Blue screens, Windows 7, Need your help

Nuts, sorry the problem is not resolved. dxgmms1.sys is a directX driver and it may or may not be the cause. Now it is time to start looking at hardware. Here is link you might want to visit for more information regarding dxgmms1.sys.

dxgmms1.sys crash – Blue Screen Of Death

Please fill out your system information. Go to your User CP at the top of the page, look in the left column and click on Edit system specs. Filling in your specs will help us help you.

You can make this easier by downloading Speccy.

This could be triggered by your video card. What card are you using?

If you are overclocking please return to stock settings.

Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder. Boot from the CD, and leave it running for at least 7 passes. Post back with your results.

If Memtest checks back clean after 7+ passes, follow these instructions for enabling driver verifier: Using Driver Verifier to identify issues with Drivers
Please follow these instructions in order to run it:

Using Driver Verifier is an iffy proposition. Most times it'll crash and it'll tell you what the driver is. But sometimes it'll crash and won't tell you the driver. Other times it'll crash before you can log in to Windows. If you can't get to Safe Mode, then you'll have to resort to offline editing of the registry to disable Driver Verifier.

So, 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/Windows 7 Startup Repair feature).

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).

Reboot into Windows (after the crash) and turn off Driver Verifier by going back in and selecting "Delete existing settings" on the first page, then locate and zip up the memory dump file and upload it with your next post.

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.
If that doesn't work, post back and we'll have to see about fixing the registry entry off-line.

Please keep us updated on your progress.

Softgator, that would seem to indicate that you have a bad RAM stick. Now you need to isolate it. Open the case and remove all but one stick, then run the test again. Repeat this for all the RAM sticks.

During the test with first stick, did you test it on different slot? If you continue to test, I think still at least 6, 7 passes.
It never hurt to try. Manufacture's site always give out the last update for Bios that can fix some problems (BSODs). Go ahead and do it

For your first question: Yes, why not
Do one stick on different slot first. If no error-->slot ok. Then you don't have to test it on diffferent slot. Got what I meant???

Softgator, take a known good stick and test it in each slot. Five passes should do for these tests. After you determine that all of your slots are good, you can test the remaining sticks, singly, in any slot. Yes, it is involved and tedious; but it is the only way.

Looking at that screenshot, I can tell you that you have a bad RAM stick, maybe more than one.

The ways to test it can take a while yes, but the good news is that the bad sticks should show an error very quickly, so you don't need to run it for all 7 hours.
