear CMOS" procedure, with
the computer unplugged, will clear this out.)
There is also DMI, ESCD, and microcode cache, all of which are stored
in the BIOS flash EEPROM. AFAIK, all of these bits of information
are cached from boot process to boot process. There is a remote
chance that if something in there is getting corrupted, or if
the actual boot block or main code segments in the flash EEPROM
are corrupted, that funny things will happen. (For example, say
somehow that the address of the frame buffer on the video card
is being offset - all the screen updates then won't appear on the
screen, but the computer will still be booting.)
So, try flashing the BIOS chip. In terms of the flashing process,
the flashing program will refer to two portions of the BIOS.
The boot block is one part and the rest of the device is the
other part. The boot block is what makes "Crashfree" work,
so if you don't flash the boot block, then in theory you can
recover from a bad flash of the rest of the EEPROM. I would
try a flash, without updating the boot block, to see if the
symptoms improve. If they don't improve, you could try a second
flash including updating the boot block, not that it is likely
to help.
In each case, enter the BIOS and select "Load Setup Defaults"
in the Exit menu. This will ensure that the BIOS controls
and the data structure in the CMOS RAM are aligned. After
saving the default settings, you can power down and put in
the AGP video card. (And anytime you add or remove hardware,
it is good practice to unplug the line cord, as this guarantees
that the power supply cannot source any power to the hardware.
While switching the switch on the back of the computer is
normally enough, at least one poster here had a computer keep
running, even with the switch on the back in the OFF position.)
When the computer is next powered up, the BIOS should refresh
the now blanked DMI, ESCD, microcode segments etc.
This is the last step before taking a hammer to the board
))
Or RMAing under warranty.
