Weird screen at startup

Hello,

My recent macbook pro (mi-2012) is going very hot (104°C) on basic tasks (chrome, multitask ...). I went in an apple store, and they didn't found any problem. So apparently, my processor is going very hot (the processor already went to 105°C and the maximum temperature of my processor recommended by intel is 105°C ...), and it seems to be normal.

Since some weeks, my computer shows a weird screen when I wake it up, or when I start it up. At the begining, the screen appeared less than a second, but now, it appear sometimes more than 3 seconds. Have you already seen that kind of screen ? May the high temperature cause this garbage on the screen ?

Thanks, and sorry my bad english,

Try Reset PRAM.

Some of the display settings are stored in PRAM.

Try these two steps.

Reset SMC. http://support.apple.com/kb/HT3964

Choose the appropriate method.

"Resetting SMC on portables with a battery you should not remove on your own".

Start up in Safe Mode.

If this does not help, you may have to take the computer to the Apple store to have it checked out. Diagnosis is free of charge.

I tried to reset the SMC, but the weird screen appears randomly, so I can't test with safe mode (generally, the screen appears after some hours of standby, and stays 1s to 3s). I left my computer to the Apple Store few days ago for my heat problem, they made software and hardware tests but they told me that they didn't found any problem. Do you think I should go back to the apple store ?

Sorry to insist so much, but I would like to know if there is a real danger for my computer with this screen ... And if there is one, I would like to use this discussion to show to Apple Store that there is a real problem. It read that it could be a sign of a dying memory, what do you think of it ?
