Now, it restarted automatically and show up on the apple logo screen about kernel version and something like panic(cpu 0 caller etc.) Also Debugger called:<panic> etc. Does anyone know about this situation what i can do? Thanks a lot.

Hope that helps, kernel panics often resolve with just a safe mode boot and then restart again...unless there is a physical problem such as bad memory but that usually shows up just after installing the memory, not some time later.

Three beeps at startup means there is a problem with the memory,the modules may be faulty or not seated properly.

 

1 beep-No Ram installed

2 beeps-Incompatible Ram

3 beeps-No good memory banks

4 beeps-No good images in Boot Rom

5 beeps-Processor is not useable

 

If you are comfortable working inside your MBP, take the back off and remove then reinsert the memory modules.  See it that helps.  If not, a visit to the Apple store in Nicosia would be a good idea and have the techs check it and if it is only bad memory, you can see what they will charge you to replace the memory modules.
