This is happening because of bios upgrade but not in a bad way. May be there is a hardware problem just starting so new bios upgrade is detecting that and thats why its restarting.
basically sudden shut down occurs in either cases- Fan not working or hard disk(or RAM) gone bad.
my advise is to contact dell customer support and they will guide you thru trouble shooting steps.
they will guide you if your warranty is not there.
Testimonial: "thanks for aswering, happy new year!!"
My vostro 3500 suddently shut down quite a few times without warning. the dell helpline made me do a diagnostic check of the hard disk in which some error came up. i was told to back up my data, and then maybe format or replace the hard disk. however, after back up of data, i chose to do a defragment, and then i did the C drive error checking, which is available by right click on the C drive, thru the tools option. after this. certain bad sectors were detected and marked. after this, the laptop is working fine!! :)
