Microsoft Windows 7 Professional 64-bit 7601 Multiprocessor Free Service Pack 1
BSOD, error 0x0000004A

Our computer has crashed 5 times in the last 2 1/2 weeks, and each time the Stop error was the same error 0x0000004A. I would appreciate your help in fixing this problem - I am a 75 year-old woman with only average computer knowledge. Thanks!
