Hello, I am running a windows 7 pro 64bit system which started to freeze and die without any further notice. It is often just idling around when that happens. I have energy saving options to go into stand by after 30 mins so I disabled that. No effect. I am not sure if software is responsible for that or some of the automatic updates windows does all the time The event log (sorry, my windows is localized so I need to translate everything) just shows the following events: http://pastebin.com/wu78ZiaA Bottom up. Bottom is first event after booting. Is there a way to get the description in english for you to debug? Some translation: Fehler = Error, Warnung = Warning, Kritisch = Critical Can I enable some diagnostic output for that? I dont even get a minidump to debug it in visual studio and my windows debugging skills are still in development :) Is there some persistant monitor tool that outputs everything I do into a file to reproduce that issue? Thanks Sam

Could be hardware issue, could be power management or it could be a software/driver issue. Scan your disk for possible problems, nice description located here http://www.w7forums.com/use-chkdsk-check-disk-t448.html Insure drivers are updated, insure windows is updated. Check manufacturers website for updates, check bios revisions for possible related fixes. These are general and basic tips. My windows debuging skills are also in development but I am sure others will ask you for more information or to upload logs so they can check for possible solutions Good luck with your endeavor Carl

Hellow again, all these issues have not solved the problem. I have run chkdsk, it fixed some parts but later it kept freezes. Updated drivers, no effect. No I a running Prime95 for several hours as stress test for cpu and ram. It still works stable. Windows usually keep freezing while doing nothing, so I rather think that it is not the hardware (cpu / ram). Sam

I understand from your response that chdsk froze part way through. If so, combined with the fact that prime95 found no problems with the CPU/RAM that the problem is most likely drive or drive controler related. If you have already updated the manufacturers chipset drivers for the motherboard I would suspect the HDD. Identify your drive, download the drive manufacturers diagnostic utilities or use a third party drive diagnostic utility. Sourceforge is a good source for trust worthy utilities.

Hello, chkdsk fixed some journal entries and so on but it never freezed during execution. So altough chkdsk could find some error it did not solve the basic issue. I ran harddisk diagnostic tools for all my hard drivers. No bad sectors found. Anywaylong time ago I hada disk with bad sectors. The way it caused issues was typically not freezing but first many clicking sounds followed by IO error. If some important sectors would die then I would notice that much earlier. Now I am running out of possibilities

computer runs fine while under load, using prime95 and you have checked the hard drive. Seems to happen when the computer is idle. Most likely the hardware and power supply are fine, running prime 95 for a coupld of hours should have found most problems and/or brought a flaky power supply to it's knees. Sounds like power management to me, check the manufacturers website for updates, check for updated bios that may address related issues. Try adjusting power management features. Do not have the drives shut off, if you have an LCD monitor increase the time required to go to screen saver or shut off the monitor. I suspect power management or a hardware conflict.

Disabled any power managment it has. No monitor shutdown and so on. And today it was only 20 mins running and it got frozen. Damn thing. There is nothing to upgrade anymore and no conflicts displayed in the hardware list

I do not know if you have this luxury or not but can you take out the hard drive and try plugging it into another computer? run a chkdsk through that computer and see if the hdd freezes if you leave it idle for a while. I mean it could be a multitude of things.. but normally its either a bad hard drive, RAM or power supply. Did you run the Windows 7 RAM check program? Try using a SMART hard drive program to see if there are any issues with the hard drive.

Hello, I am not sure when the rumor appeared that chkdisk caused a freeze because it didnt. There is no other pc here to test my disk. SMART is always enabled. The hdd test tool from the manufacturer verified SMART information and integrity of the disks. The ram check produced no results

Could be a bad component or device, disable sound, unplug optical drives, disconnect USB devices and see if it still freezes, if not then reconnect and or enable devices one at a time (allowing sufficient time to reproduce the problem) until the behavior returns. If you isolate the component try downloading drivers, check the manufacturers website for known conflicts and compare against your system, check the motherboards site for the same information. Could also be a bad drive cable, check those, could even be a power supply however I think that prime95 should have stressed that enough to cause issues, however, maybe not. Check to see if you have any third party software that may be at fault. Try a system restore to a point prior to the first occurrence of the problem.
