Possible Infection

[davikut]

Hi, my system used to restart automatically after I switched it on. I was also not able to hear sound. I formatted my computer a week ago thinking that it had been infected. I re-installed Windows and some necessary softwares.
But I'm still not able to hear sound. I checked and found that all the sound card drivers had been installed properly. I'm not sure whether there is some problem in the sound card or not.
Also after the formatting and re-install, the computer still restarts by itself at times. I've installed AVG Free 10 Antivirus in my computer and it didnt show any infection when scanned. Is my computer infected or is it some hardware problem? Here's my system's HijackThis 2.0.4 log...Thanks
