I can think of two reason this may happen.
1. You're object is really large or really small. Try merging your model into a fresh scene and see how it compares to the default perspective viewport grid.
2. Try resetting the xforms of the model.
3. Finally, maybe your video card isn't supported.
My object is somewhat decent size, and it was all fine before yesterday ( worked on the file for a couple of days now ). So it's not the size. I always reset xforms and such when mirroring and stuff. And my video card is a 460mx and it was working fine for almost a year now.
I think you're right, I will import the object into a new scene and see what happens.
Update: Importing to new scene did not work, nor did reseting all xforms. I know it is definitely not the video card, as my other scenes are working just fine and have no problems with the wiring. :/
