Random Computer Freezes with no BSOD
I build a new computer about a month ago and have had an issue with the computer freezing often (only twice have I gotten a BSOD, the rest of the over 50 times the computer just freezes). By freezing, I mean that the fans on the computer still
run like normal, but the screen is frozen and the mouse and keyboard do not respond (cannot get cap lock or num lock keys to change the corresponding keyboard lights). Holding down the power button on the case shuts the computer down and hitting
the reset button on the case and the computer reboots (and offers the option to boot into safe mode). The freezes happen seemingly randomly. They can happen during surfing the web or just when the computer is idle and I'll come back and it's frozen.
Sometimes I can only boot up and surf the net for 30 seconds before a freeze. Other times I can run for almost a week while running Photoshop Extended and games such as Metro 2033 in 1920x1080 with very high settings and AA enabled.
My CPU is never stressed when the freezes happen and the tempuratures are always fine when the freezes happen (almost always less than 40-deg C). The freezes also happen in Safe Mode (both networking and non-networking). My motherboard BIOS and
all drivers are fully up to date. I have read that these types of freezes are generally hardware related since I almost never get a BSOD, but the only hardware check I know how to do is the memory.
I cannot even get through 1 pass of MemCheck86 without it freezing but I never get any error messages prior to the MemCheck86 freeze. The MemCheck86 test also freezes at seemingly random times.(I am running MemCheck off an .iso burned to a DVD). I
have been running MemCheck86 with all 3 of my 2GB sticks installed and the freezes are not isolated to any section of the memory being tested.
I have not done any tweaking or overclocking to the system and the memory manufacturer confirms that my memory is compatible with my motherboard.
I have gotten two BSODs since I've build the computer, but I was not the one using the computer at the time, so I was unable to see the error message, but I can share the .dmp files if someone out there knows how to read them (I tried with the debug program
but failed). I have read other similar posts, but there does not seem to be a situation that really matches mine exactly. There are a lot of similarities, but then there is usually one big detail that is different (their computers don't freeze
in safe mode...mine does, etc) Hopefully someout out there can give some insight into what is wrong or at least the next troubleshooting tip. I'll see if I can figure out how to share the .dmp files.
My computer's specs:
Windows 7 64-bit Professional fully patched
Core i7 950 with Noctua NH-D14 cooler
Asus P6X58D-E motherboard
NVidia GTX460 from EVGA
3x 2GB DDR3 PC3-10600 memory from Crucial
1000 GB Samsung Spinpoint Harddrive (7200 RPM)
Lite-On DVD burner
Corsair 650TX power supply plugged into a surge protector

Update the BIOS, try to disable the TurboBoost function."A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

Thanks for the quick reply! The latest BIOS for my motherboard came out months prior to my purchase, and I have been running the latest version since initial boot.
I will try disabling TurboBoost when I get a chance and report back. Does this mean I have a bad processor and need to get it replaced?
October 27th, 2010 12:16pm
I disabled TurboBoost in the Bios and started up the computer and the same freeze happened.
Also an update: After I got the freeze I went back to the Bios to re-enable TurboBoost and the computer froze while I was inside the Bios before I could make any changes.
It seems as though my processor is bad, but I've heard that's almost unheard of. Is there any other possible explanation? Are there any tests that I can run to show as proof if I try to return the processor under warranty to Intel?

It may also be your motherboard. What is the CPU temperature?"A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

Nothing over 40-deg C even with hyper-threading enabled

Do you have more than one memory module? If so, try running with just one. If that doesn't work, pull the memory module and run with another one. Also, if you have a fan on your video card, make sure it is spinning.

Run a Stresstest tool like Prime95 and check your CPU for stability issues."A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

Thanks for the tips! I'll check my video card fan, try the one memory module at a time and I'll also try the Prime95 test when I get a chance later today. I'll report back what I find.

Maybe you should try to down-grade your bios. Also you should go to Best-Buy and Buy an open-box Motherboard compatible with you CPU, then see if the computer freezes. I understand is a lot of work but you want to find out the error. If the new motherboard has no problems then you should either keep
it, and return the original or, get another motherboard. You can also buy some RAM to test it out.
In these circumstances you can only try to see which is the faulty component. Sometime there is a bad implementation which cannot corrected. I hope yours is not the case. Good LUCK!

Thanks for everyone's input! I'm learning a lot through this process. Latest update: I checked the fan on my video card and it was running fine, so I started running MemCheck86 with only single memory sticks installed. One of the
sticks consistently froze, while the other two were able to make it through multiple passes without error. So it appears that I have a bad memory stick, but I'm not convinced that the memory stick is my only problem given the above information in my
dump file.
I'll still run the Prime95 (in dual-channel memory mode) and report back any issues I find just for completeness of information in case others want to follow and learn from this thread.
October 28th, 2010 8:40pm
OK, ran the Prime95 Large FFTs test for 4 hours (I'll run a longer one tonight) and topped out at 53-deg C with no problems. Ambient temp of 24-deg C. It looks like that one stick of Ram was my problem. Thanks everyone for their
help!
