BSOD Stop : 0x0000007E

Hello I am having problems with my y570p with

i7 2630QM 2.00GHZ

nvidia gt 555m



regarding a BSOD error. The code is:



Stop : 0x0000007E (0xFFFFFFFFC0000005, 0xFFFFF8800F7E4987, 0xFFFFF88003576B48, 0xFFFFF880035763AO)

nvlddmkm.sys

Address: FFFFF880F7E4987

Base: FFFFF8800F235000



I know its a problem with the GPU because several times it auto-rebooted when the screen happened the system would not register the nvidia 555m gpu using Riva tuner and would recognize again after I did another reboot.



I've tried to install new BIOs but recieved the "the version of rom file isnt newer than that of bios" message. I've installed new powermanagement drivers.

This laptop is relatively new... I've only had it for around 3 weeks.

So far the only time the BSOD dumps occur is when I'm NOT in a game but rather when I'm surfing the web (using Opera).



Any help would be greatly appreciated.

We do need the DMP file as it contains the only record of the sequence of events leading up to the crash, what drivers were loaded, and what was responsible.

You may be able to get the DMP files without crashing by booting into safe mode (F8) with networking.

To enable us to assist you with your computer's BSOD symptoms, upload the contents of your "\Windows\Minidump" folder.

The procedure:

* Copy the contents of \Windows\Minidump to another (temporary) location somewhere on your machine.
* Zip up the copy.
* Attach the ZIP archive to your post using the "paperclip" (file attachments) button.
*If the files are too large please upload them to a file sharing service like "Rapidshare" and put a link to them in your reply.


To ensure minidumps are enabled:

* Go to Start, in the Search Box type: sysdm.cpl, press Enter.
* Under the Advanced tab, click on the Startup and Recovery Settings... button.
* Ensure that Automatically restart is unchecked.
* Under the Write Debugging Information header select Small memory dump (256 kB) in the dropdown box (the 256kb varies).
* Ensure that the Small Dump Directory is listed as %systemroot%\Minidump.
* OK your way out.
* Reboot if changes have been made.

Here you go, sorry about that. I was reading threads with similar issues with this particular 0x7E error and I reinstall the newest nvidia drivers after uninstalling and using driversweep

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

Found the problem. It was due to a faulty driver by nVidia for 280.26

Glad to see you are working
