Hello all! I am working on a Sony VGN-NR160E laptop with windows vista home premium with service pack two.i made a new user account, and i am getting these " windows explorer has stopped working" on every couple restarts or log offs, and about a month and a half ago, i did a system recovery from the recovery dvds that i made when i bought the computer. i suspect it could be A Faulty Hard Drive or RAM. When i went into event viewer, it said that the program that crashed was "explorer.exe" and the file that caused it (i guess) was "ntdll.dll". What can i do to get rid of this problem for good??
