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!

My PC powers on but will not boot up and has no display

Asked by spamsoft in General Computer Systems

Tags: pc, powers, boot, up

On pressing the power on button, all the fans operate (case/ chasis and cpu), in addition all the relevant lights blink, dvd lights/ power on light etc. Therefore it appears that there is power running through the motherboard. However, the first time  I do this it goes through the boot process, tests the RAM successfully etc and reaches the hardware summary screen. Just as windows XP is about to start the blue screen of death appears reading various messages from memory to hard drive errors on different occassions when I power up the PC.  However on subsequent occassions, when I power up again or press the reset after the blue screen, it simply shows no display, it does not even beep, the hard disks do not turn on. I have replaced both the motherboard and the graphics card and it is still no better. As the RAM is testing ok when it does test it and this should not prevent the PC not booting up even if it were faulty then it seems to suggest either a CPU or PSU failure. It is also significant to mention that there has recently been a very large storm in my area which caused a modem on my other PC to burn out. In addition, I have not been using any surge protection hardware. Can someone please help me diagnose this confusing problem.
