New Hardware Custom build Freezes no BSOD

[Avaava]

Hey guys, I have a PC that was custom built with all new hardware, and it has hard freezes requiring a cold boot. It happens anywhere from once a month to a couple times a day
These freezes occur while doing anything from watching a movie, browsing the web, or when it's just sitting idly.

I replaced the PSU, flashed the Bios, reinstalled windows, changed the power settings, updated drivers, and re-sat the ram with no change.

Windows event viewer doesn't show anything that related to the crash except "previous system shutdown was unexpected".

After running stress, cpu, and memtest all came up fine.

Since all the hardware is new not sure what to switch out next, if I should reinstall windows 7 again or change something in the bios.


I'm using a
Intel i7 3770k,
Intel graphics 4000,
Asus H61M-A Motherboard,
1 Crucial DDR3 Ram 8GB
Samsung Evo 840 SSD as primary drive,
Seagate 1TB HDD
Corsair 550 watt PSU

Any help is appreciated.

Is all the parts intact and nothing is loose or anything?

 

[Avaava]

Thanks for the reply. I believe so, I checked for that when I switched out the PSU.

Bad ram could be the problem. I have used memtest with questionable results; bad ram wasn't detected. Try another ram chip and test results.

MemTest86+ never fails to find bad RAM if you run it long enough. Of course if you don't run it for at least eight passes results will be inconclusive, and if you run MemTest86 instead of MemTest86+ then the results are just plain questionable.

You may not have had any questionable results, but that hardly qualifies as a "never" fails.

Not in any instances I've seen. Feel free to prove me wrong, I'll happily stand corrected.

One of my own custom built systems was crashing on a random basis. I tried running MemTest86+ more than one time on it and there was no problem. After replacing the PSU and checking all connections, I decided to remove one of the 4 meg chips and "voila" all was good. Now, let's see, how can I prove that to you?

Anyway, "never" is "always" an overstatement.

 

[Boozad]

You ran it for more than eight passes? Did you swap the sticks over to prove it wasn't the RAM slots?

Not really, I never eat sushi. That's an understatement.

 

[Laith]

Good comeback, Boozad.

 

[Avaava]

I ran it 5 times with all passes, I can run it again. I didn't switch out the stick yet, I don't have another one to switch it with. Thanks

 

[Boozad]

Five times? You mean five passes?

 

[Avaava]

yeah, 5 passes

 

[Boozad]

You need to run at least 8 passes for conclusive results.

Download and run MemTest86+ to test your RAM. http://www.sevenforums.com/tutorials/105647-ram-test-memtest86.html

   Note

Run MemTest86+ for at least 8 passes. Ideally set it off before you go to bed and leave it overnight, we're looking for zero errors here. A single error will show something's going bad with your RAM.

 

[Avaava]

Ok, will do.
