memory corruption caused by an un-named driver

I would run memtest

Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. 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.

And Driver verifier to find which driver

Quote:
I'd suggest that you first backup your stuff 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.

very well, i will try that. i have already tried Memtest on all my RAM some time ago, and at 9 passes it said no errors. i'll try every stick individually now.

dont forget Memtest tests both the Ram and the mobo slots. So by testing a known good ram stick in the different slots you may uncover a mobo slot problem that has been hiding for a while



Good Luck and thanks
