Re: Help needed!!
Some simple things to consider reside in the system BIOS setup software.
- Disable AGP fast writes, which can make many chipsets behave poorly.
- Some BIOS "turbo" settings may cause problems in some situations. Look for any on screen notes regarding "may cause insability" wrt AGP port.
- Try loading BIOS setup defaults or, on many setup programs, the "failsafe" defaults. Beware that loading defaults will cause you to have to locate any settings that may need to be a certain way (for example, enabling extra onboard IDE hardware). I find the defaults to be aggressive, so they should serve as a last-resort attempt at fixing your problem.
Other things to look for are:
Up-to-date AGP miniport driver, supplied with the chipset's driver set.
Up-to-date NVIDIA display driver
Try using dxdiag to try to pinpoint the problem further
