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

I'm also experiencing random freezes. It's really frustrating because I'm running RAID1 and it takes an hour or more to complete verifying. Arrh!

I've got hardware RAID 1 as well.

Has anyone checked or applied the hotfixes I stated above?

Also if you run ZoneAlarm there are problems.

Hi Everyone,

I am a member of the freeze club too. I was running fine for over a week and then it happened. I will list my specs and then discuss what I plan on trying.

ASUS P6T DELUXE V2 - Latest BIOS and drivers from ASUS

i7 920 CPU

CORSAIR 256GB Solid State Drive

Corsair 850 Watt Power Supply

Corsair Dominator RAM 1600 12GB 6 X 2

Plextor DVD Writer

ATI 5780 Video Card

Using onboard sound and network

Stock settings, no overclocking

Idle temps are 30 C

I own and operate a computer shop which makes this ironic. www.computerlift.com

It has happened 4 times in 3 days. Hard screen freeze, nothing responds but push and hold the power button.

I have noticed that it only happens when I am using the machine. I left it on all night with no problems. I ram Memtest Four 6 hours, everything passed. I was using Office and Accounting all morning yesterday and it worked perfect. I went on Ebay and it froze. Rebooted, went to Ebay using Firefox and it froze when mousing over a drop down.

It seems like moving the mouse over a drop down menu or scrolling the mouse has caused it almost every time. I was using the MX1100 and have switched to a wired mouse. It can't hurt. This problem really has me stumped. There is no event warning in the log. There is no dump file. There has never been a BSOD.

I am going to try the Windows Media Network Service fix posted above. I am going to see if Intel has a newer chipset driver than ASUS. I am going to switch to a cabled keyboard. My plan is to work through all my peripherals before looking at the innards. I guess I might look in the BIOS for a voltage to tweak.

I will report back how all of these work. I hope we can get this problem solved.

Hey, I also have my brand new laptop with Windows 7 64 Bit.

What I noticed is that it only froze when a particular USB device was used. Again it'll run for a few seconds or even up to an hour (only happened once) until it froze and the same, the only way out is to hard-boot. When that particular device isn't connected i do not receive any freezes, at all.

Just as a thought, though maybe hard for some of you, is disconnect all the USB devices you have and see if you still have issues. As I say maybe hard as I bet you have a keyboard and Mouse all connected by USB. And of course there are those USB devices connect internally.

This is the solution that has worked for me, so maybe not the same as the rest of you(?)
