BSOD Win7 64 6-8 times a day KMODE_EXCEPTION_NOT_HANDLED

Dell T5400
4GB RAM or 11GB RAM
Win 7 64 Professional upgraded from Vista 32 OEM
Nvidia Quadro 4000 upgraded from FX570
1 120GB Intel SSD for OS and programs
1 1TB Hitachi for Data

Crashes BSOD numerous times a day. Ran memtest86 4.0 on both RAM configuration. BlueScreenView gives much data but hard to point finger at any one thing. For video card went into safemode w/net and removed all Nvidia drivers/programs and folders and then back into normal boot for clean install of driver for Q4K and still get BSOD. Frustrated please help.

These were caused by a memory exception. Please run these two tests to verify your memory and find which driver is causing the problem.


1-Memtest.

*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Memtest86+ - Advanced Memory Diagnostic Tool

*Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

RAM - Test with Memtest86+



2-Driver verifier

I'd suggest that you first backup your data and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Win7 Startup Repair feature).

In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

Driver Verifier - Enable and Disable

Tested memory for a longer period and it went fine. How do I maike a restore CD if I dont have a CD/DVD burner?

No crashes but everything responds slower how long do I wait for BSOD before giving up on this setting and how do I turn it off so that it runs with a normal response?

Not really sure whats worse, constant BSOD or trying to stress the drivers and have a system that does not work. Web pages often eternally wait to load. Rhapsody fails to stream music. This has caused the machine to just dial down to a crawl and most apps that I really need to use just run to slow to even use. The resouce monitor shows that the CPU load is not even breaking a sweat and there is still free memory. If I walk away from the system (because I can't work on it) is hybernates and obviously there is no stress in hybernating. Is there anything I can do to accelerate this. At least with the BSODs I could get work done in between them.

RESOURCE MONITOR shows TCP connectoins spiking and jamming up. If that info helps...

Anything that connects to the network is grinding to a near hault like an ATT server with an iPhone

This is ridiculous! I don't want to throw a virtual tantrum here but these tests pretty much make my system a $5K+ 11GB 8core Xeon SSD 1TB pile of fecal matter in the corner. I cannot use my system as usual as it cannot open web pages and clearly something has gone afoul with Trend Micro AV as it does not open the main console properly any longer. This is why I bought my wife a Mac and never have to troubleshoot it. Please if anyone would like to buy this overpriced POS PC please contact me. I need to spend my time getting work done using my tools rather than trying to constantly figure out why they are not working. My toaster makes toast everyday and doesn't need to be fixed because of some update for the coffee maker.

If verifier is running and you need to do work instead of fixing the problem disable it. I understand you are frustrated but it has only been one day since the thread was started.

48 hours and no BSOD. All it has done is screw up my interent connection. Anything that needs to connect to the net is slowed down or just doesn't connect while verifier has been running. Does an aging powersupply manifest in these ways? the machine is not that old, but Dell has a poor track record with capacitors and power components.
