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!

Need help diagnosing a hardware problem

Asked by Kdo in Miscellaneous Hardware


I've got a hardware problem with a desktop system in my home office that is causing me to pull my hair out.  (Those of you that I met at the Core Conference already know that I've got precious little left to spare...)

I run Fedora on this particular box.  About a year old distribution, with most of the patches.  When I built the box, it had a one of the early versions of an AMD64 chip.  The chip was so new to the 64-bit arena that it didn't support VMWare.  The motherboard did support both SATA and EIDE, and I had a drive of each type.

Some while back an error occurred that made me believe that there was a motherboard and/or CPU issue.  I took the opportunity to buy a new MSI motherboard and dual core AMD64 chip.  I reassembled the box, and have had a series of issues since then.

The box now has sufficient I/O errors that none of the peripherals could be the source.  It must be part of the core system, but I've swapped everything and the errors have grown until the system is not bootable.

Here's where I am now.

I've replaced and/or swapped the motherboard, CPU, memory (2 1G sticks), Power Supply, 2 SATA drives, and the CD/CVD burner.

Over the weekend, I put in a new 550 watt Rosewill power supply.

The system has a NEC CD/DVD burner.  The device is fine.  When plugged into this system, the BIOS recognizes the drive, but the drive will not read a DVD, only a CD.  I pulled the drive and replaced it with another CD/DVD burner from another system -- same symptom.

The sata drive on port B is a new drive and is showing errors.  The drive that was originally on this port contained a fairly static file system.  I ran gpart on the device.  It ran for 13 hours before I stopped it.  It reported a "short read" error at random intervals every 300 to 800 sectors.  (I booted the box from a BackTrack3 distro on CD.)

The sata drive on port A has the installed O/S.  As of this past weekend, the O/S drive generates enough read errors that the O/S will not boot.


So there I am.  Having swapped all of the core system AND the mass storage peripherals, I haven't isolated the problem.  I'm sure hoping that somebody that enjoys this kind of puzzle has a really good idea.


Thanks,
Kent
