I have an acer 7720 laptop which I've been running happily for a couple of years with Vista32 preinstalled. Recently I decided to install windows 7 (32) ultimate. I didn't scrub my HD when I did this, my old vista windows folder is still kept as a backup in my drive.
The Windows 7 installation went fine, however now I occasionally get a crash - about once every 7 hours or so and it seems to happen quite randomly (not related to a specific task). Not even a BSOD; the laptop just powers off instantly. Running my windows 7 troubleshooter it suggested updated my BIOS.
My question is this; is this problem likely to be anything to do with BIOS? Afaik the bios has nothing to do with the OS. I can go ahead and reflash my bios to the latest version but I'm reluctant to do this unless I know it's the problem (scared of bricking my laptop).
Thanks in advance
