BSOD after .dll error, desktop boots to black screen with a cmd prompt

then the desktop finally loads. It only lasts about 60 seconds before BSOD'ing again. Safe Mode seems ok, but I was in the process of typing up this thread when safe mode shut down on me randomly. I've tried restoring to earlier points and running malware scans. Minidumps are included.

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

* If you are overclocking anything reset to default before running these tests.
In other words STOP!!!

* If you have raid update its Driver.



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.

Any errors are indicative of a memory problem.

If a known good stick fails in a motherboard slot it is probably the slot.

RAM - Test with Memtest86+



Driver verifier

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/Win7 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 "Special Pool", "Force Pending I/O Requests" and "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.

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.

I ran the memtest86 for 19 scans with 0 errors. While doing the driver verifier (the error that comes up on the desktop is /windows/kzdgc.dll or something) it crashed immediately and mentioned HIDCLASS.sys on the blue screen. Now I can't get safe mode to load even as it said Disk Boot Failure but my problem is I bought a student version of 7 last year which was an .iso so I need to download/find a system disk to run system restore off of. Hopefully this gives some insight in the meantime.

I made a system recovery disk from another laptop and tried to restore to a recovery point but the computer is saying it can't see any restore points so I tried startup repair and was able to get back to safe mode and turn off Driver Verifier. Included is the minidump.

Verified and related to HIDCLASS.SYS (Human Interface Device). HID drive things like finger print readers, etc)

Please run a system file check to verify your OS files.

Also of note these old drivers need updating

How To Find Drivers:

- search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
- if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program.

- - The most common drivers are listed on this page: Driver Reference Driver Reference
- - Driver manufacturer links are on this page: Drivers and Downloads

I ran the System File Checker via the command prompt in Windows 7 Safe Mode and "Windows Resource Protection did not find any integrity violations."

OK if it isnt the software causing HID to crash it has to be some hardware. What user devices are installed

I only have a Logitech joystick, Razr Abyssus Mouse, Razr Arciosa Keyboard, Logiteck Attack 3 Joystick, and my WD External Hard Drive. Does the error I get about the windows/kldgc.dll or something have any indication to it?

If those are all unpowered (not plugged in) You have too many. USB (+5.0 volts) is needed to power the devices and when more than ~2-3 unpowered devices are attached they lover the voltage which then can crash the system.

RE: kldgc.dll I can find no information. That may be a sign of infection

Please download the free version of Malwarebytes.
Update it immediately.
Do a full system scan
Let us know the results at the end.

I unplugged down to just my keyboard and mouse. I'll run some antivirus programs and then go back and see if the desktop will load.
