Issue occurred again. This I didn't tried to do anything but was trying to shutdown the laptop. The screen shows as Shutting down but after 15-20 mins, laptop crashes and reboots. I checked the event log for errors and noticed the event after every crash.
"The computer has rebooted from a bugcheck. The bugcheck was: 0x0000009f (0x0000000000000004, 0x0000000000000258, 0xfffffa80033d2b50, 0xfffff800055823d0). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 032313-18345-01."
"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."
Same error on 10/03/2013 as well
Multiple events logged --"The driver
detected a controller error on \Device\CdRom0."
