segfault at ip sp error 4 libxul.so. Crashes very very often

Welll... as should be... crashed while writting crash report, so ebverything was lost... Is crashing very often... sometimes few seconds between. thunderbird crashes also, but less often... lenovo s205 amd.. this machine model have a lot of problems in linux.. The question is how can i workaround .. because I cant change hardware... still thanks
