Ok, so my computer crashed the other night and I went through a sereis or steps to isolate the issue (including new PSU) and now its down to CPU or mobo. One of the two are obviously faulty.
From the link within that link, it seems that your mobo is about 2 years old, You bought that from newegg in 2007. I am not computer expert but my computer was doing the same thing. It seems at the end that my mobo was too weak (or had some hardware support issues) and was kind of short circuiting. I dumped the whole computer and bought a brandname desktop from an electronic store.
