OS: Linux Mint 12 System: 320GB HDD, 1GB RAM, Intel Celeron 1.80GHz Last couple of weeks my PC is hanged continuously before boot. So that I have to restart my PC 2 to 5 times. It is very disgusting My point view, it may be for RAM or HDD error. Though I am not sure at all. So, anybody plz tell the way for checking HDD and RAM error (in graphical and terminal both method). Any other suggestion which is related to my PC hanging problem, is most welcome. Thanx.
