Indeed this is a nice program (AWC) but it doesn't help with hardware errors...I'm curious to know which program Marcel uses for these kind of errors.
A colleague told me this week he used Fresh Diagnose (7.82) It has a nice interface and includes some benchmarks (Freeware) (Don't use the Dutch interface: really bad translations unless you understand: "middelen van de hardware")
Of course software can fix only a very limited part of hardware errors, they don't install a mini pc technician in your pc... too bad though.
Edit: Tried the Freshdiagnostic tool myself now and as the title says, it's just a diagnostic tool. On my pc I had to end it through taskmanager, it didn't respond on normal exit functions
