Windows 7: W7 Random lockups

windows 7 professional x64

Hah I knew it :P

Indeed, to run the memory on 1600mhz you have to manually overclock it, OR use the OC Genie feature. This also puts the voltage up which results in no more crashes

Windows 7 64bit

Hi all,

I've been getting the same thing on my new build.

I have the following build:

i5 2600k (OC @ 4.4ghz)
8GB corsair vengeance 1600mhz (was 1.5v now 1.6v)
sapphire HD6970 2gb
WD raptor 150 x2 on RAID 0
MSI P67GD65 (B3) motherboard
Corsair TX750 PSU
Win 7 HP 64bit

I've been experiencing similar full systems freezes, that do not recover. Been trying everything I can, memtest passed, defragged, updated all drivers, the lot... the last thing i tried was changing the ram voltage. I've not had a freeze yet but it's only been 20 minutes or so.

Anything similar happening to you guys?

I have the same issue with 64bit Win7 Ultimate. My specs: i5 2500k, gtx570, p8p67 pro, corsair 2x2gb 1600mhz cl9. Freezes are totally random, last time i had them was today, but before that last time it happened was one week ago... It happens no matter what i do - it can happen when im playing games, browsing the net or just when PC is left alone... And other weird thing is that HDD disappears when freezing happens. It only reappears after I power off and on again. Tried memtest86+, samsung hdd test utility, which ran for 2hours and everything showed up fine, no errors... It must be windows issues, or unstable power providing in my building, because sometimes my lights go brighter or less brighter, my older laptop's screen was self dimming or brightening randomly, but not when on battery... But im not sure if it's exactly that... I think more likely windows is causing all thistr. God i hate this

Windows 7 64bit


I've sorted the issue now. Took ages, seriously.. but it's sorted.

I made a list of all the steps I did during the Windows 7 installation; drivers, updates, applications, games etc...

Then reinstalled windows 7 and all of the above one by one. When i hit the issue, I ticked off the installed bits I'd made. Eventually, 4 installs later I found it to be a dodgy driver for a Logitech G19 gaming keyboard. With that driver not installed and the rest from the original list installed and tested I've now had over a week of perfect performance.

My suggestion is go through your event logs with a fine toothed comb, that's what I did to find this driver issue (that and the multiple installs of windows to test the theory).

It took me 13 hours to do the above. It might take you less if you choose this method of investigation.

Good Luck!
