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 have a Gateway NV7901u

Intel i5 430 @2.27 GHz Turbo Boost to 2.53GHz

ATI Radeon HD 5650 with 1GB of dedicated memory

8GB RAM

2 500GB HDD's System HDD is 7200rpm Secondary is 5400(if it matters)

Running Windows 7 64-bit

Prior to this laptop, I have a Gateway NV55C03u

Intel Pentium p6100 @2.0 GHz

Intel HD Graphics with GMA Accelerator

8GB RAM (Now 4GB)

500GB @7200rpm (Now 5400rpm)

Running Windows 7 64-bit

I still get this error, not to mention the freezing when I am watching a video(very common) or playing music(extremely rare) I think it has something to do with my RAM, but I can't replicate the instance when it happens because it's so random. I still have the Gateway NV55C, and I have played on it since I switched out my components to my higher-end laptop.

I haven't had any freezing issues with it, though. When I upgraded to NV7901u, I just took out my old HD and placed it into my newer laptop, and let windows download the missing drivers it needed(there was no need to reinstall). I took out the 4GB RAM that was in the NV7901u as well and replaced with the 8GB RAM that I purchased for my NV55C03u(Both run on the DDR3 PC8500 1066mhz 240-pin). Still getting the random freezing in flash and other media playing, and the Video Driver Recovery error.

Any ideas?

I have an iMac running Windows 7 in bootcamp.

I have random lockdowns and freezes too. I was getting black screens, but I downloaded the new nVidia driver today, and that has stopped the screen from turning black, now I can actually watch everything on my screen stay frozen until I restart. I don't have a piecemeal machine, I can't run out and get updates from ASUS or other venders.

I honestly don't even know what to do at this point.

A software developer i know told me that Microsoft have changed the way DLL's interact with EXE files recently and this is causing all sorts of problems with software.

For the record i have an Asus motherboard and Win7 x64 and am getting freezing. also problems playing video in IE9 freezing up on screen... and hogging memory.

I find switching to google chrome fixed the video problem, but the computer freezing up is still causing me grief. Next thing to do is switch to another OS...

I will wait until then next Microsoft update early next month and it that doesn't fix it then Win7 is toast !
