    Random computer restarts in Windows 7 64 bit


    Hello,

    Over the past few days, my desktop computer has restarted twice randomly. Both times have been during times of low demand on the computer. The first time on 7/20/12 I was browsing the internet. The second was on 7/21/12 during a time when I left the computer idle on a browser for a phone call and came back to find my computer restarted with no information about windows updates or anything that I would expect to cause an automatic restart.

    I have not run into this problem before so I checked a few things which I thought may be a problem. First I did a virus scan because I have had a few problems with infections in the past. I ran several virus programs including malwarebytes, hitmanpro 3.6.0 (trial), microsoft security essentials, and spybot. After the first restart, I found a bootkit with hitman pro (Master Boot Record (Sector 0) in C:$MBR) which was deleted successfully according to the program. I thought this was the cause of the issue.

    To be safe, I restarted and reran all the virus scans and found no further infection. I restarted another time in safe mode and ran them again and still found nothing else. However, the computer restarted today for a second time despite this infection being cleared. I reran the virus scans and found nothing again.

    Additionally, I loaded a hardware monitor program to check my computer temperatures and found them to be quite comfortable. My video card idle is running at 45C and my processor is running at 28C. I am running windows 7 64 bit which I installed from a disc on a desktop with an AMD Phenom II x6 1090T 3.20GHz processor, 8 GB RAM, and NVIDIA Geforce GTX 470 video card.

    I am not sure what other possibilities to look into or what the next step is. I have not run into this issue in the past with my computer restarting randomly and so I am worried about the issue(s) which may be present. Please let me know if I can give additional information to help or what steps I may take to alleviate this possible problem.

    In addition, I get no messages or popups when the computer restarts. It just shuts off and then comes right back on as if I had instructed it to restart.
