Tell me more ×  This is somewhat related to this question but at
a less serious level - one that causes frustration rather than
permanent damage.  From programs like CoreTemp and Speedfan, it
is clear that there are ways to read the critical temperature
and voltage information from a system. Is there any means of
(maliciously) writing parameters into the same monitoring
systems so that the BIOS (or whatever is responsible) could be
fooled into shutting a system down believing it was dangerously
over-voltage or over-temperature? If so, are there any viruses
known to operate this way?  I ask because I have a system (ASUS
A6U laptop) which was having problems that appeared to be either
a virus or a thermal shutdown issue. The essential problem was a
strong tendency to fail to boot into Windows XP, which usually
occurred immediately after an error reported by lsass.exe (a
frequent target of viruses). But moments later the system would
always suddenly shut down in a way suggestive of thermal issues.
Still, the sys
