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

Same here. I'll be using the PC normally and it'll just completely freeze with a hard reboot being the only way to shut it down. Can't indentify an application that causing the issue as it's done it on a few occasions when I've just been navigating through folders. It's intermittent and I can't find anything in the event logs that correlates with the time that the freezes occur. System was entirely stable under XP and I installed Win 7 Home 64 on a new a brand new hard drive from scratch.

System Specs :

Intel Pentium 5200 dual core

4gb corsair ddr

Gigabyte GA-EP43-DSL

WD caviar black 1TB drive

edimax ew-7128g wireless card (using vista 64 drivers from mfr website)

Now, I did think that this could be the wireless card, but the RC of Win7 was doing the same thing prior to the installation of the card. To be on the safe side I've removed the card and drivers and strung an ethernet cable through my house, but I'm still getting the same problem.

Im in the same boat.

Asus p7p55d deluxe moboi7 860Ati 58704gb Dominator ramWD 1tb drive

Win 7 premium 64 bit

Creative x-fi xtreme music

Built my machine last week, installed win 7 and it ran as sweet as a nut all of a sudden at the weekend i loaded up left 4 dead 2 demo and ten mins in2 playing it froze and the sound kept looping over and over. i ctrl alt del'd it and wouldnt respond right away. i waited 5 mins, the screen went black then task manager popped up. I closed everything down that wasnt responding. This was the first time i noticed it. After that it freezes up constantly although it always comes back to life after 5-10 mins but its a pain in the backend. I have tried each individual stick of ram, (that was my first thought) no joy. I thought it could be a virus every scan is clean. I cant help thinking it may be some auto update wit bad driveres that has caused this or the fact i ran ccleaner- everything is a suspect. Ive uninstalled drivers. reinstalled drivers. still no joy. i have added another HDD and installed vista 32 bit and my machine is perfect. It is definately software related to win 7. I hope this gets fixed soon as i was really liking windows 7 and im gutted i'm back to vista. Does evey one that has this problem have a creative sound card installed? (Again grasping at straws)

Nope, I'm using my mobos onboard sound drivers. Not sure you've got the same issue as the rest of us as you can (albeit partially) recover your system, whereas the rest of us require hard reboots. It's a strange problem though and obviously pretty serious if it's making the system completely unresponsive.
