|1. We respond to these forums for free in our own spare time, purely to try and help others. Referring to our advice as crap is not the way to get assistance.|
2. "You" are the one who is fixing the machine - we can only advise.
3. Some problems can only be properly diagnosed by someone looking at the computer and carying out tests. May I suggest that you find a suitable repair shop and do just that.
If it were mine I would try a Live Linux CD (such as Puppy Linux). If that didn't work either, then it would at least prove it was a hardware fault. If Puppy works then you would need to look into Windows further, with or without our advice.
