ATI Radeon Crashes in XP

[Warren]

My WinXP computer is crashing with either a black screen or vertical
bars on the screen. I have a ATI Radeon 64 VIVO AGP in an Epox 8k7a+
with athlon 1.33. Everything was working together fine and then the
computer started crashing randomly with vertical bars. Now I can't
get to OS to even boot up even in the safe (crashes at amdagpxp.sys)or
VGA mode. I have to change to an old PCI video card to get into the
system. ATI send me a new Video card even though they found nothing
wrong with the old one. I've loaded the latest AGP miniport drivers
for my motherboard and lowered the AGP speed in the bios to 2x from
4x. A fresh install of XP or upgrade to SP1 still crashes.
I hope someone has an idea on what to do as I'm stumped and very
frustrated.

Set your BIOS to default configuration.

You might want to try rolling back your AGP driver for your chipset.. I
assume because the the mobo you mentioned uses a hybrid chipset with a
combination of an AMD northbridge and an VIA Soutbridge maybe something got
screwed up...

Roll back your drivers or uninstall all your agp chipset drivers, reset your
bios config, and try the newest WHQL vid card drivers for the card you are
using...

Also check some of the specific AMD reg fixes for AGP speed, and other
settings that can often adversely affect stability and performance...

People will often suspect a weak or dirty powersupply, but I have my system
running on a Powerman 235W ATX unit and I never crash...

- ECS K7VTA rev 3.1
- Athlon XP 1800+
- 512Mb PC333 DDR
- ATI 8500 64Mb DDR @ 290/290
- ATI TV Wonder PCI
- SB Live Value
- 3com 3c905 + Onboard Realtek 8139 Nic's
- 2 x 80Gb Seagate 7200rpm HD's in RAID 0 on integrated Promise RAID
controller
- LG 24x10x40 CDRW + Toshiba 6x DVD-ROM

So its not a powerhouse by anymeans and isn't overclocked save the vid
card.. But it is a lot more system than is supposed to be stable on a 235W

Uninstalled the old ati drivers and restored the bios to the optimal
configuration and it works. Can't figure out how the bios setting
changed to cause the problem to begin with. Thanks for the help.
Disappointing that ati need to give me a 5 page email which was hard
to follow. Your solution was better. Thanks
