My computer will restart seemingly at random. It happens mostly while playing a game though occasionally it has happened while web browsing. It is usually preceded by a loud buzzing sound. I can chose start windows normally and it does as if nothing happened.
I have a Biostar A58MD ver 6.0 I use up to date drivers from Biostars website.
I have a Nvidia GT 610 graphics card installed
I have windows 7 service pack 1
I use the Microsoft Security Essentials and have Malwarebytes(free version) installed and run on a weekly basis
the motherboard uses Realtek Audio manager for the sound driver.
IAny help would be appreciated.
