One option to look at is which video card you're using. For example, on mine, the integrated (Intel) video has gone out, and the computer is prone to system halts. If I have it on an external monitor, works fine. I currently have a utility, gfxCardStatus, to force it to use the higher performance card.

In that kind of cases, the Logic board seems faulty.

It is strange but the mac runs fine on windows...
