I used Spybot S & D 15 minutes ago (I've been using the software for more than a year now. I update it at least 3 times a week - FYI), I was not connected to the internet when I scanned the system, but when its already around 75% (21,+++/31,+++), my pc turned off. I didn't know why. (Does anybody experienced this?) So I turned on my pc back up and it says CMOS - error checksum. Then I chose to press F1 to proceed with the boot up process, then I used Spybot S&D again, and for the second time, it turned off. Does anybody know why? And any solution to this? I would really appreciate any help. Thanks in advance.
