Exasperating: the issues of a mbp (l '08) | fan control vs display i.a.

Question

I'm going to go crazy over this. My MBP (Late 2008) is producing one issue after another and they start to heap. Gradually, I don't know where I'm off anymore. The supportline, naturally, doesn't have a clue either and my good old buddy has already been in repair about a month ago, when they changed the logic board.
For once, the fans spin almost insanely at a speed of 6208 rpm, what makes the MBP not really a treat for the ears and the battery is most likely affected, too. That can neither be healthy nor be correct. Most of the times, what I can't clearly understand, it helps to hold the device at a slant for about half a minute. Then it calms down, what doesn't last for long if at all.
On the other hand, the MBP says good bye about five times a day (sometimes more, sometimes less and, above all, without any apparent reason), as it just goes into the standby mode and, straightly following, without an input, awakes again.
By the way, the loudspeakers crunch and crack latterly, as soon as you "turn" the music a little tiny bit louder and, also, the green LED goes out all the time but only at full load. This, being seen relatively, bothers me the least. Now and then it likes to hang itself up, too, when it does not react at any input at all. Then it's time to take off the power supply.
I just don't comprehend a thing. What would you recommend? Maybe anyone with the same deplorable story here? Within that price category, I got to say, I am expecting something else. However, it has been a great experience up to now and I don't want to miss out on such a great product, which it absolutely is - as long as it works the way it should.
In hope and with greetings,
sorry for my bad English,
Daniel

Answer 1

The problem is that I'm kind of reliant on my MBP for school and, as I've experienced it before, it usually takes about two weeks to get it back.
Could it be that, at least in case of the issue about the sudden standby, a RAM module is the cause? I opine that it mostly happens when the RAM is almost written on to a point where it is virtually full.
Any ideas, guys?
