BSOD Sometimes when i work with my laptop

Your bug check and it's usual causes list memory as a problem.

Code:

STOP 0x0000003B: SYSTEM_SERVICE_EXCEPTION 
Usual causes:  System service, Device driver, graphics driver, ?memory

The following test may void the warranty of your laptop.

Take memtest. Run for 8 passes and test each stick in a know good slot for an additional 6 passes.

→ RAM - Test with Memtest86+
→ Guide to using Memtest86+ - Geeks to Go Forums

The goal is to test all the RAM sticks and all the motherboard slots.

Check your motherboard manual to ensure the RAM sticks are in the recommended motherboard slots. Some motherboards have very specific slots required for the number of RAM sticks installed.

If you get errors, stop the test and continue with the next step.

1. Remove all but one stick of RAM from your computer (this will be RAM stick #1), and run Memtest86 again, for 7 passes.
Be sure to note the RAM stick, use a piece of tape with a number, and note the motherboard slot.
If this stick passes the test then go to step #3.

2. If RAM stick #1 has errors, repeat the test with RAM stick #2 in the same motherboard slot.
If RAM stick #2 passes, this indicates that RAM stick #1 may be bad. If you want to be absolutely sure, re-test RAM stick #1 in another known good slot.
If RAM stick #2 has errors, this indicates another possible bad RAM stick, a possible motherboard slot failure or inadequate settings.
3. Test the next stick of RAM (stick #2) in the next motherboard slot.
If this RAM stick has errors repeat step #2 using a known good stick if possible, or another stick.
If this RAM stick has no errors and both sticks failed in slot#1, test RAM stick #1 in this slot.
4. If you find a stick that passes the test, test it in all the other motherboard slots.

If Part 2 testing shows errors, and all tests in Part 3 show errors, you will need to test the RAM sticks in another computer and/or test other RAM in your computer to identify the problem.

In this way, you can identify whether it is a bad stick of RAM, a bad motherboard, or incompatibility between the sticks.

At first i didn't open the laptop and i test two rams together. is this test enough or should i test rams one by one?

Umm..if you don't want to take memtest, insert one module in one slot and see how your computer performs. Do the same with all the sticks.

No. Try one by one.

Hmm, how many passes did you take for?
You need to take 8 passes max, you can leave it overnight...(while you're asleep)

Yes 8 passes. Take your time and do it, let me know the results please.

See you soon :)
