Windows 7 windows crashing issues

[Russ Michaels]

running windows 7 ultimate 64 bitthe system keeps crashing/freezing, no BSOD, nothing in the event log, just complete system freeze.
sometimes it may crash several times a day, sometimes it may go for several days without crashing.
Some things I have found which regularly cause a crash.
Trying to print.
starting a program
web pages with flash or video

I leave my computer on 24/8, and it even crashes at night when it is not in use.

What I have tested....I ran memtest overnight, and problems with RAMI have replaced hard drivesI have tried 2 different graphics cards

Have tested the PSU with a PSU tester, no issues.Unplugged all external devices other than keyboard, monitor and mousestill problem persisted.So I have done a completely clean install of windows 7 on a new disk.Still the same problem.I don't have any way to test the CPU or motherboard as possible causes.I have run windows in safe mode for several days, no crash.
I have run from Ubuntu live for several days with no crash.
So it does seem to be a windows issue.

I cannot get a crash dump as the system is completely unresponsive, I have already followed instructions for force a crash dump via keyboard when it crashed, but this doe snot work.
The few times the system has BSOD'd, it does not create a dump file or the file is 0kb, there is plenty of space on the disk, and it is setup correctly as per the M$ KB article.

any suggestions.

It seems like you've done a thorough job troubleshooting your system already. Since you've tested the RAM, changed hard drives, tried different graphics cards, checked the PSU, and even reinstalled Windows on a new disk without resolving the freezing issue, it's time to consider some other possibilities. Given that the system doesn't crash in Safe Mode or while running Ubuntu live, the issue may indeed be related to Windows itself. Here are some further steps you can take to investigate and potentially resolve the problem: 1. Update Drivers: - Ensure all your drivers are up to date, especially graphics, chipset, and network drivers. 2. Windows Updates: - Make sure your Windows 7 installation is fully updated with the latest patches and updates from Microsoft. 3. System File Checker (SFC): - Run the System File Checker tool to scan for and repair corrupted system files. 4. Check for Malware: - Perform a thorough scan for malware using reliable antivirus software to rule out any malicious software causing the freezes. 5. Event Viewer: - Check the Event Viewer for any critical errors or warnings around the times of the freezes to see if there are any clues there. 6. Power Settings: - Adjust power settings to ensure that the system is not going to sleep or experiencing power management issues. 7. Temperature Monitoring: - Monitor the temperature of your CPU and GPU to ensure overheating is not the cause of the freezes. 8. Check for Background Processes: - Disable unnecessary startup programs and background processes that could be causing conflicts. 9. Backup and Reset BIOS: - Backup your BIOS settings, then reset them to default to rule out any BIOS-related issues. Since the issue seems specific to Windows running normally, the problem could lie in a software conflict or corruption within the Windows installation. By following these steps, you may be able to pinpoint the root cause of the freezing problem. If none of these suggestions help, considering that the issue does not occur in Safe Mode or while running Ubuntu, it might be worth exploring more advanced troubleshooting steps or seeking professional help for diagnosing potential hardware issues with the CPU or motherboard.
