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

Ok Posting back.... its been 2 days, and I just had another screen freeze

As mentioned in my earlier post, I had upped my system performance to high, and turned off aero. That didnt help - in fact, it made things worse. This time, I got a BSOD, where before, I never got a BSOD.

When my puter recovered, there was this error:

Problem signature:

Problem Event Name: BlueScreen

OS Version: 6.1.7600.2.0.0.256.48

Locale ID: 1033

Additional information about the problem:

BCCode: 116

BCP1: FFFFFA80081914E0

BCP2: FFFFF88004D61028

BCP3: FFFFFFFFC000009A

BCP4: 0000000000000004

OS Version: 6_1_7600

Service Pack: 0_0

Product: 256_1

So I turned my performance back to balance and turned aero back on.

Ugh, so wish theyd put out an update to fix this......

Right, after the usual response (none existant) from Acer support I've pulled the cover off the back to get at the memory. Two different makes of memory installed and I now suspect the upgrade to 64 bit has exposed a memory problem, because Win 7 64 bit is addressing it all. Previous OS was 32bit Vista, then XP and probably cobbled themselves round the duff memory. I've pulled one of modules, leaving the one that is clearly marked ddr3 8500 in situ and everything is running fine. Off to ebuyer now to get a 4gb ddr3 crucial kit and try that.

Running on the single 2gb and no lock ups/freezes. I'll drop back an update after I've installed the new matched memory.

I think Win 7 64bit is a bit more particular about what is on board memory wise.

I don't believe it! It froze on both memory sticks run seperately. Still no response from those muppits at Acer though.

Right I have 4gb kit of crucial on order. The samsung stuff in there at the moment goes on ebay, no real problems with it. I've re-installed Windows 7 64bit but this time I've only re-installed Norton AV and the free ZoneAlarm applications. No driver updates and no MS updates.

This set up has been running for 6 hrs with no freezes, lock ups etc. I intend to install the correct drivers from acer, still no bios update yet though as I've found the invoice date for the m/c and it's still in warranty, and they do warn not to use them unless directed by their operatives. HELLO whats the point of putting them up there for download!

Tomorrow I'm going to install the correct drivers from Acer and run it over the weekend, after that the MS updates, 51 stacked at the moment..interesting but I'm now beginning to believe more on this forum about Microsoft have screwed up somewhere. Updates later but running at the moment no problems,

Regards

All
