Should I heat-shoot my laptop?

[Gintoki98]

Hello,
I have an laptop(MSI CX600X) that only works if I preheat it with a hair dryer, and then let it heat up in bios. If I don't preheat it with dryer, it won't even get to bios, and if I don't wait for it to heat up in bios, it just goes into hibernation, sort of same as when it doesn't get into bios or boot post, same thing.
So yeah, should I use heat gun/ bake my mobo?

Thanks in advance.

Your needing to heat it up to get it to work sounds like the heat is causing parts to expand (not shrink). This sounds like it is either the cpu/gpu not having good contact with the heatsink and heat is fixing that, or, which I think is probably more likely, a solder joint, trace, component, etc., on the motherboard is only making contact, or kicking in, after it warms up.

Try reinstalling the fan and heatsink. Make sure you use a good, but think, layer to completely cover the surface to make it can make proper contact.

If that doesn't resolve it, you may well need to replace your motherboard.

I won't ask how you figure this out.

You are not in a high humidity locale are you?

Thank you very much for your responses. I'm aware it's solder joint problem, and I've tried to clean heatsink, check fan, etc. Now it cools off even better, which is a problem itself. When the temperature gets too low, while it is operating, he just goes into that "hibernation". So I have to keep something running all the time, which slows PC. This is precisly why I want to solve that solder joint problem by baking mobo in oven(not recommended, but yeah) or using a heat gun on chip to melt solder, then press a bit, so it connects itself again. I'm not sure if this is only solution to the problem, which is why I asked the question. Which one of these two you think it's better? And yeah, I'm not from high humidity area.

The reason behind that problem is probably because I've been using it on extremly cold temperatures, such as -10 degrees Celsius and it worked. So it expanded and shrinked quite quickly, which probably made some cracks. I'm aware it needs reballing, but it's not really worthy to pay for it...

Looking forward to more opinions!

In the future I would recommend not using in such a low temp.
