Random crashes, no BSOD

I built my first computer this year and for as long as I've had it, the thing's been crashing randomly with no BSOD. There will be the occasional 'proper' crash, but I'm not worried about those right now.
For the past few months, I've been looking around the internet for solutions, but nothing has worked. I recently upgraded from a 550w PSU to a 650w PSU thinking that I was having power problems, but I'm still getting the nasty crashes.

The crashes will happen nearly any time of the day and have happen nearly every day, but don't occur until I've had the computer on for at least an hour. They mostly happen near the end of the day. The crashes have no BSOD and mixed results from the dumps: either a corrupt dump, a system error, or an ntkrnlmp.exe error.
There will often be one to two more crashes a couple minutes after the first one. To avoid this, I often press the reset button while the computer is booting up. I don't know if this is bad for the computer, but it stops the crashes for a while.

STATS:
CPU: Phenom II X4 965 3.4GHz
GPU: Sapphire Radeon HD 7850 1GB
RAM: G.SKILL 16GB DDR3
Motherboard: ASUS M5A97 LE R2.0 AM3+
PSU: Rosewill Capstone 650W
HDD: Seagate Barracuda ST1000DM003 1TB 7200RPM
OS: Windows 8 64-bit

This is the first computer that I've ever had problems with (as I said, first self-built) so I'm not good with troubleshooting or minidumps, although I can look things up if I have too.

  1. Random new build crashes are often due to bad RAM. Download memtest and run it at least overnight and really for at least 12 hours to test all of your 16GB. Any errors at all mean a problem.

    http://www.memtest.org/

    If you need help running memtest post back here.
  2. I ran memtest overnight and it said 'Pass complete, no errors'.
    How many passes was I supposed to do?
  3. I forget how many passes = how many hours. Did you run it at least 12hours?
  4. No, I ran it for 10.5 hrs. :/ The pass it was running was at about 40%.
  5. Do you have 4 x 4GB sticks or 2 x 8Gb sticks?

    Really to fully test 16GB you probably need to run memtest close to 24 hours. Or 5 or 6 passes. Still there are no big problems if there were no errors in 10 and a half hours.
  6. I have 4 x 4GB sticks.

    If there were no problems, what do you suggest I do?
  7. My internet is up and down randomly right now and it will be Tuesday before they can get a tech out here so if I don't reply back I have not forgotten about you.

    My advice is to try with 2 sticks of RAM right now. You will not lose any performance and 16GB can be hard on some systems. You may need to slightly bump the RAM voltage with 4 sticks so lets see if it crashes with 2 sticks.

    It my not even be RAM but that is such a common cause I want to rule it out before moving on.
  8. I've run my computer with two sticks of RAM since Saturday and there have been no crashes; I think that was the problem.

    Put the 2 other sticks in and enable XMP in BIOS. Then manually up the DRAM voltage to 1.55v. That may fix it.

    XMP may not be an option since that is an AMD build. If not manually configure the timings and speed to what the sticks are listed at then bump the voltage by .05v.
  10. I didn't see anything labled 'XMP' in the BIOS, so I searched around and found this. I followed the guy's instructions and set the overclock tuner to D.O.C.P.

    Just so you know, the DRAM voltage was already set to 1.65v, so I had to down it instead of up it.
  11. What is your memory rated at? 1.65v or 1.5v? If it's 1.65v RAM it will need to be set to 1.65v. If it's a 1.5v kit and your board is setting it to 1.65v that could be the problem.
  12. My memory is rated at 1.5v. If I changed the DRAM voltage manually, shouldn't that fix the problem? Or would the voltage reste itself?
  13. You should be able to manually set it. I would try it at 1.5v and see if you still have crashes. If so take it to 1.55v. 1.65v may very well be too much for the modules and what's causing your crashes.

    Just make sure you 'save and exit' in BIOS.
  14. I've been running my computer using your advice for the past five days and there haven't been any crashes. :) I think the RAM voltage was the problem. Thanks!
  15. Glad to help! :)
