Is My Motherboard Dead? - Page 3

I think I'm just going to get the motherboard and CPU rma and sell them and invest in an I-5 2500k. Do you guys recommend a motherboard for that processor that can overclock well and is somewhat cheap?

Look at ASRock P67/Z68 or Asus P67/Z68.

  1. You pushed the VRMs too far during your stability testing attempt (this board does NOT even support the 975 as it does not support higher than 95W TDP - you should know better than to try and run a low end MSI motherboard with a high end AMD processor.  This is a 3+1 phase motherboard.  MSI were already doing everyone a pretty good favour by limiting the TDP capability to 95W - although [initial] BIOSes may not block the running as they should.  Overvolting your processor was pushing the board beyond pushing beyond its limits.  I would've expected a failure to happen immediately upon stability testing, as to begin with you would be pushing the VRM over the safe current it can handle.
  2. Your board shut down going through the first phase of a VRM failure - you may have not been through a complete failure and the PSU may have prevented that to some extent.  The second phase, if any, may have involved some more permanent and inflicting damage such as a motherboard fire
  3. Whether at first or in your attempts to restart the PC, backfired current caused damage to your PSU - rendering it unusable.  This caused additional return damage to your motherboard - plus in return the rest of your components may have been affected.  VRM failures have been known to also take down PSUs - a failure that in turn can damage other system components.
  4. When you attempted to restart the PC with a new (well, old) PSU - it was usable to the extent where the system was able to boot up.  However, damage that may have been caused by the failing of the other PSU (as with all PSU failure incidents) may have damaged other components fatally - i.e. your graphics card fan is unable to start up, your graphics card may have been killed in the incident.  The fans connected to your motherboard may have been running because of the presence of an undamaged connection to the 24-pin connector from the PSU, however the lack of a stable power current to the CPU due to a partially damaged VRM setup would nevertheless cause the setup to fail to boot anyhow.  In most cases no current would get through causing a total boot failure until the CPU power connector was removed.

In short, yes, your motherboard may have died - and the above is my best explanation of how this situation may have happened.

Your attempt to use a 125W TDP processor with overclock on a board with a low end 3+1 phase with no cooling made by a brand that is known to experience violent motherboard VRM failures across its low end AMD board lineup may have cost you multiple parts failures and multiple hundreds of dollars in damage.  While it is not common that the damage occur to this extent I have stressed that it can happen and I must unfortunately report that this may be the case for you.  This is the kind of stuff I try to warn people about and help to prevent.  Read the link in my sig: About VRMs & MOSFETs / Motherboard Safety with 125W TDP processors.  This article, which has now been up for just over a year, may be of useful resource to you as it has been to many others.  There is a long documented containing all reported failure incidents that I have found over the past year; you will find a variety of failures - some are user errors, some are due to bad motherboard design.  I have considered it important to make a difference for both.  This article may have even influenced companies such as MSI to make major design changes - which is in every way a good thing, as the problems I have pointed out can and are being addressed in several ways.  And of course, user knowledge which may not have been so high concerning VRMs (as until lately they haven't been so much an issue due to the natures of old platforms - i.e. pre-split-phase, pre 95+W TDP, pre multi cores)

Definitely only actual testing can prove any theories.  I recommend you start with the PSU because you can easily work your way from there.  Attempt to use your graphics card in another PC if you can; same with the CPU, and other components.  When the motherboard replacement from MSI comes (and I don't guarantee it will because by using an unsupported processor you may have been beyond warranty coverage), test the system quickly to see whether those other components such as the GPU and also the CPU might still work or not (if you do not have an alternate system).  Then, shut it all down, and look for a new board - because, again, this one does not actually support your processor.

10/10 For THIS!. thumb.gif
This what happened to my CPU.. I already Saw this link When i tried to unlock my Amd Athlon II x3 to to Phenom x4..

i tried to Unlock it and Run Prime95 for 1hour But it only run for 45 Min Then it Restarted/ Rebooted. turned off/standby mode.

i wait for 30min.. and i restarted it..

i knew it FAILED so. I Return it to the Stock.. Thanks for this Thread... thumb.gif
