  1. Whats the problem?
  2. Random Windows7 freezes. Have to hard reset and reboot. If a program is running with sound it will sound loop. Tried the hot fix from microsoft, updated all drivers, virus scan. This was my first self built system (about 2 months ago). Read alot about ram voltages causing freezes but I am unsure on what to set mine to.
  3. Reset the CMOS memory the right way as is described in the motherboard manual using the clear CMOS link with the power cord unplugged.
    And when the battery is out, press the power button to discharge all the electricity from the system.

  4. It could be anything, including bad PSU.
  5. OK, post your specs...

    RAM: with link please.
    HDD: /SSD
    OS type + version
  6. What version is your video driver?
  7. Thanks for the help Nikorr,

    CPU: Intel Core i7 2700k
    RAM: Kingston KHX1600C9D3K2/8GX
    Motherboard: Asrock Z77 Pro3
    GPU: EVGA GTX550Ti
    GPU Driver Version: 301.42
    WD 1TB 3.5 INT SATA 7200 BLK
    OS: Windows 7 SP1

    I have reset the CMOS, the freeze is random, so far last 1.5 hours no freezes.
  8. BTW, do you have a page file?
  9. Um, sorry for my lack of computer tech knowledge but I have windows auto selecting performance if thats what you mean. Virtual memory total paging size is 8085MB
  10. OK, did u upgrade any drivers, especially the video driver?
  11. I have updated all to the latest versions.... BIOS version 1.5, Realtek sound card, EVGA GTX550Ti nvidia drivers, Realtek network card, used intel auto update utility but no updates were found.
  12. Your BIOS is here, but I don't think its the problem.
  13. Sorry, I meant recently, when this started to happen.
  14. I believe it was happening before I upgraded my nvidia drivers. I suppose I could roll em back and see, but still havent had a freeze up since last night. So hard to say if it is fixed or not if i do make attempts to correct. Sometimes ill get 1 a day sometimes 3 in a night. Seems no rhyme or reason.
  15. Auto update utility sucks, don't use them : )

    Update the drivers from the ASRock web.

    And with graphic card driver update wait for week, to see if there are problems with that version.
  16. I ran memtest overnight a few days ago, passed everytime. I updated all available drivers from asrock website. I'll keep you informed.
  17. Cool.
  18. So froze again tonight at about 8:30 pm cst. Performed hard reset. Checked event viewer, only error/critical events were for improper shut down. *Getting rope to hang myself*
  19. Did u do a clean install when build was made?
  20. Yes, bought a copy of Windows 7 home premium. Installed on SSD drive. Upgraded firmware on SSD also.
  21. Best answer
    For the memory best use either BIOS default setting, or load an XMP Profile in the BIOS. And like Nikorr mentioned, it could be anything incl PSU. If you have another decent PSU or if you can borrow one, it is worth trying.
  22. BTW, any BSOD?
  23. Only had a bsod 1 time about 6 weeks ago. I unfortunately don't have a spare PSU. I guess I can return this one. I'll try loading the XMP. Currently it is set to auto and still freezing.
  24. Just giving an update....
    Since setting BIOS to XPM haven't had a freeze up in 2 days. Will continue to monitor a couple more days til I consider this one solved.
  25. Thx for keeping us updated.

  27. Had only 1 freeze in a week and a half since using XMP, much better than it was. I'll consider this solved. Thanks for the help everyone.
