Random freezes with windows 7 - 64 bit

Anonymous

I use to run Vista home premium x86 on a acer computer. This summer I downloaded Windows 7 rc x86. A month ago I bought all new parts and since I could use 64-bit system now I installed a 64-bit Windows 7. Then did the problem start. Every new and then the computer freezes, some days over 30 times. I thought it was hardware problem and tried a lot of hardware finders and nothing helped. I also installed windows 7 rc my mothers laptop (The same version I use to have that work fine) that used to run on Vista home basic.. But her computer didn’t freeze it just got a black screen now and then.

The I started to suspect that it was because it was a beta version so when windows 7 were released I bought two of them a 32-bit and a 64-bit. But the problem didn´t go away. It´s still there and It´s kind of frustrating and even more now when I’m trying to write a essay.

I used windows upgrade advisor and it didn´t see any problem with an upgrade to windows 7. What can I do?

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

Here's What Solved It For Me:

I built my computer on June 13, 2011, and the first 2 days of near constant running, I had no problems. Later, I started changing power settings, for monitor sleep, and computer sleep, as well as hibernation etc. Shortly after, my computer would freeze. All windows were visible but no mouse movement, and no keyboard interaction. It was as if my mouse and keyboard were unplugged.

I went into the power settings, and set EVERYTHING for 2 hours, and that didn't work right away. What the problem was (for me) was that there are other settings that need to be changed that most people overlook, such as when the computer hibernates, etc., which are in the advanced settings, and when the harddrive spins down. These settings seem to cause the problem for me.

Here is a link to one of my Google Albums to show the relevant settings that worked for me:

Turn OFF Hybrid Sleep. Turn off... well um, note the settings and please let me know if it helped you!

I had a freeze problem on my Asus A8N-based computer, but with the 32bits version of windows 7. It has been freezing randomly for months, without a starting event or a reason that I could find. I however FOUND A SOLUTION to unfreeze it. Pushing the power button unfreezes the computer, and makes it cleanly shutdown. This is clearly to me the behavior of a IRQ deadlock somewhere on the low priorities IRQs, since the IRQ of the power button surpasses it.

Solution: configure the power button to do nothing in the power management control panel. When your OS freezes, it will unfreeze it and continue as nothing happened. That's not a real fix, but a workaround, unfortunately, since microsoft is not wanting to give us information or help. I hope it works for you all too.

Cheers. Vincenzzo.

My freezing problem started well before the availability of SP1. I think that this is true for most people here. I was hoping that SP1 would fix this. Didn't happen.
