thanks.hmmm, could be a heat problem...
Has it been operating smoothly before it started to freeze?
Is your fans running properly (it is a silent beast, you never know)?
Or maybe its a faulty ram block? try take out the original 2GB of ram and let the new 4GB of ram stay in.
Has all of your ram blocks got the proper heatsinks attached?
thanks. i'm glad i'm not the only one. but it seems they haven't figured it out either. i do have those lines in my screen also. maybe it is the video card?hmmm, I found this thread on apples page:
well i haven't done that yet. i guess i need to do that today.well, it could be the graphic card. Have you tried to take it out and tjek for dust? When I took my card out to replace the stock cooler with a better one, I was shocked over the amount of dust it had collected.
the thing is, it's not under applecare anymore.....I had the same crashing problem. Drove me nuts.
I also had some additional symptoms, you might not have.
Replaced my video card, has run absolutely perfect since then.
Hope this helps
