When I thought the problem was overheating, before repasting, I had tried Left 4 Dead 2, on the highest graphical settings it did blackscreen, but on minimum it didn't.

I have the G73-A2 I think, I didn't add or change any of the memory sticks, meaning I have 8gb. Could the problem really be caused by a faulty memory stick? I'd rather not have to remove any since I have no idea how to and afraid to break something, but if it's a real possibility then I guess I'll have no other choice.

A quick update, I arrived from work today and the screen now is blank independent of what is running. Restarting and/or closing and opening the lid seemingly has no effect. I'm going to attempt removing memory sticks as suggested, will report again hopefully after I'm done.

Edit: I have four 2gb sticks, since the 4th is of hard access (Requires almost a full disassemble), I decided to leave it on to try out. With only the 4th stick plugged in, computer would not start.

I then added another stick, totaling 4gb of RAM. Computer would start, main monitor would start but in less than 5 seconds go blank, while the external monitor would still function properly. Tried replacing the memory stick with the other 2 available, but got the same results.

I'm convinced that, if the problem is a faulty memory, the 4th untouched stick is the problem. But then again, I start to doubt that is the issue, since I believe a memory problem would affect all display, instead of just the inbuilt monitor, since my external monitor is functioning properly.

I am planning on disassembling the notebook again tomorrow in the morning, to replace the 4th memory stick.

I am open to any suggestions, and thanks in advance.

I'll be checking the cables soon, but one thing that really doesn't make sense to me is that the screen only goes out in a game, but returns shortly after I close it. If anyone could explain the logic behind it, I'd really appreciate it.

Also, how could I check if it is actually a defective laptop display?

I'm sorry, I wasn't clear. At one point, the original symptom had changed to an always blank screen, but later it returned to the original state, where it works fine until playing a game.

Said games do not change the display resolution, since they are being played windowed, and even tabbing out of it for a short period sometimes may make the monitor flicker back to normal. Tabbing into the game again almost instantly causes it to go black.

There's a post above the one I quoted, but it's cut off from me, so that's all the info I can give on the matter so far.
