Computer Freezes While Running Intensive Programs and Requires Hard Reset

I have recently upgraded by PC by replacing the motherboard to a BIOSTAR H81MG and processor to quad core i5.
I did a complete fresh install with windows 7 and installed the BIOS from the CD and graphics drivers from the NVIDIA website.

All the installs went okay and the computer was running smoothly. So I downloaded DOTA2 and jumped into a game. I maxed out my graphics settings knowing I would be able to run it. It ran really well and smooth for about 20-30 minutes then it suddenly froze. I couldnt move my mouse or Alt-Tab. Next the game gets the white overlay to say its not responding however I could still hear my Skype conversation for about 5 minutes after DOTA2 crashed. After that it went silent and froze completely, requiring a hard reset.
I thought maybe it was just DOTA2 so I installed borderlands 2 and got about 5 minutes in before the same thing happened. Next I tried Heaven 3D Benchmark again same problem.
My CPU temp while all this happens is around 40*C-50*C and my GPU temp is around 45*C--55*C

I have tried taking out RAM and running with just 1 and then using just the other stick but to no avail.

I really don't know why this is happening as I'm pretty sure everything is connected up correctly and from what I can tell all my drivers are up to date.

Does anyone have any ideas on what the problem is or how I can fix this?

Thanks in advance :D

  1. sound driver conflicts............ you can try shutting down skype. see how it goes for half hour or so.

    Hey thanks for the reply. I tried closing Skype and every other program using my sound driver and then running Borderland 2 again. Sadly it didn't work :( It still crashes after 5 mins.
  3. if you're not using the hdmi hd sound that loaded with your graphics driver/disable it or uninstall it. also check your control panel/sound and make sure what you are using for sound is fully enabled.
  4. also check windows updates for any system firmware.
  5. Or worse if you just went 'default' install on everything, then you may have alot of programs running in the background unnecessarily (liek skype) and you maxed out your 6GB (easy to do really on these new systems with a 'heavy gaming'). Use something like Auslogic Booster to clear out startup items, or even evoke Game Booster to kill off unneeded apps during gaming and see if that stablizes things.

    I realised that I hadn't updated windows 7 and so last night i installed 135 updates. Sadly this didn't help either :'(

    I was curious about this so I ran my game in windowed mode with task manager Performance tab open. I was barley even using half my usable RAM when it crashed :(
  8. specifically/what ram........... link.
    " " power supply "

    umm there both generic Kingston RAM sticks. I have one 4GB and one 2GB. I think there both 1333MHz :/
  10. again, what power supply?

    specs on ram.......... got a link?

    I said at the top but the power supply is a Right-Tech 600W and this is pretty much it http://www.web-systems.co.uk/?page=Products&pid=5808 i think... XD
  12. can't even find a link to the power supply.............. must be a real "achiever"............????

    what is the voltage printed on the ram?

    try windows updates again.......... sometime 2 and 3 passes are needed after reboot each time.

    have to think for a while.
  13. Download and run SPECCY. This can provide most specs, as well as current 'idle' temps. Also you should install MSI Afterburner and see what the temps say underload (game playing).

    Okay so for the few things next to cover, what Antivirus you use? I would download AVG / Avast! from www.filehippo.com and do a full scan, then do a fullscan with Malwarebytes just to be certain. But otherwise since you did a full clean Windows install, that leads to probably a hardware failure, which means RAM, possibly the CPU, and the GPU.

    I do know that your mixed memory is unhealthy, the systems work best with MATCHING pairs of RAM. So I would just get a 2x4GB set and plug those in (very cheap these days) and see if the problems resolve.

    I think the power supply was salvaged from another PC a few years back so I have just treated myself to a new one (Corsair Builder Series CX 750W) which should arrive on Monday.

    Both RAM sticks are 1.5V. I think i should get some new RAM a 2x4GB like Tom Tancredi suggested. Do you know anywhere cheap for the UK?

    And My windows is now fully up to date I did a couple extra restarts to be sure ;)
  15. see how the new PS goes.

    you have to check uk etailers. 1.5v or less is good.

    the restarts....... go to updates again and again.....restarting each time if prompted. some updates have patches.

    The temps i quoted in my first post are pretty much the same as the ones Speccy are giving me:
    CPU: 36*C (Idle) - 55*C (Under load)
    GPU: 23*C (Idle) - 54*C (under load)

    Is there anything else from Speccy that you think would be helpfull?

    And you're right about the RAM. Do you know anywhere cheap in the UK?
  17. the voltage is too high............ look for 1.5v or less.

    Why 1.5v? I dont know much about RAM sorry :(
  19. Think between stable power and exact same RAM chips you should be good. Also don't just look 1.5v, but also look for 'timing'. Crucial has a online scanner and can tell you all about the type of RAM you need.

    read up on the architecture of your processor.......... memory controller.
  21. Hey, I just installed my new power supply (Corsair Builder Series CX 750W) and all seems to be good :D I've all the games that were freezing before and they work fine and none have crashed yet :D
    Thanks for your help guys its been nice to speak to people who are actually nice on the internet ;)
    Thanks again :D
  22. nice?,.............. boy did you come to the wrong place....................LOL.

    glad it was a simple fix.
