The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Has this Motherboard gone Bad?

Asked by Donnie616 in Miscellaneous Hardware, Computer Motherboards, Power Supplies / UPS

I have a PC that will not boot. The CPU fan was filthy and would not spin. I cleaned it. The power-on light on the MB goes on when I plug in the PSU. But nothing else will run. No HD or DVD Rom. I removed PSU and tested it out of the case. The cpu fan still would not spin out of the case. I tried that same thing on a known good PSU and the CPU HSF spun great with the new PSU connected directly to the CPU fan.. So I found the problem. It was the PSU, correct?

Next I swapped in the known good psu, put everything back together and lo and behold, the CPU fan would not turn with the new PSU, nor would anything else work. Not even with the brandy new PSU. It turns out that testing both PSUs, even though I do not 100% trust PSU testers, they both tested good.

The question Is: CAN ANYONE OF THE EXPERTS TELL ME WHAT COMPONENT IS THE BAD ONE? (The MB power light stays on) This is a P4 Gateway 310X PC.

Thank you in advance
