I have put in another 1 GB RAM, now I have 2 GB. If I start Google Chrome and Thunderbird at the same time, my system freeze for up til 1 min.

That should be enough RAM.
Did you run any general performance tests: disk I/O permormance, memory speed ...
Something like:
A) sudo /sbin/hdparm -tT /dev/sda
/dev/sda: Timing cached reads: 2308 MB in 2.00 seconds = 1154.85 MB/sec Timing buffered disk reads: 276 MB in 3.00 seconds = 91.91 MB/sec
B) dstat -c --nocolor --top-bio
----total-cpu-usage---- ----most-expensive---- usr sys idl wai hiq siq| block i/o process 21 5 72 1 0 0| 36k 243B 17 4 80 0 0 0| 21 6 73 0 0 1| 35 13 53 0 0 0|kdeinit4: d 0 32k 60 15 25 0 0 0|kdeinit4: d 0 12k 28 14 59 0 0 0|kwin 0 8192B 20 7 73 0 0 0| 17 6 76 0 0 0|firefox-bin 0 24k
This will report some statistics on what application causes I/O traffic and if the system is forced to go into iowait for that.
That's a good way to track down any issues with chocking disk IO.
C) and of course: memtest
/dev/sda1: Timing cached reads: 1144 MB in 2.00 seconds = 571.46 MB/sec Timing buffered disk reads: 24 MB in 3.10 seconds = 7.75 MB/sec dstat command not found Yes, I have run the memtest.
