Random freezes with windows 7 - 64 bit

My problem was only with facebook on windows 7.  I fixed it if you will by just using facebook on my chrome browser where I use it exclusively and it has never frozen since.  On the other hand a neighbor has a toshiba laptop identical to mine and hers freezes when she is on yahoo.

Hi

I did not know how to make my own treaht here, so I just replyed. I have this random frezzes also. Getting very annoing. But I notices its happen diffrently when playing diffrenten games. For eg. when I play The Secret World, it rarely happen, the frezzing part. But when I play GW2 it happens randomly from 5-10 mins or more. I fix it by pressing ctrl+alt+delete and press start joblist and then my computer unfrezzes and i can use it again. Well its not my entire computer that frezzes, its my mouse that stop working. I can move around with mouse, but I cant click on anything, unless I do that ctrl+alt thing. I to, have a

Intel core i7

mother: asus

12bg ram

and videocard is gforce 560ti.

This 1.6V thing did solved my problem when I had two modules of DDR3 ram.

When i upgraded and used all the slots on my intel motherboard (4 slots) I had to again use the default 1.5V, and it is now working flawlessly.

Guys,

I might have the answer to your problems.  This might fix your sleep/suspend problems and your random freezing problems.  Bottom line is that the default and "auto" values in Win 7 and your BIOS might not produce a stable computer...even with a virgin install.

RANDOM FREEZES FIX:

My computer used to freeze randomly until I fixed the memory timings.  I suspected bad memory early on and tested it with MEMTEST, but it passed with flying colors.  I even tried swaping memory out, trying to eliminate bad memory and/or slots.  It turned out that it was a memory frequency/timings/voltage issue.  No more freezes!  If you have a similar setup, this will most likely fix it.  If not, then check your memory and/or power supply.

The "AUTO" settings in BIOS *may not* produce a stable setting.  You have to goto the ASUS support website and download the latest memory QVL and lookup the memory settings for your particular brand there.  For my memory (OCZX1333LV6GK(XMP)) I had to make the following adjustments in the BIOS:

DRAM Freq:1066  (even though my memory is rated at 1333 frequency, the QVL guide recommended a lower freq!)

7-7-7-16 for the rest of the timings.  The other settings I was able to leave in "AUTO"

DRAM BUS Voltage: 1.6

*warning: be sure to consult your memory/motherboard documentation...the wrong value could damage your components!

SUSPEND/SLEEP FIX:

My computer used to hang when coming out of sleep or wouldn't completely goto sleep.  This solution may be partially dependent on you fixing a random freezing issue if you have one. 

In your "advanced" power settings, disable "Hybrid Sleep".  That's it!  My motherboard doesn't like hybrid sleep.

*If you have a desktop with a UPS, Win 7 will treat it like a laptop and apply the battery settings....sooo make sure you adjust the "on battery" settings!

My setup:

Processor:Intel core i7 920

Motherboard:Asus P6T

Memory: OCZX1333LV6GK(XMP)    (ie. 6GB in 3 sticks)

Harddrive:  3 x WD Caviar Black drives in RAID 5

PSU: X3 1000W

Video card: 2 x NVIDIA 9800 GTX+ SLI

*I have all of the ASUS overclocking/energy savings programs uninstalled

*I have the latest BIOS 0801 and all the latest drivers installed

most cases is graphics card, try to use on-board vga or get a graphics card you will see that graphics card is failing.
