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.

Which is faulty: Motherboard or CPU?

Asked by soapergem in Computer Motherboards, Computer CPU Processors, Computer Memory (RAM)

Tags: faulty, motherboard, cpu

I recently decided, after 4 years, that it was time to upgrade my PC. So I bought a number of new hardware items, including a new CPU, a new motherboard, and new RAM (2 sticks).

I ordered most of those from Newegg, and the RAM from Crucial. I went to install it all, and much to my dismay, nothing really worked right. So being the A+ certified tech I am, I ran MemTest+ right away and found about 30,000 errors before the test stopped completely and shut down the computer. "Okay, so the RAM is bad," I thought. So I sent the RAM back to Crucial, and they sent me another 2 new sticks, which just arrived yesterday.

I went to install them and still ran into many of the same problems. I thought it was awfully strange that 4 different sticks of brand new RAM would all have the same problem, so I went over to a friend's house, installed the RAM on his computer and re-ran MemTest+. No errors. None at all. Okay, so the RAM's not bad.

So then I stripped my system down bare, so that the only components connected were: CPU, Heatsink/fan, Motherboard, RAM, 1 × DVD drive, 1 × Hard Drive, and Power Supply. I unplugged everything else, including the graphics card, opting to use only the onboard graphics. This ensured that as few devices as possible were drawing power from the power supply. I re-ran MemTest+, and still came up with all the same errors.

So now what I'm thinking is this:either the CPU or the motherboard is at fault. However, I'm not sure how to definitively tell which one is faulty. I can see that MemTest+ fails consistently no matter what RAM I put in there, but I'm wondering if anyone else has come across any similar situations, and if so, what does this mean? Do I remove the CPU from the motherboard and send one (or both) of them back? Thanks.

Here are the full details on the hardware I ordered:

* CPU: AMD Athlon 64 6000+ (Socket AM2)
* Motherboard: Giga-Byte GA-M61P-S3
* RAM: 2 × 2.0GB 240-pin DDR2 PC2-5300 DIMM (Product #CT2KIT25664AA667)
