the other night mac pro 1,1 froze watching netflix. couldn't kill anything, had hard shut down.
when starting up, working normal, chime, gray screen, apple, progress wheel, blue screen couple seconds, , bang grey screen where, reason, mouse still works nothing else ever happens. left entire night first night, when woke next day still that.
order of events fix problem:
1. reset pram. reset logic board.
2. enter aht, won't enter goes same grey screen mouse works nothing else.
3. enter safe boot, enters safe boot fine.
4. boot snow leopard disc, goes same grey screen mouse still works.
5. wipe , reinstall snow leopard using mbp mp in target disc mode. reboot after finished installing , goes through same process before , ends @ same grey screen mouse still works.
still boots fine safe mode whatever reason, don't want run in safe mode.
reason wondering if video card because couple years ago (at end of applecare thankfully) having problems similar , replaced video card , working great again. believe card nvidia, card doesn't have fan.
looked @ graphic card , capacitors seemed fine, didn't bloated or anything, "genius" @ apple tried show me last time , couldn't tell either.
there can in safe mode diagnose further. i'd gladly buy radeon 5770 if knew fix it, i'd sure before sink $250 find out logic board dead.
help!
does have ideas? i'm new forum, if more information needed, please let me know.
tia!
