Hello,

My Problem
I am start getting BSOD since last week. It happen randomly, where ever may be, in Safe Mode, Bootup screen, dekstop idle, playing games. The STOP message I get is MACHINE_CHECK_EXCEPTION - BugCheck 9C, {4, 805461f0, b2000000, 70f0f}.

What I have tried
  • I have 2 * 512MB RAM. I had try to take out 1 of them and test, but BSOD still happen no matter which RAM i plug in, no matter which slot i used.
  • I plug out my DVD drive. So now it left CPU, PSU, mobo, Graphic card, RAM and HDD running.
  • At beginning I thought is driver / s/w problem. So I uninstall nvidia IDE driver, run chkdsk, scan C drive with kapersky anti virus.
  • Lastly, I narrow down my problem and I confident that the problem is on h/w. I open my side panel and blow with Fan and play game. While it is blow with Fan, no BSOD happen. Then I switch off my fan for awhile, BSOD happen again.
  • I monitor the temperature using Everest Free Edition and the temperature for HDD, CPU and graphic card are at normal temperature, did not show that overheat.
My Question
I need to narrow down which part of my h/w is overheating or fault. May anyone help me or guide me? Thanks in advanced.

ps:I have attach my miniDump result that debug using WInDbg. Sorry for poor grammar. If need any details that I miss out please tell me.

Rick

You could try monitoring your system temps with SpeedFan.

This error appears to be generated by your CPU (rather than Windows). Although it's most likely that the CPU is involved with this error, it's by no means certain. Most often this error occurs due to overheating (which is your situation)

A couple of questions:
1) Are you overclocking? If so, stop it until you have finished troubleshooting this error. If the error stops when you stop overclocking, then the cause is overclocking the system beyond it's abilities.
2) Monitor the temperatures without the fan blowing on the system from the outside - and then play the game. You should be able to notice a rise in temperature before the BSOD occurs. Which component is overheating?
3) You may want to ensure that you've got a good thin coating of thermal grease between the CPU and CPU Cooler (and that the CPU fan is operating.
4) Check all the fans in your system to be sure that they are operating (including any video card fan that may be present)
5) Ensure that the fins in all the coolers are cleaned out (sometimes dust remains inside them even when cleaning the outside of the cooler).

Let us know what happens and we can move on from there.

Not sure what method you used to remove dust...but it won't hurt to reseat memory and check all connections before attempting reboot.

OTOH, I've not proceeded with anything when I realized I had a known overheating issue on a system...until it was corrected.

I suspect My mobo is dead. :thumbsup: :trumpet:
When I start my power button. No beep sound, all fan running, mobo (msi) fan slowly running/ stop running, monitor black screen.
Thanks everyone here for helping me. But I just screw up my pc more seriously. :flowers:
