Random Freezing on Win7 64 bit

I experience random freezing on my pc. It just freeze with no error message or blue screen. It happens even if I am just browsing, watching videos, typing or gaming. I am not sure which causes this since it does not show any error message. It is so random and I am not sure what triggers it.

Things I have tried:
+antivirus checking
+malware checking
+memtest for 24 hours all passed
+memtest with 1 stick each
+updated gpu drivers

SPECS:
windows 7 64 bit
i3 3220
P8B75-M LE - Motherboard
gts 450
1 ssd INTEL SSDSC2CT060A3
2 storage devices WD
8 gig ram Vengeance® Low Profile — 8GB Dual Channel DDR3 Memory Kit (CML8GX3M2A1600C9)

i checked the QVL for my memory and i did not find it there. could this be a possible issue?
i also did not update my bios. it is the stock bios from the day i purchased it.

any help or suggestion will be greatly appreciated. tnx ;)

  1. UPDATE 8/01:
    i changed the memory timings but didn't make any changes. there was still episodes of freezing.
    hci memtest and memtest+ were all good for 24 hours testing
    drivers for vc also updated

    NEW THEORY:
    i googled about random freezing on SSDs and found out that its a possibility. i am using intel 330 ssd 60 gig. i am not sure if my settings were correct but so far its working (but not really due to freezing). i upgraded my drivers and my intel tool box detects my ssd as good. so i am not sure what other settings I should be adjusting on my bios. any ideas? tnx

    UPDATE 8/3:
    Little progress. It no longer freezes and I reboot it. It still freezes and but I can move it after 4-5 seconds and my mouse cursor becomes blurry (WTF??) I will try to either get a new SSD or get a new PSU?? Which is which?
  2. Well my computer also freezes randomly. My fix was to misdirect the BIOS. What I did was:
    1. entered BIOS on boot up and instructed it to boot from a USB drive and not the HHD - I made that misdirection in two places.
    2. when the computer boots it now says "no operating system found - press CTRL-ALT-DEL"
    3. the next thing to do is manually direct the boot up to the hard drive. Your machine may require "Press F9" or "Press F12".
    4. I direct boot up to the proper HHD and I have not had a freeze since.

    Don't know why it works for me, but it does. Ron.
  3. I've been there with one of my PCs. I spent a light year's worth of effort with no results. I'd recommend a software reinstall followed by driver update. This won't guarantee a fix though.

    I have tried doing this more than once with no success. Now I ditched my SSD and so far the problem is gone. But it does show up from time to time but not as frequent when having the SSD. So I will try to get a new board and psu. That might be causing this. Your thoughts?
  5. just before you take that new purchase path, a couple of things to just try out.

    a) bios firmware update (also called flashing)
    b) ssd driver udpate

    I flashed my bios but did not see any improvement. I might try doing that again upon seeing that there is a new one available.

    No new updates with the SSD. I already ditched it anyway and I might try a new one if I can solve this spell. It has been like this for sometime now. :( I kinda miss my old setup with no issues.
  7. have you found any answer yet cause I have the same problem with brand new build I have tried all kinds of things even 3 different hard drives with the win 7 64 bit and even using win vista 64 bit nothing has worked for me yet it happens more often when lighter loads to are applied or when idleing I go to bed and wake up to a frozen screen but no temp issues there is just no rhyme or reason for this I started a thread for this but no one has answered me at all this is driving me crazy here are my specs
