If you've got the spare time and would like to read a rant about dealing with *** hardware, see past the horizontal bar. Otherwise, I have a question.
I was playing a game which became unresponsive and began uttering horrifically distorted audio, grinding, and all sorts of demonic noises and other hellspawn. After promptly exiting the game, the display driver NVIDIA Windows Kernel Mode Driver, Version 347.09 stopped responding and successfully recovered. So I ran diagnostics.
Alien Autopsy returned a failure (Error code: WPE01-E84) which (after the lengthy process described below) has gone away. But could someone tell me what the error code means? Google gives literally only one hit, but that page is in Chinese and google translate wasn't terribly helpful. From what I could gather the only respons suggested running ePSA (I have, it returned no errors, before launching Windows Recovery because windows failed to launch).
So could someone tell me where I might find the reference for this error-code, its severity, and whether or not I might expect to see it again?
To begin with, some system history. I have an Alienware M17xR4 and it is no longer covered by its warranty. While it was still under warranty it began to have motherboard issues. It would forget that the laptop had speakers or a microphone. It also began to have problems with the display. After months of dealing with support, many phone calls and remote accesses, several technician visits, 4 motherboards, and what amounted to basically a replacement of every part of my laptop, the problems were resolved. Or at least, there were temporarily. Unfortunately the problems came back, this time past the warranty expiration date and I was told I was out of luck and would have to pay out of pocket to replace the motherboard. I opted not to buy a new motherboard which may or may not have fixed the issue. So, my computer no longer believes it has a webcam, and (I have switchable graphics) the Intel HD 4000 graphics only renders a black screen. I only use my Nvidia graphics card now.
I put this all up front because I know that my computer's hardware is not in a healthy state. This, despite that even during my support calls, all the diagnostic tests would return a clean bill of health. To this day, the Windows>Sound menu informs me that my webcam is fully operational, when it clearly does nothing. With this machine, I take all diagnostic tests with a grain of salt.
This brings me to today's new problems. I was playing a game (League of Legends) when during a more computer intensive part, my game began to have really bad lag and after a few seconds froze. Meanwhile the audio become horrifically distorted, the voices had that robotic quality as if someone was speaking into a fan and in general was making all sorts of really unpleasant grinding noise. After about ten seconds of this the graphics glitched out, the screen flashed a few times and the game returned to normal. When this happened several more times, I quit the game to run some diagnostics.
While attempting to boot up Alien Autopsy, the desktop became really laggy, then froze. Then the screen flashed and a bubble from the taskbar informed me that the
"Display driver stopped responding and has recovered. Display driver NVIDIA Windows Kernel Mode Driver, Version 347.09 stopped responding and has successfully recovered."
The Alien Autopsy returned the following error, which several Autopsies confirmed:
Xeon(R) processor E3-1200 v2/3rd Gen Core processor PCI Express Root Port - 0151
PCI Express Status Test
Failed (Error code: WPE01-E84)
I then ran the ePSA pre-boot diagnostic tool and it returned no errors. I let it continue on to the extra memory check (which is supposed to take 30min or more) but after two hours I cancelled that test. The reboot after the ePSA took me to the Windows Recovery boot screen to inform me that Windows had failed to launch. So I let it run the Startup Repair process.
This process (which "might take several minutes) ran on for about 30min until I hit the cancel button to attempt restarting Windows without the repair. But apparently I couldn't abort the startup repair. So after another 30 minutes went by the startup repair finished its job and I successfully booted up to the desktop. Rerunning the Alien Autopsy informs me that all the tests were passed.
