Hi , I have a serious problem with my pc .I have had it for 2.5 years and this is the first time i have a problem . My monitor crushes often in green vertical lines and after that my keyboard and mouse don't work. I restart it and the problem still exist - only in safe mode it's running. I've tried everythig i reinstall my windows and this fix the problem for a while but when i instal other software it crushes again and not only in this case - sometimes without any reason,i installed new video drivers - it does'nt help. This problem amuse me - It doesn't have any logic - if it's a hardware problem i guess it would'nt desappear for a while when i reinstall my OS. If it's a software problem reinstal of the OS will fix it permanently 
. Here is the first screenshot which i captured successfuly after reinstal and this is the lowest crush i have had (it crushes everytime in different degree)- this time i even could use the mouse and the keyboard.http://img13.imageshack.us/img13/4585/99027625.png Please give me some advices
