MBP mid 2010, new logicboard - still video problems?

[Ritte]

Hi, I've a macbook pro mid 2010 that have had videoproblems as described here:
http://support.apple.com/kb/TS4088

My computer restarted and displayed a kernel panic-message.
I went to my local apple store and they changed the logic board without cost covered by the program.

I've now used my mbp with the new logic board 4 days and I've experienced a black screen and a restart is needed for the mbp to work again. Latest time I was gone 10 min from my computer and the display was set to rest.

My question is, is it possible that I still have the problems described in the program even when I've a new logic board?

To answer your answer, yes.

could be bad ram too. Run a ram test.

The genius at AS did some test, I suspect that he checked the RAM to.
They can't miss a bad ram can they?

Try running this: http://osxdaily.com/2011/05/03/memtest-mac-ram-test/ or another option: http://www.macupdate.com/app/mac/15837/rember

or another equivalent.

Bad RAM doesn't always show up until you run tests a lot.

I did a memtest, the extended one, It took all night and my computer passed the test. Is it enough to do it one time or should I do it several times?

Probably just a DOA board - it does happen.

If it passed, then your ram is probably ok. Bad ram can cause crashes though, so it was good to run the test to eliminate that possibility.
