PC Randomly Freezes When I Watch Videos/Play Games

I built a PC the middle of last year, and ever since I've been having freezing problems. Either when I'm watching a video, or playing a game at random times my PC will completely freeze, forcing me to reboot. I've checked numerous threads and tried suggestions I've found there (testing different RAM, scanning for viruses, updating the bios/video card drivers, etc.) and so far nothing has worked. Here are my specs:

Motherboard: ASUS P8Z68 DELUXE/GEN3 LGA 1155 Intel Z68
Processor: Intel Core i7-2600K Sandy Bridge 3.4GHz
Video Card: HIS Radeon HD 6970 2GB 256-bit GDDR5
PSU: Antec High Current Gamer 900W
RAM: 16GB

I also have a pretty big case (http://www.newegg.com/Product/Product.aspx?Item=N82E16811103011) with two large fans. At first I thought the card might be overheating, but even under a heavy load the highest temp it ever reached was 81 degrees (and that was only once while rendering an effects heavy video).

Any help anyone can provide would be greatly appreciated. I don't necessarily want to reinstall windows (especially since in some cases not even that worked for people), but I'll try that too if I have to.

  1. If you have run memtest ( http://www.memtest.org/ ) and the RAM is good, I would consider doing a repair installation, rather than a clean installation, since it is pretty quick and saves your programs and data (you only need to reload the Windows 7 updates). Here is a how to if you haven't done one -- I find that often works well enough to fix random issues: http://www.sevenforums.com/tutorials/3413-repair-install.html

    Thanks, I'll try that and report if it solves the freezing issue.

    You may also try running a benchmarking program for your GPU and see if it errors out during any specific sequence. Would help you to potentially isolate a possible problem.

    You can find some popular ones HERE . Where did you get your GPU temp from? If you haven't already, install GPU-Z and run a string of data collection on it and see if it spikes on there.

    I'll try that as well. ASUS included a utility with the board called AI Suite which monitors temps, and provides all kinds of system info. I usually check that and Catalyst Control for my temps.

    That's fine but everything is always better when triple confirmed. Get the temp from both AI Suite and CCC and then compare it to what GPU-Z is telling you. If they vary by I would say +/-5 degrees then you definitely have an issue there because the card isn't reporting accurately.

    Most definitely. I just listed those since you asked where I got the temps from. I'll try GPU-Z in a few and see what that says as well.
  7. Ran a benchmarking program with no issues, and my GPU temps from GPU-Z, CCC, and AI Suite are all the same. Guess it's time to try a repair install to see if that works.
  8. Ran memtest with no errors, and did a repair installation of Windows 7, but unfortunately I'm still experiencing freezes. Is there anything else I can try?
  9. I would download and install Prime95 and then startup and run it in safe mode, that will isolate most of your drivers from the stress to distinguish between a probable hardware problem and some driver incompatibility. And keep an eye on your CPU core temps during the stress.

    I assume that you are not overclocked currently since you are unstable.

    Thanks, I'll try that next. And no, I haven't even attempted to overclock due to the freezing.
  11. Ran Prime95 for about 5 hours and no errors were reported.
  12. If you would normally get a reboot in that time, then I would say all of your hardware is okay -- the problem is a driver. Although is sounds like a terrible idea, I would back up all my data and do a clean installation with only the OS drive attached (no other hdd or sdd). Check all of your bios settings to insure memory timing and controller settings (like AHCI mode) are correct just before installing after your last restart. When you start, select custom and then delete all partitions until you have one unallocated space left then let Windows install to that partition.

    Then load your chipset driver (download the latest from Intel), your LAN, and then all Windows updates. Run Prime95 until happy, then load the video driver and rerun Prime95. Then you can load all the other drivers and attach all your other disk drives, then run Prime 95 one last time before installing your programs.

    Alright, I'll try that and report back if that works.

    :wahoo: Nice spec for your computer :wahoo:

    This is what you do
    Go to command prompt > Msconfig > Start up
    All that stuffs start when you log into your computer
    You don't need nothing running from start up, Only Malware Byte {If installed}

    Ones you kill all of those processes
    You going to have to restart the computer
    Next
    Download CCleaner
    What this does remove the trash you don't need
    History, Cookies, Temp, Etc
    It will recover some of your hard drive space {Giga's}

    Next
    Download
    disk defragmenter
    You have in built into windows but it sucks and take longer


    Seen like you have Malware attacking your hard drive and causing it to freeze up
    Download
    Malware byte {Full Scan}
    You going to have to restart your computer
    Then run Malware Byte Again
    Why?
    Sometime it doesn't remove it all

    Or go to command prompt > Chkdsk /f
    Chkdsk can repair problems related to bad sectors, lost clusters, cross-linked files, and directory errors.
  15. He's done all that and more. Time for a clean install. He has had the problem since the initial build. You need to make your answer specific to the problem, not just cut and paste the same answer. :)

    Many many thanks, buddy. After multiples researches and attempts to solve this, your hint about fragmentation made me to think a little about my situation. I use to download ton of favorites series to a specific hard drive, deleting them after watching them, of course, and downloading others instead, over and over. A few months ago this problem started and only today I solved it, with the help of your advise to run a defragment tool (I used UltimateDefrag), and after the task was done, playback of HD videos (720 P series chapters) is a piece of cake. Everything came to be like once again. I wonder if the lag is due to the time and difficult for the hard disk to find the next piece of the file, written elsewhere on a cluster far from the rest containing the most part of the file playing.
