don't think it's a heat issue. had the cover off, and on, the card was never hot to the touch.
steps i did: (i had directx 8a or whatever the latest was before 9 already installed)
bios only goes up to 4x.
- removed nvidia 3X.XX drivers. uninstalled from hardware mangr.
- double checked in the remove software for any nvidia stuff, nothing. card is now running on MS drivers.
- shut down, installed new card
- installed cat 3.8 from ATI's site (OS would lock on the light blue welcome screen)
- reboot into safe mode, uninstall cats.
- installed latest VIA drivers (hyperion)
- installed directx 9.0b
- reboot, installed cats from Sapphire CD-rom, this would get me into windows, but i would have random shutdowns or lockups (monitor would turn off and no response from cpu)
- turned down bios to 2x and 64meg aperture (from 128): still getting same probs.
i'm really thinking it's a MB issue it's a few years old, which is really old via computer standards.
what i'd like to do is test it on a setup similar to mine, the MB is a KT266 north and south bridge chipset.
it's hard to remember everything i did last night, but i think i hit most of it above. It's really frustrating becuase i haven't been able to elminate anything yet. power, software, hardware, no telling what the prob is.
i would like to keep the card, i have an extra HD and scsi card i'd like to build another machine wth, but don't have the cash for a new CPU and MB. Then again, i don't want to wait until it's too late to RMA this if it's really not going to work.
