Try a trick of mine.

If your BIOS has a setting to set the AGP rate to 1x or 2x try that. It can help avoid motherboard replacements.

video card displays but wont play

In reply to: constant lockup/reset

sounds like the 3d chips on the graphics card aren't getting juice.
couple of ideas
1. check both auxilary power connectors
- 4pin on motherboard
- 6pin (sometimes) on back of graphics card
2. start swapping stuff
- try a less beefy graphics card,
- DRAM causes half of problems - try different slots, 1 stick only
- PSU even rosewill occasionally ships a bad one

good luck
