I have a MBP (mid 2010, 13") and this is the usual kernel panic that I see each time that it restarts (sometimes it doesn't restart and it makes a continuous beeping).

What's the problem?

The first step would be to check out About Mac computer startup tones and identify which one of these startup tones is the one you're experiencing with your Mid-2010 MBP.
Please do not guess. If your startup tone does not match exactly one of the ones listed, please comment back and say so and describe which one it is closest to and what the difference is. Unfortunately, not all of the possible startup tones are listed on that page.
This is a common problem seen with MacBook Pro 13" pre-2012. It is a result of the logic board not being able to read the RAM. In this particular model it can often be caused by pressure, over time, on the bottom case thusly, causing pressure on the logic board. This issue is solved with a Logic Board replacement and in some rare cases the bottom case. To test it yourself, see if you can cause a kernel panic or freeze while applying some pressure to the center/slightly right side (from the top) of the bottom case.
To avoid this issue with these MacBook Pros do not make it a habit on using uneven surfaces (knees for example) or picking the unit up with one hand. Additionally, try not to transport it in something with other heavy objects that can apply pressure to the bottom case.
If the Mac does not freeze when applying pressure, you can test the RAM by following these steps: You could test another, less likely scenario; one RAM slot on the Mac is faulty.
If at any point the issue does not reoccur with one of the RAM sticks, use that combination of that RAM stick in the working slot only. The Mac will work fine with . only one RAM stick as long as it is > 2GB. You could also upgrade it a larger capacity RAM stick.

USE codykrieger GFXCARDSTATUS
The NvidiaCard are wrong in all of MacbookPro... :( i sucked it but i found the solve! You need to disable Nvidia and use only the Intel graphic chips!!!!
install it: https://gfx.io/ or instal the older 1.8.1 : https://github.com/codykrieger/gfx.io/find/gh-pages its better for me because it can disable full Nvidia!!!!
I suck this blackscreen freeze, and i try many thinx (ramreset, diskutil, voltage, reinstal...) and this NVIDIA DISABLE is the best....
... but some app can only use Nvidia (secondary monitor, transmission, games...) and i dont use these...
