Hello,

I own an HP 6177se laptop for almost 4 years and it is not under warranty anymore (3 years warranty). My issue is that I had some BSOD for the last couple of months that were related to my GPU and I will attach all the files needed in this thread.

my hp laptop uses two graphic card (switchable), intel and radeon 6770m 2gb and so I set my bios to fixed and only use radeon because I play games on it. I used the UnifL driver from leshcatlabs as multiple games asked me to update my GPU driver which was not possible with the drivers from ati and hp website had latest driver dated 2011.

everything worked fine with this laptop until 3 days ago while playing WOT my screen went black and laptop was not responding at all. Did force shutdown and then restart to notice booting gets stuck at windows booting logo (using windows 7 64bit HP) and I sometimes get the animation of windows freezing or a black screen.

First thing I did was a safe mode boot which didn't work as it stuck at loading classpnp.sys everytime. Tried windows recovery and it failed to repair. Used Hiren's boot from usb to use the live windows xp and it showed blue screen as well.

I tried to run ubuntu live cd and it froze as well.

However I was able to run a windows 7 live modified version of wondershare included in hiren's boot and did some diagnostic which would be attached (3DP chip screen shot and PCI32 file)
I did replace some system32 files like classpnp.sys, and the ati drivers which showed in the minidump file with no success.

Finally I opened the laptop to inspect for any visual damage or loose cables and couldn't find anything. Did clean all the dust and applied new thermal compound and put everything together and still same results.

I tried to remove the cd drive, wifi module, switched rams just to know if I have a defective hardware and couldn't boot as well. booted live CD with no HDD same thing.

Fortunately I had another same laptop model from my brother so I switched the HDD from my broken laptop to the other one and it worked fine so the problem is not from my HDD but mostly I suspect my gpu or something in the board which would require me to replace the whole board.

These are links for the photo album for the laptop and link for pci32 and minidump.

I would be grateful for any info to check the hardware as I am not sure what to do now. Board cost around $100 online so that would be my last solution as gpu is integrated for this laptop.

Thank you very much

Update:
forgot to link my laptop specification from hp site

igdkmd64.sys is crashing. And dxgkrnl.sys a file belonging to directx is crashing

This is pretty old NETwNs64.sys your Intel wireless drivers. These can crash. So if you can get into this I would update these drivers

With the video drivers above crashing (and since youre using switchable gfx ). If this is the same as hybrid gfx, KB2670838 was a known cause of the above Intel video driver crashing with a 0x1000007e stop error. The same stop error in the dmp file you posted

If KB2670838 is installed, is KB2834140 installed? If it isnt install it http://support.microsoft.com/kb/2834140

The prob was when KB2670838 was installed on laptops with hybrid gfx, something in this update conflicted with a driver. Thats what made laptops with hybrid gfx crash

Hey Warukyure,

I have two laptops DV6 6177se bought 4 years ago with same win7 64bit and same drivers. As I mentioned one laptop is not booting at all and one is perfectly working. So after all the test I did on the broken laptop I removed the HDD from both laptop and swapped them. The HDD from broken laptop booted perfectly with no issue and was able to get into my files. the other working HDD didn't boot on the broken laptop meaning HDD are perfectly working and no issues with corrupted files, drivers, etc. I didn't format anything.

I have almost all my files backed up and fortunately got the other same laptop. About testing the rams there is an option in Ubuntu to test the memory and did run that to test mine. I also swapped the ram from the two laptops just to make sure and still didn't work.

Hey Paul,

Thanks for the informative reply. Regarding windows update I don't usually do it and only install important ones like DX11, net framework and stop all the security updates. Last time I did update was like 6+ months ago so there should be no drivers of conflicts right? Also, I have two laptops of the same model extactly same OS, drivers, and software installed, and after swapping HDD from broken laptop to working one everything worked and all drivers working while the HDD from working laptop failed to boot to windows on the other broken laptop.

I guess there is nothing wrong with the HDD, OS, or the drivers as I did swap files for igdkmd64.sys And dxgkrnl.sys from the two laptops with no good results.

Is there a boot cd with software that can check the GPU and run test on it? I just want to know that the GPU is actually working as I feel it is partially damaged and windows won't boot once it tried to use the radeon gpu. Also because I have switchable graphics it makes things harder as sometimes I can't detect which gpu i'm currently using.

Thank you very much.

**UPDATE**

I just tried something and made my judgment that gpu is the thing that went bad. Here is what I did:

The laptop uses AMD catalyst control center to choose between high performance GPU (ATI) or low one (Intel). Since In bios setup I chose switchable graphic GPU to fixed and in control center to high performance AMD it will always boot windows using AMD.

I took the HDD from broken laptop and put it in the working one, booted windows 7 normally and switched the GPU to Intel

I shutdown windows and took the HDD back to broken laptop and it did boot, but the resolution was messed up (800x600). I got this box when windows finished booting on the desktop

amd.jpg


I could not fix the resolution because intel drivers was not there for some reason. So went to device manager and there was an arrow pointing down next to AMD gpu driver and question mark on intel gpu driver.

I did click on update driver for intel and it worked then asked me to restart. Once done windows did pass booting and reached to login screen then turned black with flickering dash like it is installing something as you can see on the video.

So you could see that HDD is working fine and all attempts to run live OS failed, removing hardware like CD, ram, wifi module swapping HDD failed to boot the broken laptop but by modifying the catalyst software to run intel gpu (putting the HDD from broken laptop to working one, running catalyst, change and then put back to broken one) windows was able to boot but you noticed the problem of driver.

Does that mean my GPU is damaged and need to replace the laptop board?
Thank you very much

hey paul

I do all the necessary updates for drivers and windows in general but only avoid security ones and I want to keep my system as stable as possible. This should not be the case for my problem. I hope you checked my update for the laptop as it is working now if i force it to run intel gpu, (fixed switchable gpu mode from bios and setting from catalyst center to run intel and not amd).

* I did try to install the update you linked and it couldn't install, maybe it is already installed or can't be done on this system really forgot the message*
I guess I would order the board and wait for it till it arrives then unless someone can give me suggestions :)

thanks alot
