The error reports generally point out to Code 41 and 6008.
In this case, the conflict was with a driver installed with AMD Catalyst.
Another user had a different kind of crash problem.
I wake up the computer it comes on-line, I login, click a web web app, etc.3.
Hibernation is actually disabled.
The solution reported was not to use Sleep or Hybrid Sleep at all.
Its better to shift to Hibernate or Shutdown instead of sleep.
If the cause due to viruses and malware is negated, then it has to be a faulty hardware.
