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

Any of you guys try to use the repair function on the OS disc during boot up? It worked for me, now 48hrs freeze free. I also did a C drive scan repair and a few errors were repaired.

Had another crash - this time with Skype - caller stated "hello hello I can't hear you" - 10 seconds later apps became unresponsive - 10 seconds later mouse froze - waited 5 minutes - still deadlock. So my problem is not resolved - still convinced it's sound driver or network card.

Nothing in the event log either.

I have loads of errors in the event log and have searched for them and no luck with anny the main one was Error 100

Does anyone get these errors?

Just done a clean install at the hope of installing drivers one by one will eliminate the problem...I KNOW ITS A LONG SHOT

I was running vista x86 business for quite a while and everything was dandy but had the occasional BSOD because of memory management. Decided to do a clean install of Win 7 x64 Professional and this is where the problem starts...

Firstly Specs:

MOBO: Asus P5Q-Pro

CPU:    Intel E8400 3.0 Ghz

RAM:   OCZ 4GB (2x2GB) PC2-9200C5 1150MHz

GPU:    Powercolor ATI Radeon HD 4870 1024MB GDDR5

HDD1: Samsung HD753LJ 750GB Hard Drive SATAII 7200rpm, 32MB Cache (Win7 installed on this)

HDD2: Seagate OEM 500GB Barracuda 7200RPM, SATA, 16MB Cache

Onboard Sound and have a D-Link G MIMO PCI card for wireless

Freezing completely randomly and could be in the 1st 5 mins of startup or 3 hours!!! The only possible reason i can think of is driver related! Have done stress tests on every component and even thought that running a hard drive test with SeaTools in DOS would find something because no windows files would be used in that process. STILL NO LUCK!

Anyone with any remote similarity to me plz contact or post your thoughts.

Hope we get this sorted soon.
