Oddly enough, no.
While even a single instance of "the bad" while loitering in the BIOS config menu proves the hardware is unreliable, if it doesn't happen at all that doesn't prove it's not the hardware. Sitting in the BIOS menu doesn't exactly ex3rcise every type of functionality provided by the hardware for use by complex software such as an OS. Hence, you can't be sure whether it didn't happen because the hardware is not faulty, or because the faulty functionality was never requested.
If the problem doesn't occur in the BIOS menu, I'd suggest testing with a completely different OS - preferably not Windows at all, so that there's no likelihood of a software overlap. Boot with a Knoppix CD or Ubuntu or another NIX build, and watch what happens.
