Hello Aries and everyone ,
I can only recommend that if anybody has computer problems, join the following forum
http://www.techsupportforum.com/
The free registration is easy and assistance is also free. The experts will guide you through step by step to solve your problem. I've seen them fix some real humdingers. I don't consider myself a greenhorn in the computer department but I am forever learning from these guys and gathering useful information. The site also has many neat diagnosis tools for checking out such hardware as mainboard, cpu etc and even the varying system voltages.
