Random freezes with windows 7 - 64 bit

I've been doing a fair bit of research into this matter and it appears that AVG 9 seems to be a significant trend to this problem .

Out of interest, how many of you guys that are experiencing this problem are running AVG?

I was. I have removed it and replaced with Microsoft Security Essentials . Since this I have had no problems. (Fingers crossed).

Good luck!

I'm using AVG 9 as well. I was using Microsoft Security Essentials a few weeks back until the system crashed and I had to do a clean install. I'll stick with AVG until someone finds a resolution. I don't want to go through the hassle of a reinstall just now.

Hi,

My random freezes was triggered by a 100% HDD activity time without any or low I/O value. My first thought was a defect HDD so i checked these case without any result. The EventLog shows me many advices with the EventID 7036 (divers messages, "Dienst "Diagnosesystemhost" befindet sich jetzt im Status "Beendet"". is a message frequently seen).

in my case the only working "solution" (It is not exactly brilliant) is to disable the "Diagnosesystemhost" and "Diagnosediensthost" (sorry i dont now the service-name on english systems).  I tried many other things like various driver for various components, disabling several tasks (Prefetch, SearchIndexer, and so on), clean system install (incl. required applications),  changing RAM / CPU / BIOSsettings, changing system settings (Temp-location, swap-file size, ..), sequential installing win updates but nothing helps except disabling services named above.

Up to now i cant discover the real catalyst :/ Indepentend from these freezes i ordered a SSD now, but possibly it solves the problem because from time to time i read about problems with WD Green HDDs on Win7 (?).

I think it is a Win7 / Win7 Driver problem, because before i installed Win7, my system runs very fine on Vista Ultimate (proper system specs (software and hardware))

System: WIN764Bit Ultimate, I7 920 (OC / without OC), Corsair HX3X12G1600C9 XMS3 (12GB), Asus P6T WS Pro (Bios 0804), Western Digital WD10EADS, Asus GTX 275

Edit: I laughed to soon, after few hours without problems, win7 freezing again (but in a lower frequenzy). It's very annoying, it's not possible to work with this machine and the point to drop the complete pc out of the window come closer and closer.

BTW: Sorry for my bad english, it's a "little" bit rusty :)

Okay, that driver definitely did not help.

In fact, Windows froze on the "Windows 7" animation during boot up BEFORE it even reached the desktop.

I'm starting to lean towards the possibility it's not a Windows issue and is, instead, motherboard related...for me, anyway.

In my case, the following critical errors always occur before the freeze:

Event 219, Kernel-PnP

The driver \Driver\UBHelper failed to load for the device IDE\CdRomHL-DT-ST_DVDRAM_GT30N_____________________1.01____\4&1f2e3f97&0&0.1.0

or

Event 1001, Dhcp-Client

Network Card with network address xxxxxxxxxx. The following error occurred:0x79.

Your computer will continue to try and obtain address on it own from the network address

I sometimes have no freeze for a day and then the next day freezing several times in one hour.

I also tried to disable the 'Workstation' service but noticed that it actually caused the freeze in some cases.

I am stumped as to what may be the issue here with your PC. I have tried to wrack my mind what could be the cause. Let me take a stab at it and see if you I can help you. It does seem that either a task process or a Service that is running is triggering this freeze and upon disabling this service or setting it to "manual" mode it may prevent it from happening. What this process is I can not tell you since I do not know the litany of services or processes your PC may be running and they may be different from mine. Based on the limited information I have above it would be a stab in the dark to the conclusion of the exact process/service.

I will recommend you go into your power options and change the setting from "Balanced" to "High Performance" until this aspect of Windows 7 is resolved. There is a problem with spontaneous restarts and now Win7 handles partail system power downs when the computer is not in use or you are away form the computer for a time. You can also create a custom power scheme and disable specific components to not power down. For instance I do know that if the plan has the monitor set to power down it will NOT crash the system. The monitor power down does work. That much I am confident of. I have my suspicions on the hard drive power downs and the network card (NIC) power downs if you have "green" versions of either of those components.

If you create a custom power plan. Enable one other component besides the monitor to power down and run it that way for a few days. If you system is stable, keep adding additional components to power down. With the power options control panel running in "high performance" you will manually have to shutdown the computer when you are done to conserve energy until a service pack or hotfix is released for this issue.
